【Discussion】Do we humans evolve from fish?
|
|
In today's Archaeobotany class, we discussed the origin of the earth and our humans. As we all known, our planet has taken shape for 45 million years, and the life appeared 30 million years ago. The fish appeared 10 million years ago, have a long history than our humans ,fish was the only vertebrate in this period. So we have reasons to believe that fish is our ancestor.Our humans evolve from the fish. The strong evidence is that the our embryonic development identical with the fish.At the beginning both embryo have tail, but later our humans tail disapper due to the apoptosis.So we can make a conclusion that our humans have a great posibility come from the fish. what's your opinion? |
