This website link provides an article that shows the evolution process of an elephant. Elephants have evolved from Proboscideans. They probably evolved due to enviromental changes and lack of food. A large number of the species probably died off in order for the other elephants to survive and flourish. This is my response.
This video describes what evolution is and the process of it. This is my response.
This picture shows the evolution process for a whale. They started out as land animals. But they were almost extinct due to lack of food. Some whales went into the water and they reproduce until they were common in the ocean. The whale evolution is an exact example of natural selection because one part of whales died to let the entire whale population survive and fluoish. This is my response.
