Ancient eastward migration traced in genes

The Development of the East Eurasian Phenotype

The East Eurasian phenotype — the set of physical traits common among many East Asian, Siberian, and some Southeast Asian populations — didn’t appear overnight. It developed over tens of thousands of years as ancient human populations adapted to diverse climates, diets, and environments across the vast lands east of the Eurasian Steppe.

Modern genetic studies suggest that many distinctive traits — including epicanthic folds, shovel-shaped incisors, thicker hair shafts, and skin tone variations — evolved as adaptive responses to cold climates, UV radiation, and dietary factors during the Upper Paleolithic (roughly 40,000–10,000 years ago).

These traits are believed to have crystallized among ancient hunter-gatherer populations in northern and eastern Asia, particularly in regions like Siberia, the Yellow River basin, and the Amur River valley. Later migrations spread this phenotype widely — into China, Korea, Japan, and Southeast Asia — blending with local groups over millennia.

Genetics also shows fascinating connections between East Eurasians and Native Americans, who migrated across Beringia during the Ice Age, carrying parts of this shared ancestry into the New World.

This story is still unfolding, thanks to ancient DNA research — revealing how migration, climate, and time have shaped the diversity of human appearance across continents.

Since the early 20th century archaeologists could show that Australia was criss-crossed by Aboriginal trade routes. For Isabel McBryde – ‘the mother of Australian archaeology’ – these Aboriginal trade networks were ‘among the world’s most extensive systems of human communication recorded in 'hunter-gatherer'* societies’.

Goods and people travelled vast distances: the Dieri people, east of Lake Eyre, South Australia, visited places at least 800 kilometres apart; while shell from Papua New Guinea reached western New South Wales (Gammage, 149).

Every individual was touched by trade: as archaeologist John Mulvaney has written,
‘it was possible for a man who had bought pituri from the Mulligan River and ochre from Parachilna to own a Cloncurry axe, a Boulia boomerang and wear shell pendants from Carpentaria and Kimberley‘ (Griffiths, 47-48).

Trade had a cultural and social importance, as Mowaljarlai and Malnic (1993) write:
‘The lines are the way the history stories travelled along the trade routes. They are all interconnected. It’s the pattern of the sharing system.’ - [See Map Link Below]

Some goods had a social value that meant they were traded particularly widely. Pearl shells from the Kimberley coast have been believed to have travelled at least 800 kilometres away from their point of origin; with some claiming that they reached as far as the mallee, in western Victoria and eastern South Australia. Some pearl shells were as wide as a small plate, engraved with patterns and worn as a pendant by powerful men.

Stone axes also spread over vast distances. At Calingorady Creek (Moore Creek), near Tamworth, New South Wales, an outcrop of greywacke running along the crest of a saddleback ridge was mined prolifically for over 100 metres. In the 1960s, McBryde used petrological analysis – which had previously been used to show that the bluestone used in building England’s Stonehenge had come from Pembrokeshire, Wales – to examine 517 stone axes that had been scattered across New South Wales. They found that rock from the quarry near Tamworth had been carried as far as Cobar, Bourke, Wilcannia and other parts of western New South Wales – a journey equal to that between Belgium and the south of Spain (Blainey, 191-192).

Ochre was another commodity which was traded widely. Red ochre was particularly important to First Nations peoples across Australia: it was used to adorn the body during ceremonies, decorate wooden implements, and in rock art. The ochre trade is particularly ancient: Mungo Man, the 40, 000 year old ritual burial found in the Willandra Lakes area of Western New South Wales, the traditional meeting place of the Muthi Muthi, Nyiampaar and Barkinji Aboriginal tribes, was covered in over two kilograms of red ochre. The ochre had been brought over 200 kilometres to the burial site (Griffiths, 131).

The first material to be mined in the Flinders Ranges, South Australia, was not copper or gold but red ochre. Ochre from a quarry east of Parachilna township, known as Bookatoo, was celebrated among the Dieri people of central Australia. It was regarded as being of an exceptionally high quality, and held a spiritual importance, believed to be the blood of a sacred emu. The Dieri would send armed bands of 70-80 men 500 kilometres to the south to barter with the traditional owners of the mine, the Adnyamathanha people – even though there were plenty of more accessible ochre mines, such as the Ochre Cliffs near Lyndhurst on the Strzelecki Track.

It is also likely that the Dieri people used their access to the prized ochre to trade for pituri, a psychoactive drug made from the leaves of duboisia hopwoodii, used as both a painkiller and stimulant. The most prized variety of pituri comes from near Bedourie in western Queensland, which was traded north to the Gulf of Carpentaria and south as far as Kurdnatta (Port Augusta South Australia). It is said that pituri provided the one solace for Burke and Wills, slowly dying in remote Central Australia in 1861 (Flood, 202).

