Which factor did not contribute to the genetic diversification of the Galápagos Island finches studied by Darwin?
A) Environmental conditions varying among the different islands
B) Most of the islands being sufficiently distant from one another such that movement among their populations was limited
C) The islands being only 100 km from Ecuador, so they received a continual input of new genes from the mainland
D) Occasional migrants to new islands rarely interbreeding with endemic species
E) Over time, the residents of each island developed their own genetic distinctiveness

The fact that the Galápagos Islands were only 100 km from Ecuador and received a continual input of new genes from the mainland would not contribute to the genetic diversification of the Galápagos Island finches studied by Darwin. In fact, this would likely lead to genetic homogenization rather than diversification.
