See if you can find anything on the next latest direct ancestor of man. Or the next before that.

You keep saying things that demonstrate your cluelessness about the theory you think you're debunking.

As with most things related to evolution, we are talking about a slow and gradual process. There is not a binary distinction, going back in time, where we say, "This species ends precisely here, and this one begins here.

I forget where this thought experiment comes from, but think about your mother holding hands with her mother, who's holding hands with her mother, etc., back for, say, 6 million years. While it will be clear that the women on either end of the chain belong to different species, there's not a single place along the chain where you could say, "a-ha! here's a mother of species x who gave birth to a daughter of species y!" It doesn't work that way, and this is perfectly in line with the theory. So your request to come up with the precise 2 species that preceded our own is nonsensical.

Having said all that, maybe the simplistic answer you're looking for is H.erectus and H.habilis. The wikipedia page on Human Evolution is pretty good. Have a look.
