Question

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 humans
○ the observation of dog breeds

Explanation:

Darwin conducted experiments on pigeon breeding to test his hypothesis about the gradual appearance of new species through small changes in ancestral species. He studied artificial selection in pigeons to understand how traits could be modified over time, which related to his ideas on natural selection and speciation. The breeding of finches was more of an observational study of natural variation, not an experiment he conducted to test the hypothesis directly. Observing humans or dog breeds were not his key experiments for this hypothesis.

Answer:

B. the breeding of pigeons
