Now, it doesn't reach the same kind of headlines because there's many different infections and different parts of the body and different bacteria. Their feet are webbed and this trait makes them fast swimmers. They were therefore able to eat aquatic plants and get enough food to survive and reproduce.Ducks with more webbing were better at eating aquatic plants than ducks with less webbing, so the ducks with more webbing survived and reproduced better than ducks with less webbing.Ducks with less webbing needed to grow more webbing in their feet in order to improve their access to aquatic plants, which allowed them to survive better and reproduce more.Q6.10.
