Archaeology ARC 130 Lecture Notes - Lecture 5: Homo Habilis, Homo Floresiensis, Homo Erectus
Document Summary
Improved hunting techniques and more diverse subsistence strategies more diverse array of foods=better survival because can always find food: larger group sizes, more elaborate social networks, neanderthal dna. In 1997, scientists succeeded in extracting dna from a 40,000 year old. Intelligence tools, language, and the control of fire: all other terrestrial primates reduce. The genus homo emerged ion the pleistocene ice age = 2,588,000- Dna segment mutates ~1 base every 25 million years. Environmental contamination from microbes, fungi, etc: amount of neanderthal dna in the sample used to create the initial neanderthal genome sequence was 1. 5-3, vast majority of sample was throwaway bacteria and fungi, clean lab methods. Independent lab verification important test it multiple times, by. Neandertals: human-neandertal differences between human-human and human-chimp, but much closer to human-human, human-neandertal divergence estimated to be about ~660,000 years ago. If because neandertals have gained environmental adaptations in their environment, that will be passed on to first hybrid offspring.
