Peopling the New World Arctic

All Paleo-Eskimos represent a single migration pulse from Siberia into the Americas, independent of the Neo-Eskimo Thule people (ancestors of modern-day Inuit) and the related extinct Sadlermiut population. The Siberian Birnirk people were likely cultural and genetic ancestors of modern-day Inuit. Continue reading

Homo floresiensis (hobbit man) did not exist – probably just Down’s syndrome individual

The time-line is simultaneous with the existence of the Denisovans (perhaps a little further north?), with the expansion out of Africarabia and also includes the Toba eruption (74 kyears ago). Of course it is possible that an isolated species survived on an island. But at this time during the glacial period Flores was probably no island but was joined to the mainland.
So my inclination is to go with these conclusions that the Flores bones represent a separate population, but not a separate species, of humans. Continue reading

Beringia was inhabited for 500 generations

The now submerged land bridge (Beringia) between Asia and North America was not just a little strip of land across which the ancestors of native Americans quickly moved across. It was not just a rest stop for the journey to America. The “bridge” was a vast area of land and itself served as a fairly permanent habitat and refuge for ancient humans for around 10,000 years (500 generations) from 25,000 to 15,000 years ago. Continue reading

Promiscuity in the Pleistocene

At some point there must have been children who were 50% Neanderthal and 50% AMH. And some who were 50% Neanderthal and 50% Denisovan. How did they survive? What kind of society existed in these ancient times that would permit such offspring not only to survive but also to mate and produce offspring in their turn? But however it happened, our ancestors in the pleistocene were a promiscuous lot. Continue reading

SE Asia rainforests shaped by humans for 11,000 years

A new study comes to the brave conclusion – based on ancient pollen samples which contain charcoal and and therefore suggest that land was cleared and planted – that the rain forests of SE Asia have been “managed” by humans since about 11,000 years ago! Continue reading

Light skin genes in Europe less than 7,000 years old

The first European genome sequence that predates the appearance of agriculture from skeletons in La Brana show that these hunter gatherers had dark skin and blue eyes. The dark skin is a very interesting finding, as light skin is nearly universal across Europe today. These results suggest that the light skin seen across Europe today is a development of the last at least 7,000 years. Continue reading

Language and tool making use the same area of the brain

The same areas of the brain are activated for language production and making complex tools, supporting the theory that they evolved at the same time. Continue reading

Infanticide in primates but social isolation in mammals led to monogamy

Among primates, including perhaps humans, monogamy evolved because it protected infants from being killed by rival males. But for mammals in general Social monogamy may have evolved where breeding females were intolerant of each other and female density was low as a mating strategy where males were unable to defend access to multiple females. Continue reading

Ancient human dna suggests European /Asian split happened well before 40,000 years ago

DNA analysis of ancient human bones from Tianyuan cave suggests that the major migratory splits between Europeans and Asians happened considerably earlier than 40,000 years ago. Continue reading

Was dog domestication the critical advantage for Sapiens over Neanderthalensis?

Using eyes for communication and the canine ability to read such movements may have provided Homo Sapiens with the ability to domesticate dogs and this in turn may have been a critical factor in the dominance of Sapiens over Neanderthalensis. Continue reading
