Darwin's Finches

Darwin's finches are a group of small black birds that inhabit the Galapagos Islands. They played a significant role in Charles Darwin's theory of evolution by natural selection.

Discovery of Darwin's Finches

Darwin first encountered the finches during his voyage on the HMS Beagle. He noticed that the birds on different islands had different beak shapes and sizes. He hypothesized that the variations were adaptations to the different food sources available on each island.

Types of Darwin's Finches

There are 13 species of Darwin's finches, all of which are endemic to the Galapagos Islands. Each species has a unique beak shape and size that is adapted to a specific type of food.

Importance of Darwin's Finches

Darwin's finches provided crucial evidence for the theory of evolution by natural selection. The variations in beak size and shape among the finches demonstrated that species can evolve over time in response to environmental pressures.

Conclusion

In conclusion, Darwin's finches are a group of small black birds that played a significant role in the development of the theory of evolution by natural selection. Their unique beak shapes and sizes demonstrated how species can adapt to their environment over time.

The correct answer is option 4
Darwin's finches are small land birds.They're brown and black birds which live on these lava rocks on the Galapagos Islands. What is remarkable about these birds is that there's about fifteen species, each of them is eating a different type of food.
