Morphological or molecular evidence shows evidence for evolution for chimpanzees because they descend from humans.
Humans- Both structures have hair and not fur, almost identical internal anatomies such as the circulatory, digestive, and respiratory system. Both can walk like humans and have eyes, ears, and mouth, as well as opposable thumbs.
Bonobos- Both species can walk upright
This is a resemblance between a chimpanzee and a bonobo, humans can also stand upright, which makes all three organisms alike. http://www.collective-evolution.com/2016/02/13/are-we-more-like-chimps-or-bonobos/
A homologous structure is an example of an organ or bone that appears in different animals. This shows evidence for evolution for chimpanzees because humans evolved to do the same thing.
This is a picture of a human skeleton, showing that there are many bones in the human body that appear in several different organisms.
This is an example of the human anatomy of the organs and intestines, that appear in several other structures and living things.
Caecum- Very large and contains bacteria. Chimps eat a high proportion of leaves which are hard to digest. The caecum is not needed because the apes have a functioning appendix, unlike humans.
A vestigial structure is an organism that has lost all or most of its original function in the course of evolution. Vestigial structures show evidence for evolution because they are often homologous to structures that are functioning normally in other species.
This is a caecum, a no longer functioning organ in the body of a chimpanzee.
- Humans- They share the same type of DNA and both walk the same and are intelligent and able to understand things and learn.
- Australopithecus- Both have small brains
Transitional fossils are remains of a life form that inhabited traits through it´s ancestors. They show evidence for evolution because they show changes in traits of species over time that were caused by change in living conditions.
