The Adam and Eve picture from the "Truth Shall make you Free" shows how the Witchtower has no real sense of timescale.
Adam has no beard because Eve was created so sooon after him, it had not had the chance to grow. Was he created as a 15 yr old boy at his sexual peak, but like most males at that age a sparse growth??
As for the little cute snake with legs and its wee hands clasped with glee:
Snakes did originally have legs. Some varieties still have pronounced hips and shoulderblades, as well as vestigial toes with a claw.
But they got that way millions of years before the Eden fairy tale.
