Artificial Selection is when humans breed animals and plants so that they develop desired traits. It has been used in agriculture for thousands of years as in how teosite was bred to grow larger exposed kernels to become maize. The dog above is a mixture of a greyhound and a chocolate lab (Canis lupus familiaris) and it was bred to be athletic like a greyhound, but also to be loving and a great companion like a lab.
