Natural selection and Artificial selection

Natural selection- the process by which organisms with favorable variations reproduce at higher rates than those without such variations. ex.-Galapagos tortoises and finches

Artificial selection- breeding of organisms by humans for specific phenotypic characteristics
ex.- Dogs are bred for different kinds of dogs.

Natural selection is a part of nature while artificial selection involves humans interfering with the breed type.
