Which animals were first to be domesticated? Why?
Dogs are believed to be the first animals domesticated, and there are two main theories why. The first
theory is that dogs may have evolved from a canid ancestor similar to the pariah dogs that populate many
underdeveloped countries today. The second theory is that dogs are domesticated wolves. In this theory, wolf
pups were hand-raised by humans.
