Finches...he based his theory on the shape of their beaks

finches
the animal Darwin examined were finches on the Galapagos islands (at least finches were the main thing he studied)
he studied the differences in finches of the three galapagos islands.
On each island of the Galapagos Islands
The Galapagos Islands.
The type of speciation that occurred among the Galapagos Islands finches is called "allopatric" speciation. Allopatric comes from roots meaning "other country". The immigrant finches, and many other birds and animals, were very isolated from other populations of the same species on the individual Galapagos Islands. The finches developed into at least 13 different species of finch on the islands.
The Galapagos finches only exist on the islands and inspired Charles Darwin. They implied that evolution occurs through natural selection.
Charles Darwin reached the Galapagos islands in 1835. He observed many finches, tortoises and many other animals. He observed that the animals in the Galapagos were different than the animals in other places like south America. This may be because the climate is different in the Galapagos than in other places so the animals may have involved to suit the temperatures in the Galapagos.
No, evolution has created different species of finches on the Galapagos Islands. There are 15 different species that are found on the Galapagos islands.
Charles Darwin thought that the original population of finches were blown over from South America to the Galapagos Islands.
