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

Not so random animal sounds may show a stepping stone towards language

The sequence in humans – I speculate – could have been:
(300KYA) gestures>> sounds>> (smiles, laughter?)>> words>> ..(unknown steps)>> simple grammar>> context-free grammar>> language>> symbols>> abstract symbols>> writing (12KYA) Continue reading

Archaeological evidence suggests Neanderthals and AMH overlapped for upto 250 generations

If the interactions at the various locations each spanned 100 to 250 generations – and approximately 2,000 generations ago – it is not difficult to imagine a gradual assimilation and subsequent disappearance of Neanderthals – especially if there was a fertility difference in favour of AMH. There would be no need then to assume catastrophic extinction or genocide of the Neanderthals. An AMH population expanding much more rapidly than a co-existing, socially compatible but declining population of Neanderthals would suffice to explain the 3% or so of Neanderthal genes left in the surviving population today after a further 2,000 generations. 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
