I gotta say, I'm both stoked & a little skeptical about this whole Sahelanthropus thing 
7 million years ago is like, ancient history! I mean, can we really pinpoint what our human ancestors were up to back then? The femoral tubercle and all that jazz sounds legit, but at the same time, I'm thinking... maybe it's just some apes trying to blend in with their two-legged cousins 
. And then there are these other factors like tree walking vs ground walking... it's like trying to figure out who ate the last donut in the break room 
- nobody knows for sure! But hey, keeping me on my toes is what fossil hunting is all about
