Darwin hypothesized that new species could appear gradually through small changes in an ancestral species. what experiment did he conduct to test this hypothesis? the breeding of finches the breeding of pigeons the observation of plants the observation of dog breeds

The correct answer is - the breeding of finches.

Charles Darwin has hypothesized that a new species can appear gradually, after a longer period of time, through small changes in an ancestral species, and in order to prove his hypothesis Darwin conducted an experiment with the breeding of the finches. The finches that Darwin took as an example, and was conducting his experiment on, were finches from the Galapagos Islands, west of the coast of South America. He was conducting the experiment on these finches because they were different from the ones on the mainland, mainly in the shape of their beaks, and what were they feeding on.

Darwin concluded that after the ancestral finches reached the island, they started to gradually change their beaks, and partially their appearance, because of the food they had at disposal, so they had to gradually change in order to be able to survive. Also, because of the competition, and the limited food source, they started to diversify and take different niches in the food chain.

the correct answer is the breeding of pigeons.

explanation:

the fossil record extends back to a dog-like ancestor some 55 million years ago, which gave rise to the first horse-like species 55 to 42 million years ago in the genus eohippus.
