”Out of Africa Theory”

The Out of Africa Theory is a widely renown theory describing the origin of the human race and their early dispersal throughout the world. According to this theory, humans have a monogensis, or a single and common origin; Africa. The concept was first introduced in 1871 by Charles Darwin but was deliberated for years until further studies of mitochondrial DNA and evidence ”based on physical anthropology of archaic specimens” was added. During the early 19th century, scientists, archeologist and other scholars, speculated, studied and disagreed about the development of humans and our origins. Some experts theorized that humans are monogenism and developed into various varieties of species. Others argue that we are a polygenism mammal and that we either had separate development of various human species or developed as separate species through ”transmutation” of apes. It was until the year 1871 when one of the first theories had been proposed openly. During that year, Charles Darwin published the book ”Descent of Man”, in which he suggested that all humans were descendant from early humans who lived in Africa based on his studies of the behavior of African apes. In his book, Charles Darwin concluded, ”In each great region of the world the living mammals are closely related to the extinct species of the same region. It is, therefore, probable that Africa was formerly inhabited by extinct apes closely allied to the gorilla and chimpanzee; and as these two species are now man's nearest allies, it is somewhat more probable that our early progenitors lived on the African continent than elsewhere. But it is useless to speculate on this subject, for an ape nearly as large as a man, namely the Drypithecus of Lartet, which was closely allied to the anthropomorphous Hylobates, existed in Europe during the Upper Miocene period; and since so remote a period the earth has certainly undergone many great revolutions, and there has been ample time for...
