Be

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.
J.
life
was thought to have begun on these islands.
K.
England
was just too darn cold and wet for Darwin to be able to do any proper field
studies

The
“Founder effect” is thought to give
rise to:
A.
a
significant increase in the survival potential of a population, following a
catastrophe
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.
G.
an
increase in the number of alleles within a population, following a major,
beneficial migration event.
