competition drives natural selection, as individual members of a species compete with each other for limited natural resources. The Canada goose and its subspecies may be undergoing , the process of new species forming or becoming distinct.
The of horses is comprehensive, and clearly shows the evolution of horses over millions of years.

Intraspecific

speciation

fossil record

The fossil record provides empirical evidence for evolution because it shows that species now aren't the same as species that existed in the past and that small changes happen over time to create new species.

A geographic variation in the fossil record occurs when two similar organisms occupy the same time span in two different places. These organisms hold the same purpose within the overall ecology.

A more detailed fossil record is preferable for supporting evolution because it allows for the instances of gradual change to be recorded and placed into broader speciation events.

Fossils provide a great many intermediaries that connect past species with their living descendants.

Intraspecific competition is competition that occurs within species. This is the competition that drives natural selection.
