Who is Charles Darwin and what his theory took from Galapagos?

The islands appear on a vellum chart, undated, but thought to be from the 1530s, though it is likely that an artist added the islands after its original creation. The first activities of the Station addressed education, invasive species, and endangered species issues identified by the Bowman and Eibl-Eibesfeldt reports. On the Galapagos Islands, Darwin also saw several different types of finch, a different species on each island. He noticed that they all had slightly distinct shapes that made each specific bird fitter for survival on its island. CHARLES DARWINS PROFILE.

Subsequently, US west coast universities and museums began to play an increasingly important role in Galapagos science. Evolutionary Biologists are fascinated by island ecosystems and the clarity with which the species that inhabit them illustrate evolutionary processes.

Quite simply, because animals are mobile, they have always had an advantage over plants in that they could move to more favorable areas on the islands, if such areas existed for them.

Today, scientists study the archipelagos aquatic ecosystems as well. However, San Cristbal was more attractive to colonists because of its relatively easy access to water. Galapagos Islands . The Galapagos were a key whaling area because of the breeding grounds for sperm whales and the deep water feeding areas of the species to the west of the islands.
