13.    From the information given in the lectures, the Galapagos islands were a potential haven for Darwin to appreciate the subtleties of his theory, because: 


F.         the islands are west of Ecuador, and are, therefore, within the warm waters off the coast of South America.

G.        the islands provided sufficient isolation for small populations of finches etc. to interact rarely with their mainland relatives.

H.             the islands were sparse but provided a more than suitable environment for the finches to live well.  Consequently exaggerating the environmental impact of natural selection.

I.           the islands were lush and provided more than an ample environment for the finch populations to swell, and thus diversify.

15.    The “Founder effect” is thought to give rise to:

B.         the catastrophic effects of alcoholism on human populations.

C.         a significant increase in the allelic content of a population, following a catastrophe

D.         a significant decrease in the number of alleles within a population due to fewer individuals starting off a population with a dramatically diminished gene pool.

E.         an increase in the number of individuals in a population that will be more able to withstand the next catastrophe.

F.                      a significant increase in the allelic frequency within a population due to few individuals starting off a population with a dramatically enhanced gene pool.
