I chose the reproductive system. How I wanted to show the evolution and the change was their eggs and where they lay them. Worms lay there eggs in the dirt. Frogs lay their eggs in water because its like a jelly casing so if they were to be laid on land they would dry out and the water keeps them moisturized. But alligators are totally opposite. They can not lay their eggs in water because the eggs would drown so they lay their eggs on land and the baby alligators have to find their way back to the water. But overall I learned a lot through the process of this benchmark and would't change anything about it!
