There are now at least 13 species of finches on the Galapagos Islands, each filling a different niche on different islands. All of them evolved from one ancestral species, which colonized the islands only a few million years ago. This process, whereby species evolve rapidly to exploit empty ecospace, is known as adaptive radiation...The ecological niches exert the selection pressures that push the populations in various directions. On various islands, finch species have become adapted for different diets: seeds, insects, flowers, the blood of seabirds, and leaves. The ancestral finch was a ground-dwelling, seed-eating finch. After the burst of speciation in the Galapagos, a total of 14 species would exist: three species of ground-dwelling seed-eaters; three others living on cactuses and eating seeds; one living in trees and eating seeds; and 7 species of tree-dwelling insect-eaters." pbs (<--- easiest way to cite a source, control-V, cut and paste the link) 1. Explain, in your own words, how a single finch species evolved into different Galapagos finch species. Make sure to use as many terms from Chapter 7 as you can and as always, cite your sources. You do not need to go through all fourteen. You can use just one species and walk us through the process. Make sure to discuss beak shape and diets, adaptations, different environments, and island adaptive radiation. There are many resources on this topic. Take some time to research this topic using multiple sources and then write your impression. Do not just read one article and give me definitions. I hope you are all healthy and happy!
