Question 7

In Dianne Dodd's experiments with Drosophila pseudoobscura,different populations were established that were raised on diets of either maltose or starch.When flies from the different populations were allowed to mate,some flies mated with flies fed on a different food source,but there was a preference for mating with flies raised on the same food source.What does this phenomenon illustrate about the timescale of speciation?

Question 8

Discuss how the proximal CMT1A repeat that appears near the gene coding for peripheral myelin protein-22 (PMP-22)has been used to examine the phylogenetic relationships between humans,chimpanzees,bonobos,gorillas,orangutans and several other primates,and why this repeat provides evidence that supports the theory of descent with modification and against the theory of special creation.
