Are you suggesting that humans existed 90 million years ago? (Remember, the snake's curse is related to the fall of man.)
It doesn't make a whole lot of sense that God would curse an entire species because Satan assumed the form of one member of the said species either. Seems unjust by today's standards. Maybe it made more sense to those who believed in punishing future generations of unlawful folks.
To me, it the article seems entirely unrelated to the GOE story.
