Ardipithecus ramidus dated nearly 4.4 million years ago, and it is located in Awash River Valley in Ethiopia. Key features of the Ardipithecus ramidus include the following;
Having the above characteristics, the Ardipithecus ramidus indicates that they were arboreal hominins that displayed bipedalism traits. Such trails suggest that humans might have had Ardipithecus ramidus as part of their ancestors (Larsen).
Some of the changes that occurred to the anatomical figures in bipedal hominin include the following
The hypothesis that explains a change to bipedalism is due to the changes in the forest covers. In turn, due to the patchiness of the forests, food became scarce and dispersed; meaning that they would use their arms to collecting the available food (Larsen).
