Document Summary
. intestinal parasite species predict that humans started eating meat over 1 million years ago. Cranial differences of homo erectus with homo ergaster. Larger brain, brow ridge, no chin, prognathic face in heidelgergensis. 94 thousand years ago, 4 or 5 species were living simultaneously and competing. A group of humans who is thought to be very closely related to neanderthals. Appearance from 127 to 30 thousand years ago in europe and western asia. >some date back as far as 400 thousand years. They lived in a uctuating environment with a cooling trend. Eurasia was frigid grassland and had many large mammals. more robust limbs with better developed muscle attachments. Clothes (body lice diverged from head lice when humans started wearing clothes) Used caves as home bases but no shelters. Approximately 1-4% dna in europeans and asians is shared with ancient neanderthal dna (but not sub-saharan africans) This has been contested and interpreted as hybridization.
