He discovered that each finch in each diffrent island had a slightly diffrent beak adapted to its particular environment. For example, a fruit eater had a stout beak to pick berries off branches and a seed eater had a short, powerful bill for crushing seeds, etc. This contributed to his theory of evolution.
He noticed that the finches all had different beaks which varied in sizes. He concluded that this could be due to them living on different islands where the food sources were different so the would have had to adapt themselves to suit their living environment.
The Finches all had different beaks to help them adapt to their environment and survive.
that they had distinct beaks to fit their life style
he found it
Darwin was interested in the finches! The finches weren't interested in him!
On each island of the Galapagos Islands
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
The embryos help Darwin find that finches came from the same ancestor which they go through phases of evolutions, this depends on the island the finches are located. Darwin discover that in different islands the beak from the finches were bigger hence stronger to crack difficult shells from plans, but in a different island finches have smaller beaks to get nectar from that plants. Darwin came to the conclusion that finches adapt from their environment.
Darwin was puzzled about the many adaptations of the finches on the Galapagos Islands
Finches and turtles
Finches...he based his theory on the shape of their beaks
That they were evoled from on specie of finches.