The act of trade had a cultural importance; taking on ritual and ceremonial aspects. It shaped the way that landscapes were understood. Particular localities became associated with particular manufactured goods, as different groups made objects with skill that was admired elsewhere. This specialisation was the basis of trade. So, for instance, groups living near Mparntwe (Alice Springs region) were particularly admired for skill in making wooden bowls used for liquids. Specialisation was a source of identity, often expressed through local mythologies (Blainey, 194).

The extensive travel that trade required meant that Aboriginal people had a vast knowledge of the world in which they lived, far beyond their direct locality. They used knowledge of the stars to guide them on long journeys; and had understandings of places that they did not have direct experience of. Early West Australian settler George Moore observed that ‘the natives are all aware that [Australia] is an island’. In 1840, men near Fowler’s Bay, South Australia, correctly assured Edward John Eyre that there was no inland sea; while Sturt recalled that Toonda, his guide in 1844, was able to accurately draw a plan of the Murray-Darling river system.

Aboriginal people studied the world that surrounded them, exchanging long-distance visits to learn of far-away lands and skills. Songs and ceremonies, holding practical knowledge needed for survival and navigation of the land, travelled thousands of kilometres in a short period along what is known as Songlines.

Anthropologists were astounded, for example, when Aboriginal women in Kurdnatta (Port Augusta), South Australia, accurately provided details of places in a song series describing Mparntwe (Alice Springs region), 1200km away. They were able to trace the trading of the ceremony, songs, stories, dances and art back to Mparntwe via the outback South Australian town of Utnadata (Oodnadatta).

This trading of songs can be thought of as a trading of intellectual property to assist travelling. Aboriginal people travelled a lot. They renewed and created relationships and socialised at small ceremonies and huge gatherings. They travelled for seasonal harvests on land, in rivers or at sea, either seeking or avoiding dominant weather events. If you knew the songs, you held knowledge of the land to aid navigation as well as find water and food resources.

Trade also necessitated linguistic dexterity, as Walter Roth, the ‘Aboriginal protector’ of Northern Queensland, recalls:

Picked men may be sent to a distant tribe just for the sake of learning [a dance] … It may thus come to pass, and almost invariably does, that a tribe will learn and sing by rote whole corrobborees [sic] in a language absolutely remote from its own.

Though there was no common language across the continent, there was extensive contact between different language groups. Children frequently had parents who spoke different languages. People spoke up to three or four languages, and some could understand several more; making Aboriginal Australians among the world’s most multilingual people. Such multilingualism is still common today, with people in Arnhem Land frequently speaking English as a third (or thirteenth!) language.

Dialect chains enabled long-distance communication. For example, Group A was able to understand Group B, who understood Group C, but Group A might not have been able to understand Group C (Flood, 173). In Central Queensland and the Western Desert, these chains extended over 3000 kilometres.

THE PANARAMITEE ROCK ART TRADITION: MARKINGS IN THE LAND

The extent of cultural exchange between Aboriginal groups is indicated by the widespread Panaramitee rock art style – also known as ‘track and circle’ – which is found across mainland Australia and Tasmania.

The style was 'discovered' by Bob Edwards, an amateur field photographer on a survey of north-east South Australia with his mentor, Charles Mountford. One of their starting points was the series of engravings found at Panaramitee Station.

Moving from station to station, they found over a thousand similar pieces of art, depicting animal tracks and circles, and less frequently crescents, human footprints, radiating lines, and other nonfigurative designs. These same motifs appeared in a number of sites.

Early European explorers had believed the engravings to be fossil footprints, or the result of algae and lichens eating into rock. But it was clear that they were human markings, formed by pecking with a stone hammer into the rock, which were then covered by ‘desert varnish’, a shiny, rust-coloured accretion that builds up over a long period of time. Mountford believed that the varnish was evidence that the carvings were extremely old, confirmed by his interviews with Aboriginal elders, who claimed that the engravings ‘had always been there.’

As Edwards and Mountford ended their survey, the rains hit, filling rockholes and causing creeks to flow. This stroke of good luck revealed to them another continuity of the engravings: each was next to a waterhole, or other form of supply.

Over the following three years, Edwards collected instances of this style across South Australia and the arid centre of Australia, virtually all associated with water sources and arid camp sites. He had uncovered what archaeologists call a ‘stylistic unit’, the artistic signature of an ancient, widespread cultural tradition. The consistency of the drawings led him to believe that these motifs predated ‘the time when tribal boundaries became rigid and separate cultural entities developed.’

