There is, broad agreement in the scientific world today that all humans share common origins in Africa, but when Charles Darwin first suggested it in 1871, few European scientists took his theory seriously. When the Taung child skull was found in South Africa in 1924, Raymond Dart supported Darwin's theory, but it did little to shift scientific opinion. In the 1980s, when genetics research concluded that all living humans can trace their maternal ancestry back to Africa 200 000 years ago, many international scientists were slow to accept this claim.
