How many species of finches are there in the Galapagos?

Adaptive Radiation: Darwin's Finches. There are now at least 13 species of finches on the Galapagos Islands, each filling a different niche on different islands. All of them evolved from one ancestral species, which colonized the islands only a few million years ago.

Also question is, what are the 13 species of finches?

The finches found in Galapagos are:

  • Green warbler finch (Certhidea olivacea).
  • Grey warbler finch (Certhidea fusca).
  • Mangrove finch (Geospiza heliobates).
  • Woodpecker finch (Geospiza pallida).
  • Large tree finch (Geospiza psittacula).
  • Medium tree finch (Geospiza pauper).
  • Small tree finch (Geospiza parvula).

Similarly, why did Darwin's finches have different beaks? Darwin wondered about the changes in shape of bird beaks from island to island. So-called cactus finches boast longer, more pointed beaks than their relatives the ground finches. Beaks of warbler finches are thinner and more pointed than both. These adaptations make them more fit to survive on available food.

Also asked, how do we know the finches are different species?

Darwin's finches are a classical example of an adaptive radiation. Their common ancestor arrived on the Galapagos about two million years ago. During the time that has passed the Darwin's finches have evolved into 15 recognized species differing in body size, beak shape, song and feeding behaviour.

What did Charles Darwin discover about the finches?

On his visit to the Galapagos Islands, Charles Darwin discovered several species of finches that varied from island to island, which helped him to develop his theory of natural selection.