In 1966, as part of a team of researchers led by John Mulvaney, Edwards uncovered tracks and grooves resembling the Panaramitee engravings, at a site west of Katherine, in the Northern Territory. They were able to date the engravings at 5000-7000 years old, the first such dating of rock art in Australian history, proving Edwards’ argument that the style was ancient.

In 1974, the archaeologist Lesley Maynard studied engravings in Laura in Queensland, Mount Cameron West in Tasmania, and Ingaladdi in the Northern Territory, each of which she believed to be part of the Panaramitee style. The Tasmanian find was particularly important, indicating that the style developed before the creation of the Bass Strait by rising seas at the end of the Ice Age.

This led her to develop a chronology of Australian rock art. The first was ancient ‘deep cave art’, produced in the last Ice Age; then the homogenous and widely distributed forms of the Panaramitee, also dating to the Pleistocene (Ice Age); and finally the regionally diverse styles of the Holocene (post-Ice Age), both ‘simple figurative styles’, and ‘complex figurative styles’, including the striking Wandjina of the Kimberley, and the intricate X-ray art found in Arnhem Land and Kakadu.

Maynard’s chronology has since been challenged by other archaeologists, including Andrée Rosenfeld, who has argued for greater cultural difference between North Queensland styles and those found in the ‘red centre’. Others have challenged the antiquity of Panaramitee style, suggesting that many of the tracks do not actually date back to the Pleistocene. Many of the artworks found in the central deserts of Australia are of much more recent origin, indicating a continuation of the style into recent years across a large part of Australia (Griffiths, 174-199).

TRADE IN SOUTH-EAST AUSTRALIA:

The trade of Aboriginal peoples in south-east Australia (southern New South Wales and Victoria) has been extensively studied by Isabel McBryde.

In particular, greenstone axes produced at the Mount William Stone Hatchet Quarry (known as Wil-im-ee Moor-ring), on the outskirts of Melbourne, were revealed by McBryde to have travelled over 1000 kilometres across southern Australia. The quarry today, listed as a National Heritage Place, bears the scars of thousands of years of mining by the traditional owners, the Wurundjeri. Deep pits were dug to reach unweathered stone; and the surface of boulders were heated to break away pieces of rock. The heads were then shaped using a large boulder as an anvil, which were then shaped further by their new owners.

Though the whole tribe had an interest in the place, it was under the special custodianship of one man (in the 19th century, a man named Billibellary), who had inherited this from his father, and traded stone for weapons, rugs and ornaments. In one instance, a visitor exchanged a possum-skin rug for three pieces of the stone (McBryde, 148). It seems to have supported a sedentary population: one settler described thirteen ‘warm and well constructed huts’ near Mount William (Gammage, 300).

Stone from the quarry reached the numerous groups of the Murray River, as far away as Yelta (near Mildura). Early settler Isaac Batey was told in 1862 by an Aboriginal stockman from the Lachlan River, New South Wales, that stone for hatchet heads came ‘from a hill down in the Melbourne country’ (McBryde, 133), while the stone also reached Guichen Bay, near Mount Gambier, South Australia.

In turn, the people of the Murray produced goods from the roots of kumpung river grass. Twine was made by twisting fibre, which was used for fishing line; bags, belts and headbands; for binding axe heads; and for ritual purposes. It was also knotted into nets, used to fish and catch emu, ducks, and small animals. Each group needed around thirty-five kilometres of raw twine to have a set of nets, which meant that twelve kilometres of twine had to be manufactured each year. In total, the process of creating a net took around a year of 35-hour weeks. The work of preparing twine and smaller nets was done primarily by women, while men worked on the larger nets. Much like in pre-industrial England, work was cooperative and social, as people sat around, gossiped, and told stories while producing objects.

Great trading meetings were held on the Murray River. These festivities were often tied to particular food harvests, such as the collection of taarp (lerp), a carbohydrate secreted on eucalypt leaves by plant-eating insects, prized for its sugary taste.

The eel harvest of the Budj Bim Cultural Landscape – a sophisticated aquaculture system that is believed to have supported a sedentary population – was another major festivity, which attracted people from as far away as New South Wales and South Australia to feast on smoked eels caught in the traps. The Brewarrina Fish Traps of northern New South Wales were also host to one of Eastern Australia’s great festivities, with huge numbers of people coming to partake of the harvest, with fish complimented by flour-based breads.

PATTERNS OF EXCHANGE IN ARNHEM LAND:

At the other end of Australia, the trading and exchange patterns of the people of Arnhem Land have also been extensively studied. Thanks to challenging tropical conditions and the fierce resistance of the local Yolngu people, Arnhem Land was never conquered or systematically settled by British colonisation. For the British, its history is a series of failed military, pastoral and mining settlements. As a result, traditional Yolngu life patterns have remained strong to this day.

