WHAT DOES “EVOLUTION” MEAN?
... 1. There should be fewer and fewer species as we go back toward the beginning of life 3.5 billion years ago. 2. Earlier organisms should be simpler than modern ones. As organisms evolved they became more complex. 3. We should see evidence of life forms that are no longer found on Earth. 4. There sho ...
