Macroevolution

The Galapagos finches are a good example of this phenomenon. It is thought that the variety of finch types developed in order to fit into a variety of habitats.

The success of the finches on the Galapagos was most likely due to the

• large numbers of other birds competing for food

• birds adapting to different niches

• food supplied by humans

• mutations occurring in every offspring