In the 1930s, the anthropologist Donald Thompson studied the trading patterns of the Yolngu people extensively. Thompson found that every individual in Arnhem Land was a part of a ‘great ceremonial exchange cycle’. A man on the Lower Glyde River, for example, would have received black pounding stones from the east; possum fur, dillybags and spearheads from the south-east; boomerangs, hooked spears and ceremonial belts from the southwest; heavy fighting-clubs from the north-west; and foreign goods (traded by Macassan sailors) from the coastal north-east, calico, blankets, tobacco, knives and glass, much of which he traded away in further exchanges.

FISHING

This exchange cycle was at the heart of Arnhem Land culture: each individual was under a social obligation to send gifts to partners in remote areas. The act of giving gave esteem, while slowness and a lack of generosity in giving earned disapproval, even social ostracism.

Unlike trade elsewhere in pre-settlement Australia (with the exception of the trade between Cape York, the Torres Strait Islands, and Papua New Guinea), Arnhem Land formed part of a truly international network of exchange. For centuries fishermen and voyagers from Makassar, a city on Indonesia’s Sulawesi island, searched the shores of Arnhem Land in search of trepang, a sea cucumber prized as a delicacy in China.

Anthropologist Campbell Macknight suggested that the trade began between 1650 and 1750, while later scholars such as Darrell Lewis and Anne Clarke have argued that the Macassans started visiting much earlier, around 1000 years ago. The trade only came to an end in 1907, outlawed by the brand-new Australian government.

While on the shores of Arnhem Land, the Macassans grew rice, built stone hearths, and traded with the local Yolngu community, exchanging tobacco, pipes, beads, belts, cloth, iron knives and axeheads and strong dugout canoes, known as lippa-lippa, for the right to fish on Australian waters and employ local labour. They introduced new technologies, such as the dug-out canoe, and inspired a shift in diet to one including more seafood. Macassan words entered the local languages, and some Yolngu people even spent time in the city of Makassar.

The Makassars were integrated into the global trade network, passing goods on to China and using Dutch coins (thanks to Dutch colonisation in Indonesia). The extent of global connection to Arnhem Land is displayed by the mystery of a 12th century African coin found by a serviceman during World War Two.

Macassan goods travelled widely in Australia, even down to the ‘red centre’: botanist Christopher Giles found in a rainmaker’s bag by the Finke River, in central Australia, ‘a curious examples of extremes meeting’, pearl shells obtained from ‘the Malays’ and a boy’s marble from Adelaide.

THE BODY OF AUSTRALIA: A CONNECTED CONTINENT:

Evidence of the trade routes in Aboriginal Australia indicates that Australia was a network of peoples ‘economically integrated’ by the Dreaming. Ngarinyin lawnan David Mowaljarlai, the late elder of the Kimberley, Western Australia, detailed the interconnectedness of Aboriginal people in his map Bandaiyan, Corpus Australis (The Body of Australia) - [See Map Link below].

On his map the whole continent and its islands are joined in a single grid system of social and spiritual connections. The diamonds within the pattern are communities of Aboriginals and the lines connecting them the ancient trade routes and Dreaming pathways that Mowaljarlai calls ‘landstories’. At the nodes connecting the lines is concentrated knowledge – sites of significance or ‘story places’ in which knowledge is embedded. Corpus Australis represents the country as connected through these nodes in the sharing of resources and technology over millennia.

The map of Australia is remapped by Mowaljarlai as a map of the human body, with the line from the Gulf of Caprentariria to the Great Australian Bight the spinal column on which the body is constructed. Cape York and Anhrem Lands constitutes the lungs, Uluru the bellybutton, the Great Australian Bight the public sections, and the southern offshore islands the feet.

For Aboriginal people, society, the environment, and the individual person are not separate from each other. Rather they are united in what the author Mudrooroo describes as “the unity of the people with natural and all living creatures and life forms”. Life and land are intimately connected in a vast network interwoven across vast landscapes.

Many of the most successful exploits of settlers and explorers was thanks to their making use of older Aboriginal trade routes. John McDouall Stuart, the first European to cross the Australian continent, followed an Aboriginal route that led traders from spring to spring in the harsh South Australian outback, linking Cape York and the Kimberley to the southern coast. This route was used in the 1870s to establish the Australian Overland Telegraph Line, connecting Port Augusta to Darwin, with the help of camels and camelmen from the Middle East and Asia.

The route was later used by camel trains led by ‘Afghan’ cameleers to haul goods into central Australia and formed the base of the Great Northern Railway, known as the Ghan, which closed in 1980.

