PZ: "We were always told that eventually Adam and Eve would be allowed to eat of the tree of life.
A&E were invited to eat of all the vegetation, including the prominently centered tree of life right from the beginning, with the exception of the tree of knowledge. there were not two forbidden trees, nor a hidden tree. perhaps A&E were later, after a period of abstinence (good obedient doggies) allowed to eat from the knowledge fruit. Clearly the animals ate of that wisdom tree, scientist study them all the time, to copy the amazing bionic capabilities. May be that is how the snake got to be able towalk and talk?
