Genetic evidence supports which of the following explanations for the presence of 13
different finch species on the galápagos islands?
a. each of the 13 species was founded by the independent migration of a different species from the mainland to
the islands.
b. many years ago, more than 13 different species of birds migrated to the islands. the current 13 finch species
are the only species that survived.
c. it's not clear based on the dna evidence whether the 13 species arose from a single migration of one species
or multiple migrations of several species from the mainland to the islands.
d. many years ago, a small population of a single finch species migrated to the islands and evolved into the
current 13 species.