Similarly, the cattle thief and bushman, Harry Reardon, was able to successfully transport 1200 head of stolen cattle from Bowen Downs Station, 130 kilometres north of Longreach, 1000 kilometres south to Hill Hill Station, South Australia, thanks to his communication with Aboriginal people, which allowed him to navigate the desert successfully. The route he established from Lyndhurst to Innamincka was one long traversed by Aboriginal traders, who transported red ochre from the Ochre Cliffs near Lyndhurst north to the Gulf of Carpentaria and south to the Southern Ocean, today known as the Strzelecki Track.

The town of Halls Creek, Western Australia, was an important place of exchange for the traditional owners, the Jaru and Kija people, thanks to its location on the trading routes stretching from the centre of Australia to the Kimberley coast. Even in the cities, many of today’s major landmark have long been ceremonial gathering places for Aboriginal people, including the Melbourne Cricket Ground and King’s Park, Perth.

Ancient news roundup

Africa (Olduvai Gorge):

Research suggests that early man (c. 2 million years ago) was able to manage in a changing environment for 200,000 years. 

'The findings uncovered at Oldupai Gorge and across eastern Africa indicate that early human movements across and out of Africa were possible by 2 million years ago, as hominins possessed the behavioural ability to expand into novel ecosystems.' 

Part of this may be due to the use of stone tools, technology which (it is speculated) may have been employed by other hominin species such as australopithecines:

'... we know that the genus Paranthropus was present in Oldupai Gorge at this time.'

Tibet:

DNA from the hominin species knows as Denisovans has been found in sediment in Baishiya Karst Cave on the Tibetan plateau - the first such find outside Siberia. The specimens date from c. 100,000 years ago, again from 60,000 years ago, and possibly also 50k-30k ya; in the latter case that may have overlapped with the arrival of modern humans and interbreeding there or elsewhere could explain why 'present-day Tibetans carry a gene variant that aids high-altitude survival'.

Conflict between Homo Sapiens and the Neanderthals

An academic at Bath University suggests there was a 100,000-year war between the two species that pitched modern humans against the Neanderthals that had preceded them out of Africa and were already thriving in Europe and Asia:
South Africa

Article on early man in southern South Africa 200,000 years ago, when sea levels were lower - the hunting grounds since partially inundated following the end of the Ice Age:

It seems prehistoric women could be hunters, as well as gatherers:

Dogs and humans

Parallel DNA research into human and canine genomes is sketching an 11,000-year-long (or more) history of their relationship. The five separate dog genomes have expanded to 32:

https://www.sciencemag.org/news/2020/10/how-dogs-tracked-their-humans-across-ancient-world

Dingoes, on the other hand, seem to have arrived in western Australia some 3,500 years ago - far later than humans - and although some were recorded living with aboriginals in 1788 they don't feature much in ancient rock art; perhaps for roving hunter-gatherers dingoes were an unaffordable luxury?

MADAGASCAR: Ancient site threatened by climate change



The Conversation reports the threat to African heritage sites posed by climate change:
https://theconversation.com/these-african-world-heritage-sites-are-under-threat-from-climate-change-144140

'Villages and towns associated with the historic Swahili Indian Ocean trading networks are all forecast to suffer significant loss from sea-level rise and coastal erosion in the coming decades...

'A host of unique heritage locations are built on coral, sand or mud – all at elevations less than 10 metres above sea level.'

Among these sites is Mahilaka, the first major urban center and trading port in Madagascar, which was settled by Austronesians in the first millennium CE. Mahilaka is on the northwest coast. Archaelogical evidence is in the form of human artefacts, but also crop species not native to Africa, and maybe even linguistic traces in the Bantu language. There are indications that the neighbouring Comoros islands may have shared some of this Pacific (among others) immigration history.

ORIGINS: Another unknown ancestor in the human bloodline?

New human genetic research has found traces of a mystery hominin that mated with homo sapiens in Africa a million years ago, long before the first wave of our species left for Europe.
https://www.livescience.com/mystery-ancestor-mated-with-humans.html

It's also thought that our ancestors mated with Neanderthals before that first wave of emigrants, which then either died out or returned to Africa; then some of the second wave (c. 50,000 years ago) also mingled with Neanderthals; and later, in Southeast Asia, also mated with 'Denisovans' and another unknown species, possibly more.

'History is made in bed,' as they say.

TAIWAN, bridge to the Pacific islands; and the multiple impacts of climate change

Aside from archaeological finds, there are several other threads connecting prehistoric Taiwan with the spread of humans through the Pacific island chains.

