Question 4

Proposes that anatomically modern humans arose in Africa, migrated out of Africa and replaced any and all archaic Homo populations in Europe and Asia without any interbreeding

Answer 4

Replacement model

Question 5

What is an issue about the replacement model?

Answer 5

DNA evidence of interbreeding between humans and Neanderthals

Question 6

Proposes that independent populations throughout the world evolved from regional archaic Homo groups to modern homo sapiens all at the same time; gene flow always existed

Answer 6

Regional continuity model

Answer 7

No evidence of modern humans existing in Asia or Europe until 50,000 years ago

Question 8

What is the origin of modern humans?

Answer 8

Answer 15

Within, between

Question 16

True or false: Humans are more genetically identical and homogenous

Answer 16

True

Question 17

Predicts hat genetic distance between populations will increase and geographic distance increases; groups that are closer together are more likely to have gene flow and related to each other
