Evolution is defined in biology, the idea that species change over time and have a common ancestor. (Park, 2014, p. 407) There are many theories of evolution in different and many different philosophers on which evolution is the most correct. Natural selection by Charles Darwin which would probably be the most common known theory and what a lot of people would think of when they are asked what is evolution. “One general law, leading to the advancement of all organic beings, namely, multiply, vary, let the strongest live and the weakest die.” Charles Darwin. There are multiple subfields of anthropology to help us understand the evolution of humans and different species around the world.
Biological anthropology also known as physical anthropology, study the non-cultural aspects of human and non-humans, which are monkeys and apes. ("What is Anthropology: Fields of Anthropology," n.d.). Physical Anthropologists study this by looking at things that are not learned from living, but studying what humans and non-humans have inherited

The first major evolutionary change in the human diet was the incorporation of meat and marrow from large animals, which occurred by at least 2.6 million years ago (Pobiner, 2013). The diet of early humans was probably closely related to the diets of modern chimpanzees, which was fruits, flowers, bark, insects and meat (Pobiner, 2013). Anthropologists would have studied the fossils of these humans and study their teeth to be able to determine what kind of diet early humans would have had. Another way the anthropologists use fossil evidence to determine our diet were marks found on bones from where early humans used tools that would leave marks on the bones, cutting meat off a bone can leave cut marks. Pounding a bone with a large stone to break it can open and extract the marrow inside can leave percussion marks (Pobiner,
