Only the following statement is true regarding the genetic evidence for interbreeding of early modern humans with older populations:
Modern Eurasian populations contain about 2% Neanderthal DNA.
The other statements have inaccuracies or are false.
– Modern African populations actually carry some traces of Neanderthal DNA, but at very low levels compared to non-African populations.
– Most modern mainland Asian populations contain about 0.2% Denisovan DNA, not 0.5%.
– Modern Pacific populations have been shown to have the highest content of Denisovan DNA, with Melanesians and Aboriginal Australians carrying about 4-6% Denisovan DNA on average.
– Modern European populations have little or no Denisovan DNA, as Denisovans are believed to have lived mainly in Asia.
