I may be getting OT, but I started this thread so I get to bring up new stuff.
Does anyone know of the dicovery where fossils from a billion years were found. Now we are one "form" in so far as we have a Skeletal system AND a backbone AND symetry (2 arms, 2 legs, 1 on each side). I am no expert so I will say in my example there are 5 forms of animal still living, we mammals and 4 others (such as worms, with no backbone or skeleton etc). Anyway in the example I mentioned there were 20 "forms" of animal found. Thats the 5 current ones, and 15 "types" that are extinct. basically 1 billion years ago there were 20 possible templates for the creatures that would occupy the earth but 15 got covered with a landslide and only the other 5 survived (I am simplifying this alot, and my numbers might be wrong, but I am trying to point out something). So what if instead of the 5 that survived, 5 others survived. The earth might be populated by animals with no backbone and 3 legs and a head with an extendable mouth.