One is the paper mulberry tree, native to Taiwan and Japan, which the Austronesian migrants took with them because they used its fibrous bark to make their cloth. A 2015 study of its genes supports the hypothesis that the species in Oceania are descended from those in Asia.
  https://raskisimani.files.wordpress.com/2013/01/broussonetia-paper-mulberry.pdf
  https://taiwantoday.tw/news.php?post=26541&unit=20%2C29%2C35&unitname=Taiwan-Review&postname=Austronesian-Roots&fbclid=IwAR0rEsePB0aR71MtPstwKguoqx-ZFsHNlw9r5JM0N0h1PbGW1kfIk849PF4

Another is linguistics. Professor Robert Blust https://en.wikipedia.org/wiki/Robert_Blust sorts the many languages of Taiwan into ten groups, only one of which (Malayo-Polynesian) developed into the Austronesian family of tongues.
  https://en.wikipedia.org/wiki/Austronesian_languages#Blust_(1999)
  https://en.wikipedia.org/wiki/Malayo-Polynesian_languages#Major_languages

A third is the study of human genes. A 2014 study of mitochondrial DNA from a c. 8,000-year-old skeleton unearthed on an island off the Chinese mainland links China to Taiwan and Austronesia.
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3951936/

Figure 1: The Liangdao Man Skeleton (picture from here)
The same study suggests a prehistoric migration route as illustrated below, from an area where foxtail millet began to be cultivated (around what is now modern Beijing), to the region where rice was domesticated (surrounding modern Shanghai), to what is now Fuzhou on the mainland (1), on to Liangdao island (2), across to Taiwan (3) and then down to the Philippines (4) and beyond:


(Ibid., adapted from Figure 5)

How did these humans cross over from the mainland? At its narrowest, the Taiwan Strait is about 130 kilometres (80 miles) between Fujian and Taiwan.

Things were different in the last Ice Age. The Strait is now some 100 metres deep, but:
'Pleistocene glaciations lowered [the] sea level 140m in the East China Sea 15,000 years ago, forming a land bridge between Taiwan and the mainland, with Palaeolithic artifacts on both sides. In the initial Holocene 10,000 years ago, melting ice raised the East China Sea 100m, quickly forming the Taiwan Strait.' 
- from 'The Neolithic Taiwan Strait', by Kuang-chih Chang (1989)
https://web.archive.org/web/20120418153210/http://http-server.carleton.ca/~bgordon/Rice/papers/App.18ChangKC89.pdf

'Permafrost covered Asia as far south as Beijing,' says Wikipedia, so perhaps early humans were motivated to go further south, and some willing and able to walk over the exposed land between China and Taiwan.
https://en.wikipedia.org/wiki/Last_Glacial_Maximum#Asia

The end of the Ice Age saw rising sea levels: 'After the last ice age about 20,000 years ago, sea level initially rose due to the melting of the glaciers. That peaked around 4,000 to 5,000 years ago,' says geologist Chip Fletcher in this 2017 interview:
https://e360.yale.edu/features/as-seas-rise-tropical-pacific-islands-face-a-perfect-storm

One might think that this flooding was a spur to the development of boats, but although the earliest found by archaeological excavation date back 7,000 - 10,000 years, other evidence suggests that they existed tens of thousands of years earlier.
https://en.wikipedia.org/wiki/Boat#History
Indeed, recent finds in Central America suggest that homo sapiens may have arrived by sea 20,000 - 30,000 years ago and spread north and south from there, rather than coming though the Alaskan/Canadian ice corridor as previously thought:
http://polynesiantimes.blogspot.com/2020/07/origins-americas-first-colonised-in.html

Contrary to what one might assume, the post-glacial flooding was not uniform in all times and places. As the vast weight of ice was lifted from the land the continental plates started to shift about and rise up further from the Earth's mantle, like a ship being emptied of cargo. 'At the same time that Polynesians were undergoing their journeys of exploration and discovery, 1,000 to 3,000 years ago, sea level was falling and exposing coastal plains that then became habitable, where previously the sea was up against clay banks or cliffs,' says Fletcher. 'In the Pacific region [after c. 4,000-5,000 years ago], sea level started to fall until a few centuries ago. And now global warming is causing sea levels to rise again.'

Although falling sea levels may have made it easier to land boats, 'around AD 1300 there was rapid global cooling, which was followed shortly by rapid sea-level fall – perhaps as much as 50-70 cm within 100 years in the Pacific [...]
   'In almost every island group in the Pacific - from Solomon Islands and Fiji in the west to Rapa and Easter Island in the east – the first signs of collapse appear around AD 1300 with almost all hill forts beginning to be occupied around AD 1400. [...] 
   'Rapid sea-level fall along Pacific island coasts would have lowered coastal water tables, slowed water circulation within lagoons and killed (through exposure) the most productive parts of coral reefs. A food crisis would have resulted for coastal dwellers. Conflict followed. So people fled inland where they stayed, more or less, for several hundred years.'

