Charles Darwin did not come up with the Theory of Evolution on this voyage. In fact, his grandfatherErasmus Darwinhad already instilled the idea that species change through time. However, the Galapagos finches helped Darwin solidify his idea ofnatural selection. The favorable adaptations of Darwin'...
The specialization in food made possible by beak evolution has separated the species remarkably. Nesting habits of Darwin's finches are interesting. In most species, the single or mated male builds the nest - in fact, may build as many as eight nests. He displays near his nest, and may ...
He noticed that they were similar to other finches in lots of ways but their beaks were all different shapes. He realised that the different beaks matched the type of food they ate on each island. Finch who ate insects had pointy and skinny beaks so that they could pick up the tiny ...
However, Darwin did not correctly identify some of the birds. He thought that the cactus finch was a blackbird and that the warbler finch was a kind of wren. He also did not carefully note which finches came from which island but was later able to correct his notes from those of others ...
Species-specific epimutations were significantly over-represented in these pathways. Since environmental factors are known to result in heritable changes in the epigenome, it is possible that epigenetic changes contribute to the molecular basis of the evolution of Darwin's finches....
Charles Darwin's theory of evolution and natural selection isn't an idea with holes. It's one of the most solid theories in science. But what exactly is it?

Beaks of Darwin' Finches In 1835, before he had developed his theory of evolution, Charles Darwin collected specimens of 13 previously unknown species of finches from the isolated Galapagos Islands. The Galapagos finches closely resembled a species of finches living on the mainland of South America...

Gould, in particular, helped Darwin understand the divergence between the forms of the finches and the mockingbirds that he found on the different Galapagos islands. They were not variations of finches but rather different species of finches altogether. Gould also told Darwin that he mistook one ...
