Hominids among themselves can be distinguished by the shape of the skull. So can human races and sexes. At the same time, you can not say that blacks have a different brain structure, even though they have what can be seen with the naked eye. Within a race, people also have different shapes of skulls, but this does not translate into large differences in the ratio of the size of the areas in relation to each other. Above that, the black race has much thicker bones, including the skull which further reduces brain volume. The article presents morphometric analysis and radiocarbon dating of human remains found in the Iwo Eleru cave in Nigeria, suggesting their similarity to African remains from the late Pleistocene. The discovery confirms the complex process of human evolution and the lack of knowledge about human evolution in West Africa.
