He didn't do the study of the Galapagos Finches. The people who studied these birds were biologist Peter Grant and Rosemary Grant. They looked at beak size and shape. The finches are commonly called Darwin's finches, however, they really were not studied by him. They used to finches to study Darwin's Theory of Evolution by Natural Selection. In order for NS to occur there must be variation in a population, variations must be heritable, the species must be reproductively successful, and the survival and reproduction of an individual must be nonrandom. The Grants came up with 4 postulates based on the NS model. 1. Is the finch population variable? 2. Is some off the variation among individuals heritable? 3.Do individuals vary in their reproductive success? 4. Are survival and reproduction nonrandom? The overall conclusion that they made was that: when all four of Darwin's postulates are true in a population, the population will evolve; and that evolution an occur over a short period of time.
Darwin was the scientist that caused controversy that still exists today.
Natural Selection is what Darwin believed was the cause of evolution.

I did it simple... Compare-They both move it. Contrast-They do other things...Like,Wind blows and water flows.
Charles Darwin founded the evolutionary theory, and wrote six books on it, but in the fifth and sixth, said that his logic was wrong, and only after he retired did he regain his sanity, as writing caused him to lose it.

The disaster is the death injury and destruction it caused/. It nearly wiped out the city of Darwin.
Darwin said that if an organisms environment changes, it changes. Ex: A mammal is moved from a warmer forest to a snowy forest, therefore its fur will become longer and thicker.
