common ancestor.
b) humans evolved from chimpanzees.
c) chimpanzees evolved from humans.
d) convergent evolution led to the DNA similarities.

common ancestors.
b) common environments are inhabited by the same
organisms.
c) the islands were originally part of the continent.
d) the island forms and mainland forms are converg-
ing.
e) island forms and mainland forms have identical
gene pools.

homologous to the wing of a bird?
