MadSci Network: Evolution |
If the conditions were right for life to start on this planet millions of years ago, why are they not right for life to start today? Why can't we find a naturally occurry chemical soup where life is just ready to start? If evolution could create bacteria, fish, dinosaurs, mammals and humans once, why could it not duplicate the process again and again? I have read that scientists believe that life must have evolved and then been wiped out several times when the earth was being formed. How is it that only one start of life was successful? Is it possible that not all creatures go back to the same begining?
