Evolutionary biology is the subfield of biology that studies the evolutionary processes that produced the diversity of life on Earth, starting from a single common ancestor.These processes include natural selection, common descent, and speciation. The discipline emerged through what Julian Huxley called the modern synthesis (of the 1930s) of understanding from several previously unrelated.
