Well, the son of an australopithecus is an australopithecus, and the grandson of an australopithecus keeps being an australopithecus, and so on, but when some thousands or millions of years passing the fossils are not the same anymore, so you can say that that fossil you find is another species already. Correct me if I'm wrong.
