I think reporters should lay off on this stuff too. I mean the real point of that article must be to support evolution or cause controversy, because if it was concrete truth, who the heck would care about this so-called finding?
Anyway, maybe this is the real reason snakes are bad

"And the LORD God said unto the woman, What is this that thou hast done? And the woman said, The serpent beguiled me, and I did eat.
And the LORD God said unto the serpent, Because thou hast done this, thou art cursed above all cattle, and above every beast of the field; upon thy belly shalt thou go, and dust shalt thou eat all the days of thy life:
And I will put enmity between thee and the woman, and between thy seed and her seed; it shall bruise thy head, and thou shalt bruise his heel."
