Body composition in Pan paniscus compared with Homo sapiens has implications for changes during human evolution.

摘要: The human body has been shaped by natural selection during the past 4–5 million years. Fossils preserve bones and teeth but lack muscle, skin, fat, organs. To understand evolution of form, information about both soft hard tissues our ancestors is needed. Our closest living relatives genus Pan provide best comparative model to those ancestors. Here, we present data on composition 13 bonobos (Pan paniscus) measured anatomical dissections compare with Homo sapiens. These suggest that females males (i) increased (ii) decreased relative muscle mass, (iii) redistributed mass lower limbs, (iv) skin evolution. Comparison between provides new insights into function composition.
