Answer:
Speciation is the evolutionary process by which populations evolve to become distinct species
Step-by-step explanation:
There are four geographic modes of speciation in nature, based on the extent to which speciating populations are isolated from one another: allopatric, peripatric, parapatric, and sympatric. Speciation may also be induced artificially, through animal husbandry, agriculture, or laboratory experiments.[citation needed] Whether genetic drift is a minor or major contributor to speciation is the subject of much ongoing discussion.
