Darwin did an investigation on finches to observe natural selection aka "survival of the fittest" and he examined how the different sized and shaped beaks effected their survival of retriveing food and worms during periods of drought and during normal periods of weather. The amount of food retreived could also predict the amount of offspring of that certain species of finch. Hope it helps! i did a lab experiment on this.
Darwin was interested in the finches! The finches weren't interested in him!
All known species of Darwin's Finches are found on the Galápagos islands. With the exception of one, the Cocos Finch, which is found on the Cocos Island. Darwin's finches are not actually true finches. Darwin knew they weren't finches, but an ornithologist called Percy Lowe, later in 1936 incorrectly called them "Darwin's Finches" in a book, a term which unfortunately stuck.
Charles Darwin discover the finches in Galapagos in 1831. He noticed that the finches beaks were different compared to the finch's in Ecuador.
Galapagos finches
Darwin was puzzled about the many adaptations of the finches on the Galapagos Islands
That they were evoled from on specie of finches.

Darwin's observations of greeter and lesser South American Rheas, in addition to his observations of the Galapagos Island finches, were an integral part of the development of Darwin's evolutionary theory.
no
It is thought that the finches have a common ancestor. Separated on different islands, each island eventually produced different finches.
The Galápagos Islands had finches that once shared a common ancestry. Darwin found that finches on one island had, over many generations, developed and adapted in differing ways to finches from other islands.
