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 pigeon - breeding experiments to study how small changes could accumulate over time. He observed the variety created through artificial selection in pigeons as an analogy for natural selection and the gradual appearance of new species. The breeding of finches is more associated with his observations on the Galapagos Islands but not as a direct experimental test of this hypothesis as pigeon - breeding was. Observations of humans and dog breeds were not his main experimental tests for this hypothesis.

Answer:

the breeding of pigeons
