ANT E101 Lecture Notes - Lecture 31: Genetic Admixture, Denisovan, Sister Group
Document Summary
Neanderthals and modern human co-inhabited in europe for approx 10,000 years. Both species hybridized (demonstrated by dna analysis) Late neanderthals associated with chatelperronian tools, similar to modern human tools. Little is known about their anatomy; only a finger bone and third molar. They hybridized with modern humans, as neanderthals did. Complex relationships between neanderthals, denisovans and modern humans. European and asian populations (but not indigenous african populations) carry 1- Denisovans show genetic admixture with some modern humans in eastern asia. Complex relationships between neanderthals, denisovans, and modern humans. European and asian populations (but not indigenous african populations) carry 1-4% neanderthal dna. Areas of our genome with neanderthal dna: Areas that appear to lack neanderthal dna: Pleistocene hominins represent a single evolving lineage across different regions. Amhs evolved in the context of significant gene flow between regions. Amhs originated in africa and later dispersed to occupy the old world. No egen flow/interbreeding, but replacement of existing hominins.
