Anthropologists
Another type of scientist that studies human history are anthropologists. Anthropologists study humans and other human-like creatures known as hominids. They compare the bones, of these creatures to one another, looking for changes in brain size, and posture.
Mankind begin keeping a written history about 5,500 years ago. Much of what we think of as human history happened between then, and now. However, in reality this is just the scratch on the surface.
Anthropologists and archeologists have traced human history back some 4.4 million years.
