• Java
• Ethiopia
• Israel
• Kenya

Java

4

A sloping of the sides of the skull toward the top is known as:

• 190,000
• 160,000
• 130,000

160,000

6

Evidence of gene flow between archaic and moderns would:
• Case doubt on both the MRE and the AR models
• Refute the MRE model and support the AR model
• Refute the AR model and support the MRE model
• Refute the Primart African Origin model

Refute the AR model and support the MRE model

7

Which of the following is part of the Multiregional Evolution model?
• There must be distinctions between our modern species and archaic humans that clearly distinguish ys as separate species
• Fossil transition between pre-modern and modern humans should occur only in the single region in which moderns evolved
• The physical features we associate with modern humans appeared everywhere but may have been manifested in different ways
• Neanderthals and Homo sapiens should be considered two separate species

The physical features we associate with modern humans appeared everywhere but may have been manifested in different ways

8

Which of the following is part of the African Replacement model?
• Modern looking Homo sapiens spread over the Old World from Africa, replacing archaic populations when they came into contact.
• The degree of species mobility resulted in sufficient gene flow to maintain a single species
• Homo sapiens arose in Africa as much as 2 mya
• Modern human traits do not define and distinguish a new species of hominins

Modern looking Homo sapiens spread over the Old World from Africa, replacing archaic populations when they came into contact.
