What hypothesis did Darwin investigate by studying the breeding of pigeons with distinctive traits?

New species can appear gradually through small changes in an ancestral species.

The amount of variation in a population is related to the type of environment it lives in.

Organisms have only the number of offspring that are supported by the environment.

Some traits appear in each generation, while others seem to disappear in some generations.

Peter · Answer 1

New species can appear gradually through small changes in an ancestral species.

Explanation:

The new species that appear are due to hereditary variations that occur in a population. The adaptive variations are said to confer a selective advantage to organisms possessing them. The result of variations is that well adapted individuals are able to survive and reach the reproductive age and pass over their favourable characteristics to their offspring.
