Answer 1

‘out of africa’ theory and ‘multiregional’ theory

Question 2

out of africa theory

Answer 2

homo sp\apiens evolved in africas and then spread around the world, there was no gene flow between the isolated populations. homo spaiens replaced populations of homo erectus and neanderthals that had already moved out of africa, evolution of homo spaiens was independent to homo erectus

Question 3

what supports the out of africa theory

Answer 3

differences between different ancestors and mtDNA analysis from homo spaien fossils supports the common ancestor of all humans 170,000 years ago in africa

Question 4

multiregional theory

Answer 4

homo erectus left africa and spread throughout the world. homo sapiens evolved from homo erectus independently of all other homo erectus populations. there was enough gene flow between the independently evolving populations to all remain one species
