According to the naturalist and mathematician George Louis Leclerc (1707 1788), everything contributes to proving that the human race is not composed of species that are essentially different from each other; that on the contrary, there was essentially only one species of men, which, having multiplied and spread over the entire surface of the earth, underwent different changes. Some are climatic, others concern differences in food or ways of living; there are also epidemic diseases; and the infinitely varied mixture of more or less similar individuals; that these alterations were not so marked, and only produced individual varieties; that they then became varieties of the species, because they became more general, more sensitive and more constant through the constant action of these same causes.
Following Arthur de Cobineau's essay published in 1853 which aimed to establish a hierarchy between the different human races at the request of the United Nations Educational, Scientific and Cultural Organization (Unesco) who wanted to avoid the improper use of the term “race”, the anthropologist and ethnologist Claude Lévi-Strauss (1959-2009) in his work on race and history published in 1952, believed that there is no “human race” in the biological sense. By establishing a difference between the biological notion of race and the sociological notion of culture, he demonstrated, following George Louis Leclerc that the originality of peoples takes into account geographical, historical and sociological circumstances. But using the term race to designate geographic or cultural ethnic groups at that time still had a racist connotation that additional works has contributed to change.
By sequencing for the first time in the year 2000 a human genome or by adopting a method which allows reading of the genetic information preserved by its cell at the level of DNA or the support of genetic information which carries thousands of genes, Graig Venter, an American researcher specializing in molecular biology, put an end to the concept of “race” which lost all scientific basis because a genetic research established two undeniable facts: First, all humans are very close. Each of us would have the same collection of genes. However, some also have slightly diverse versions of certain genes. Secondly, all current human beings are literally Africans. Our species homo sapiens sapiens would have appeared in Africa we do not know precisely when? and where? But human anatomical traits of the current human being, would have emerged 300,000 years ago. We would have remained in Africa for 200,000 years, but beings were already moving to various places on the continent. These groups founded diverse and new populations which gradually colonized the entire planet. There are therefore no longer “races”, but a human species which has a unique origin which, depending on several circumstances of life, has undergone transformations which have had consequences on the quality of the skin of Men which have been misinterpreted in the point of having favored the development of segregationist, xenophobic and racial considerations having contributed to committing enormities throughout human history, notably the slave trade, colonization, shoah, and Apartheid, which aimed to exclude, exterminate and exploit individuals deemed to be of inferior category, but whose dignity has been restored by Scientifics researches.
