All modern humans have navels because the slightly less modern humans we descended from had navels, and the not-quite human ancestors they evolved from (homo Habilis, perhaps) had navels, and our last common ancestor with chimps (7mya) had a navel, as did our last common ancestor with cows, dogs, whales (navels all) all the way back perhaps 300
