Dogs!

Man's best friend since our dumb asses fell out of the trees and couldn't climb back up, alerting us to danger and aiding us in our hunts. Nowadays, It's not uncommon to come across a working dog exploring the world that is making a bigger paycheck than you. The evolution of the dog has progressed so rapidly that it knows more about how to survive an encounter with alien invaders than most people do. There is even one account of a dog disarming a nuke somewhere up north. Man, that's one good-ass dog.
