Hw they used certain adaptations to survive. Like a certain beak for eating or different colors for camouflage.
Galapagos finches
The Galapagos Finches are best known for the difference in their beaks and also because they were Charles Darwin's inspiration for the Theory of Evolution.
There are thousands of instances of direct evidence of evolution. The most well-known example is that of Darwin's Finches. These finches were observed through fossil records to have changed over time to adapt to their environment.
Charles Darwin is considered the father of evolution. Darwin's Theory of Evolution came about as a result of his studies of finches on the Galapolous Islands. He published two books, 'The Structure and Distribution of Coral Reefs,' and 'Geological Observations on Volcanic Islands' to establish his theory.
The finches on the Galapagos Islands helped him, as they gave him the basis of his idea of natural selection, which was the backbone of his Theory of Evolution. The birds beaks had altered slightly to enable them to eat the various foods available on their respective islands. This observation then prompted Darwin to extrapolate the data, and say that these small changes could eventually result in a fish turning into a reptile.
He's not known for a theory of evolution. Darwin is.
It is thought that the finches have a common ancestor. Separated on different islands, each island eventually produced different finches.
theory of evolution
The theory of evolution has passed on and is no longer just Darwin's theory and the only crisis in this theory is in the heads of delusional creationists.
Darwin only had one theory of evolution, and he defined it in his book On The Origin of Species.
There is no " theory of evolution " as evolution is a fact. The theory is; the theory of evolution by natural selection and explains much about the fact of evolution. Charles Robert Darwin and Alfred Russel Wallace come up with the theory of evolution by natural selection, though natural selection is a phrase coined by Darwin.
Darwin's theory of evolution was revolutionary.
