Introduction
When replaced within the evolutive process of species,
humans are primates, hominids sharing a close evolutionary
relationship with the great apes (gibbons, orangutans,
gorillas and chimpanzees). The chimpanzee (s) delete is our
closest living relative with whom we share a recent common
ancestor. This common ancestor is neither a chimp nor
a gorilla, nor a human. The study of fossil specimens and
comparative anatomy helped determine the time of split
between the main evolutive species. It is generally believed
that the chimpanzee-human split occurred about seven to
10 million years ago [1,2]. More or less preserved fossil
specimens were recovered and give us a clearer picture of
the human evolutionary line. The Australopithecus afarensis
currently name lucy, which lived between two and three
million years ago, was discovered within Eastern Africa and
is among the most famous and complete fossils ever found.

Despite partial similarities between lateral and medial
menisci in human beings, they display differences which
better highlight the specific lateral meniscus pathology. We
believed it was interesting to go back in time in order to
investigate the anatomic and pathophysiological specificity
of the lateral meniscus through the study of the comparative
anatomy and the embryologic development.
