Re: New article
Interesting indeed Coyote,
In particular I find this interesting
quote:
Following the first Denisova results, I speculated that this mtDNA might be from a late-surviving heidelbergensis living in Siberia.’
So, in Europe, H. heidelbergensis gave rise to Neanderthals, in Africa they gave rise to us (modern humans), and in Asia, perhaps to the Denisovans.
And one of the issues that comes to my mind in regard to:
quote:
‘If the populations were very small, that component [5% Denisovan genes] might represent as few as 50 Denisovans mixing with 1000 pre-Melanesians, but it was sufficient to give the present-day inhabitants of places like New Guinea and Bougainville as much as 8% archaic genes - a small Neanderthal component they acquired first, probably in western Asia, and an additional Denisovan component they acquired later, on their long journey towards Melanesia.
... is that what we could be seeing is the occasional fertility of hybrids as occurs with horses, mules and zebras.
Enjoy
