Document Summary
Dna from a finger bone was analysed and identified as belonging to an archaic human group separate from neandertals and modern humans. They would have had brown eyes, dark skin. Geneticists have discovered denisovan dna in the modern human genome. Represents about 5% of some populations in east asia especially melanesia and aboriginal australian people. They have a different cranial structure compared to other homo"s. Multiregional model (regional continuity) suggests that modern humans evolved in various parts of the old world after homo erectus spread out from africa. erectus spread out from africa. Modern humans emerged in only one location africa. Anatomically modern humans then spread into other areas of the old world replacing premodern humans. Neandertal populations in europe were replaced by modern humans 30,000-40,000 years ago. Chapter 5 has a discussion of the evidence for the origins of anatomically modern humans. The majority of evidence presented in the discussion supports the replacement hypothesis:
