Fossil analysis showed an unusual foot in the big toe, not straightened but extended outward as is often seen in chimpanzees and gorillas.

The direction of the toe allows the feet to easily grip the branches, indicating the ancestors of modern people climbing and 'making houses' on the canopy.

'This is an important finding because it helps us to understand the evolution of human ancestors' feet - Professor of Anthropology Bruce Latimer (Case Western Reserve University, Ohio, USA), author of the study. save, say.

'This fossil bone fossil shows that human ancestors are much more complex than the researchers once thought when A. afarensis completely walked on both feet and did not live on trees' - co-author save, Yohannes Haile-Selassie (Cleveland Natural History Museum, Ohio), said.
