I have always been fascinated by fossils, I could never understand the process that takes place that makes a bone, last for so long. especially when people dig up bones in their backyard, that aren't that deep, that are supposedly thousands of years old.
all things that exist on earth that are exposed to any amount of air light or water , id think, should decay.
so, we have such factual fossil records to prove these animals have changed.
we humans must be very new on the scene, since there are so few examples of humans evolving from something else.
I wont be around, but, women need to evolve to have eyes in the back of their heads,more strength , and an extra set of arms and hands.
and as for the polar bear, re-evolving to swim in the ocean, see, that's what I don't understand, things cannot now 'evolve' fast enough before they become extinct, to survive the rapid change of environment. a polar bear population will die off before they change to grow gills or have better coats, to live in water longer, since the ice is melting and their food source is changing. I doubt that people will evolve to survive the toxic planet that man has made. nor will animals. were due for a sixth mass extinction, then what?
