Question

an explanation of earths diversity
take a moment to reflect on what youve learned so far.
charles darwin, who journeyed to the galapagos in 1875, made an observation that tied together the different observations you made in this lesson. when observing the finches on these islands, darwin hypothesized that the finches all came from one ancestral bird. the population of this bird had a variety of different traits as a result of descent with modification (offspring having various mutations - or traits - not found in their parents). normally, this would just create a random chaotic mess of different traits. as this population of birds spread out over the islands, each landed in a different environment. these different environments exhibited a force of natural selection on the finches, causing specific traits to be favored. through this process, random mutations were guided into specialized traits to suit a particular environment.
