Evolution
A finch population on an island is more isolated than Êa finch population in a large forest. ÊThe gene pool of the island population would be more limited than the genetic possibilities of the finch population in the forest. ÊThe island finches would be more likely to pass on specialized genes than the forest finches. the island finches have more spatial isolation the island finches have more geographical isolation
Island finches are specially isolated whereas populations that live in large forests aren't. The island finches will have more gene flow.

A small island in Galapagos can hold a large number of finches due to absence of their natural predators .
The Galapagos Islands. Charles Darwin discovered that the birds on the island, finches, had different beaks. The finch's beak varies from each island to help the finch eat the food they can find on the island
They're birds of the Galapagos Island
That the finches were similar to the ones on the mainland, but had adapted to the island environment.
Geometric isolation of common ancestral species of finches has led to the development of 14 different species of finches in the Galapagos Island due to the concept of diversification.
Darwin wondered if the finches on the Galapagos Islands were an ancester to the mainland finches. It turns out they were, one finch went to the island and its decsandants spead across the island. Geographic isolation caused the gene pools to become isolated and each population adapted to a particular habitat on the Galapagos Islands. Over time all the populations became genotypically different that they do not interbreed. Mating finches look for the beak shape.
