Ardipithecus Ramidus: Evidence for Evolution or Extinct Ape? (Classroom Series)

Artie is significant because we believe she walked upright based on where her spine enters her skull.

Was the skull complete like shown in the Science Journal? Actually no. They reconstructed it from over 110 bone fragments found over a 30 -foot area.

Right. So how did her spine enter her skull from the pieces they found? I mean there's not much to go on there.

Did they find any neck vertebrae? Well actually again no. We have no neck vertebrae.

So let me get this straight. So they have no base of the skull, they guessed on where the spine entered the skull, and they have no neck vertebrae?
