In this process Nature provides all of the varieties and Man selects the variations that are found most useful.

What is the biogeography?
The study of fossils or extinct organisms, which continues to provide new information and support current hypothesis about how evolution occurs.
What is paleontology?
These preserved remains of ancient organisms show the history of life on Earth.
What is the fossil record or what are fossils?
The ability of an organism to survive and produce more offspring than other members of the population.
What is fitness?
This is caused by random change in the gene pool and affects small populations more.
What is genetic drift?

What is uniformitarianism?
