Question 7

Charles Darwin used the process of artificial selection during domestication as an analogy to explain natural selection. In what ways are artificial and natural selection similar? In what ways do they differ?

Accepted Answer

They are similar in that both processes

Question 8

If you could protect from extinction only the lineages derived from two of the nodes in the figure, which pair would you save to yield the greatest phylogenetic diversity?

Accepted Answer

A)  Nodes E and F 
B)  Nodes D and E 
C)  Nodes C and D

B)  Nodes D and E 
C)  Nodes C and D 
D)  All of the choices are equivalent.

Question 9

In comparing pairs of genes in the human and chimp genomes, Tarjei Mikkelsen and his colleagues first determined the expected degree of divergence between the two genomes based on the accumulation of neutral mutations. Why is this an important first step in understanding how evolution is occurring in these species?

Accepted Answer

The rate of neutral evolution serves as