So the interaction between geography, climate and human history is unexpectedly complex.

NEANDERTHALS: Fact sheet, genetic contribution to melanesians

https://www.express.co.uk/news/world/1315924/archaeology-history-news-ancient-humans-science-news-paleolithic-france-spt
The graphic above is from a recent article in the Daily Express, reporting on Old Stone Age humanoid remains and cave art found in central France:
https://www.express.co.uk/news/world/1315924/archaeology-history-news-ancient-humans-science-news-paleolithic-france-spt

The illustrated geographical range obviously leaves gaps to be filled in, and there seems to be evidence of interbreeding during the upper Palaeolithic between Neanderthals, homo sapiens and 'Denisovans' https://en.wikipedia.org/wiki/Interbreeding_between_archaic_and_modern_humans:

So to some extent the genes of Homo Neanderthalensis' descendants are also represented in the Pacific region:

'Some recent studies suggest that all humans outside of Africa have inherited some genes from Neanderthals, and that Melanesians are the only known modern humans whose prehistoric ancestors interbred with the Denisova hominin, sharing 4%–6% of their genome with this ancient cousin of the Neanderthal,' says Wikipedia https://en.wikipedia.org/wiki/Melanesians.

ORIGINS: Americas first colonised in Central America, NOT across the Bering Strait?

Recent archaeological discoveries in Mexico and Brazil put the arrival of humans there back to 20,000 - 30,000 years ago, when the land corridor through what is now Alaska/Canada was blocked by ice https://www.nature.com/articles/d41586-020-02137-3 :

In a book published last year, British writer on ancient mysteries Graham Hancock theorises that the history goes back much further, by around another 100,000 years:

Perhaps Thor Heyerdahl was on the right track when he built Ra and Ra II to show that a papyrus boat could sail from Africa to the Americas - though why not a Polynesian type outrigger?

TAIWAN: Pacific migration and the paperbark tree

'New evidence gleaned from the study of a common plant species lends further credence to the theory that Taiwan is the ancestral homeland of the Austronesian-speaking peoples,' says this 2015 article in Taiwan Today reporting on research that links Taiwan to a tree now found across the Pacific, the paper mulberry, used to make tapa cloth.



So on their skilled and dangerous voyages across the ocean, the Austronesian migrants must have taken not just food, tools and domestic animals but seeds and cuttings of the precious tree.

MADAGASCAR: How (why) did Austronesians come to Madagascar?

The eastward migration - taking place around the year 500, it is thought - is a mystery:

'One can only assume that the island of Madagascar played an important role in trade, particularly that of spice trade (especially the cinnamon) and timber between Southeast Asia and Middle East, directly or through the African coast and Madagascar.'

FRENCH POLYNESIA: C13th Polynesians migrated east, Colombians west, met in French Polynesia?

'After a detailed DNA analysis of the genomes of more than 800 Polynesians and Native Americans, both modern and prehistoric, researchers have found evidence of contact between the two groups as far back as 1200 CE...

"Our analyses suggest strongly that a single contact event occurred in eastern Polynesia, before the settlement of Rapa Nui, between Polynesian individuals and a Native American group most closely related to the indigenous inhabitants of present-day Colombia," the researchers explain in their paper.

The common ancestors of the humanoids known as Neanderthals and Denisovans spread across Europe and Asia over half a million years ago, and split into the two branches, with fossils of Neanderthals found in western countries and of Denisovans in the East. What is thought to have been the first wave of Homo Sapiens came from Africa c. 270,000 years ago and some may have mated with Neanderthals.

ORIGINS: DNA evidence points to another unknown hominid population in Africa

https://theconversation.com/early-humans-in-africa-may-have-interbred-with-a-mysterious-extinct-species-new-research-131699

'A 2017 study of ancient DNA from southern Africa investigated 16 ancient genomes from people alive over the last 10,000 years. This showed that the history of African populations was complex. There wasn’t just a single group of humans around in Africa when they expanded out 100,000 years ago.

It’s a result that was supported earlier this year by a paper examining ancient DNA from four individuals from what is now Cameroon. Taken together, this research suggests there were geographically diverse groups in Africa well before the main expansion out of the continent. And many of these groups will have contributed to the ancestry of people alive in Africa today. [...]

The new paper provides evidence that there may also have been gene-flow into the ancestors of West Africans directly from a mysterious archaic hominin. [...]

Interestingly, they suggest that 6%-7% of the genomes of West Africans is archaic in origin. But this archaic ancestry wasn’t Neanderthal or Denisovan. Their model suggested the additional ancestry came from an archaic population for which we don’t currently have a genome.

