Hurum didn't say this provided evidence of human-ape evolution.
Hurum said that this was exciting because it would be a common ancestor to humans.
According to common descent we are all descendants of the first amphibians to become reptiles; so finding a transition would be exciting because it would be an ancestor to all terrestrial mammals.
But nobody said Tiktaalik shed any particularly keen insight onto the reptile to mammal transition (or “proved” it); because it didn't.
Similarly, nobody reputable said Ida shed any particularly keen insight onto the monkey to ape transition or the ape to human transition (or “proved” it); because it didn't.
It is incapable of even addressing an issue (let alone proving it) which would not take place until some millions of years later. Capiche?
“Hurum said that this was exciting because it would be a common ancestor to humans.”
And presumably he views apes as a common ancestor of humans?
Hurum also didn't say he thought humans evolved from lower forms so I guess that means something, maybe not though.
But this is completely irrelevant since this wasn't the point of the article posted but rather all the hype laid on Ida:
“It is incapable of even addressing an issue (let alone proving it) which would not take place until some millions of years later. Capiche?”
"Capiche"? I once owned a Chevy Capiche, pretty good car for while.
