First wave: h. erectus moved out of africa into asia and europe: heidelbergensis moved into europe and evolved into. Second wave: amhs move into europe and asia, replacing other. Distinct species, did not interbreed with existing hominins. Neandertals hominins: partial replacement model with existing hominins, regional continuity model. Same as complete replacement but they did interbreed. Homo sapiens evolved independentally in all parts of the. Ancestors were hominins who previously occupied these world regions. Study of living people to determine most recent common ancestor (mrca: mitochondrial dna.
