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?
o the breeding of finches
o the breeding of pigeons
o the observation of humans
o the observation of dog breeds

Explanation:

Darwin conducted experiments on pigeon breeding. By selectively breeding pigeons, he could observe how small, gradual changes could lead to new varieties. This was a practical way to test the idea that new species (or in this case, distinct pigeon varieties) could arise through cumulative small changes in an ancestral form. The finch observation was more about natural selection in the wild (on the Galapagos Islands) rather than a controlled experiment by Darwin himself. Observing humans or dog breeds was not the key experiment he did to test the hypothesis of new forms arising through gradual small changes in an ancestral species in a more controlled - like breeding experiment.

Answer:

the breeding of pigeons
