How can we tell apart million or more year old skeletons of human ancestors and chimp bonobo ancestors skeletons from a similar time period?

Telling apart the skeletons of human ancestors and chimp bonobo ancestors from a similar time period can be challenging. However, there are several key differences that can help us distinguish between the two.

  1. Pelvis: The pelvis of human ancestors is wider and more bowl-shaped than that of chimp bonobo ancestors. This is because human ancestors walked upright, which required a wider pelvis to support the weight of the body.
  2. Femur: The femur, or thigh bone, of human ancestors is longer and straighter than that of chimp bonobo ancestors. This is because human ancestors walked upright, which required a longer and straighter femur to support the weight of the body.
  3. Teeth: The teeth of human ancestors are smaller and have a more complex structure than those of chimp bonobo ancestors. This is because human ancestors had a more varied diet than chimp bonobo ancestors, which required a more complex set of teeth to grind and process food.

By considering these key differences, we can tell apart the skeletons of human ancestors and chimp bonobo ancestors from a similar time period.
