Australopithecus afarensis (Latin: "Southern ape from Afar") is an extinct hominin that lived between 3.9 and 2.9 million years ago in Africa. A. afarensis was slenderly built, like the younger Australopithecus africanus. A. afarensis is thought to be more closely related to the genus Homo (which includes the modern human species Homo sapiens), whether as a direct ancestor or a close relative.
A cell wall is a structural layer surrounding some types of cells, just outside the cell membrane.It can be tough, flexible, and sometimes rigid.