This ghost population likely split from the ancestors of humans and Neanderthals between 360,000 and 1.02 million years ago. That was well before the gene-flow event that brought Neanderthal DNA back into West Africa around 43,000 years ago – although the value of this could be anywhere between 0 and 124,000 years ago.'

ORIGINS: Walking protohumans started in Europe?

According to research published in Nature, the first bipedal ancestor of modern humans may have come from southern Europe. Dubbed Danuvius Guggenmosi, the remains were found in Bavaria and date from c. 11.5 million years ago.

Only a few weeks before this discovery, another research team speculated that a 10-million-year-old pelvis belonging to another species called Rudapithecus Hungaricus may have enabled it to walk upright, too.

https://www.nature.com/articles/d41586-019-03418-2

Before now, says the Daily Mail's report, the earliest evidence of two-legged hominids came from Kenya - the 6 million-year-old remains of Orrorin Tugenensis -  and some fossilised footprints on the island of Crete.

"The discovery of Danuvius may shatter the prevailing notion of how bipedalism evolved: that perhaps 6 million years ago in East Africa a chimpanzee-like ancestor started to walk on two legs after environmental changes created open landscapes and savannahs where forests once dominated."

https://www.dailymail.co.uk/wires/reuters/article-7658067/Prehistoric-ape-Germany-pioneer-two-legged-walking.html

So rather than coming from Africa, it's possible that some of humanity's ancestors may have gone there before re-migrating northwards.

AUSTRALIA: Walkabout to Wave Hill

Our ramble begins with an internet writer's reference to an Australian comedy book from the Seventies, The Outcasts Of Foolgarah. Surfing the reviews, I came across a Depression-era larrikin Oz classic, Here's Luck, by journo and rake Lennie Lower, which is now making us laugh.

But Outcasts, by Frank Hardy, was far from the author's most significant work. His most notorious was one that got him in court for criminal libel - the last case of its kind in Victoria; but that's not where this journey leads us. The experiences of the Depression that gave Lower his comic material had radicalised Hardy, as they did so many others, prompting him to join the Communist Party and use his talents to fight the Establishment.

We have since learned what Communism did; but the instincts that it exploited - compassion for the poor, and vicarious indignation - are valid. In our secular age, they inform ecological panic and adolescent self-loathing, an opportunity for ostentatious do-gooders to secure bossy, well-upholstered sinecures for themselves.

In Australia, they take us to the aboriginals.

Twenty thousand years before Neanderthals recolonised an unpeopled Ice Age Britain, forty thousand before modern man supplanted them in Europe, even longer before humans saw the Americas, the first Australians came to their island continent. Early agriculture? The cities of China and Mesopotamia, Egypt and Mohenjo Daro, the stones of Wiltshire and Giza? Last week's news.

For them, time had no meaning, as is so with all of us, our past always fading into dream, driving us to build, write, record images; futile attempts to preserve our intangible selves in something that endures forever, though nothing will.

Where are their monuments? In their minds, and in their tongues. In their myths of creation and arrival, in the songman's store of rhymes that give life-saving directions for nomads in a pitiless land; an inconceivably long heirloom of songs, some maybe stretching back to the birth of language itself. Old to young, old to young, the chain continued, handing on words and skills that gave them their law and culture; the policeman and warrior, the getter of food and drink, the builder of shelters contained in their skins and carried within their hands and brains wherever they went.

Until the last link broke.

Dispossession, displacement, disrespect; opium via the Oriental trading in Port Darwin; alcohol everywhere, ruining the young as it did their counterparts in America, where sometimes crazy-drunk First Nation kids hang out of cars as they tear around settlement lands which they cannot sell or mortgage.

Instead of the remorseless pressure of daily survival, jobs: money, enough to get by and for some, to dream the modern dreams of easy intoxication. And since the young stopped listening to the old, the elders (some, at least) shut their lips. One by one, the guiding stars of the aboriginal are winking out of existence, taking their knowledge with them.

Materially, a little is done to compensate material wrongs, some in response to action by the victims themselves. Following a walkout in 1966 by mistreated Gurindji aboriginal workers at the vast Wave Hill cattle station, a small portion of their traditional lands were eventually restored to them, and the law has begun to address past injustices. Frank Hardy helped to publicise the issues in his book The Unlucky Australians, and a TV documentary followed.

What can make up for the vast, invisible vandalism of an ancient way of life? Like all humanity, the original Australians have always known war and crime, but what they carried in them was no less precious and far older than the historical relics over which we wonder and grieve in museums.

Still, many times older is the history of humanoids written into all our genes, itself dwarfed by the general relay of life that began billions of years ago. It is fleeting life that endures.
