Homo SapiensHomo sapiens is the species that all modern humans belong. Homo sapiens is one of the grouped Homo species in a class and the only one from the Homo species that has not disappeared. The meaning of Homo sapiens comes from Latin and stands for the 'wise man'. The name of Homo sapiens was first used in 1758 by Carolus Linnaeus. It was then known for a long time that people are much more physically similar to primates than any other known living organisms. This resemblance, that the human being is so similar to the primates was then an act of great daring. Linnaeus was only concerned by the similarities in body structure with the primates, and faced the problem of distinguishing Homo sapiens from apes such as gorillas, chimpanzees, orangutans and gibbons, which differ from humans in numerous tangible and cognitive features. The evolution of Homo sapiens in this perspective is much more detailed in the theory on the evolution of Charles Darwin called the Origin of Species that will occur 101 years later.
From Linnaues’s theory there were discovered many fossils along history. This archive contains numerous missing species that are more alike to man than primates in present and they seem more like us in terms of behavior. Following the footsteps of our ancestors from the distant past raises the question: what is the meaning of the word human? The definition of Homo sapiens is human whereas primates do not mean the same thing. In terms of behavior, only Homo sapiens can be said to describe and define the 'fully human', but even the definition of Homo sapiens is sometimes a matter for debate as many pale anthropologists include in human evolution our Homo species and primate species also. The term of Homo sapiens with its complete meaning is very recent that probably appeared less than 150 000 years ago.
