Eventually, one (or several) of those grass plants evolved, by accident, a gene sequence that allowed it to continue to grow (dare I say heal) even after having the larger share of itself devoured. This accident allowed that plant to live, and thereby reproduce at a greater rate of overall success. No magic, just random events that happened over a section of time. > -----Original Message----- > From: HP-3000 Systems Discussion [mailto:[log in to unmask]] On Behalf Of Wirt > Atmar > Sent: Tuesday, September 02, 2008 9:44 AM > To: [log in to unmask] > Subject: Re: OT: McCain Running Mate > > I just wrote: > > > The most primitive of the snakes, the boas, still retain vestigal hindlimbs, > > and in the most progressive of the skinks, which are not yet fully legless, > > are now found in the process of losing their forelimbs: > > > > http://en.wikipedia.org/wiki/Neoseps > > Let me add that I just found a much better picture of the Sand Skink, a lizard > in transition of adopting a snake-like ecology.
