Question

Which theory was developed based on observations made on the Galápagos islands?

Answer 1

Answer:

Survival of the fittest, with the species that adapt the best to differnet conditions being the fittest

Explanation:

Darwin saw a lot of different finches on the galapogos islands. These finches looked a lot alike, but he noticed that they had subtle differneces based on which island they were living on. He saw that finches living on islands with lots of nut carrying plants had larger and heavier bills. He saw other finches with long, sharp bills on anohter island. These finches ate insects and nectar.

Darwin remarked one thing: there were little to no finches with long sharp beaks on the "nutty" island. There were also very few finches with the heavy beak on the island with plants and insects. The finches that weren't native to the island could not eat enough to survive. He noticed that only the finches that were the fittest to the island survived, hence, the survival of the fittest.
