ANTH 122 Final: Final Study Guide - Becoming Human
Document Summary
4-6% of denisovan genes in modern pacific populations. <1% in native americans, siberians, east asians, and. South asians: contributions to modern gene pool, alleles for the immune system, gene for adaptation to high altitude, mtdna, mitochondrial dna, inherited maternally, makes it easier to trace lineages, evidence relating to human origins: Neandertals vs. humans is larger than humans vs. humans. 2: would point to neandertals being a branch species, and although this is comparing. Neandertals to current modern humans, studies on modern human fossils had same results. Neandertal personal ornamentation: human origins models, multiregional model. Expansion of homo ergaster and homo heidelbergensis into eurasia = new environments and evolution of biological features. In contact with other populations and interbreeding: gene flow ensured that hominins remained one evolving species across all areas that they occupied. 3: by 200 kya, homo heidelbergensis evolved into homo sapiens.
