Evolution Chapter 25 Discussion Questions

DQ 25.1

Why might brain size have increased during human evolution (Fig. 25.11) ? How could alternative hypotheses be distinguished?

DQ 25.2

What is the genetic evidence that archaic Homo, living outside Africa, made a negligible contribution to our ancestry? HINT 25A

DQ 25.3

How could we find the number of genes responsible for uniquely human adaptations?

DQ 25.4

There has been an extensive discussion of whether the FoxP2 gene played a role in the evolution of our linguistic ability (see Web Notes). Summarize the evidence for and against.

DQ 25.5

It has been proposed that the gene ASPM has been responsible for part of the increase in human brain size (see Web Notes). Evaluate the evidence for this claim.
