What were the requirements for tattoos between different tribes in Paleolithic Age?

For example, aborigines in Australia, people of the same race tattoo the same patterns and characters on their bodies to distinguish them from other races. Mosayan people living in the Pacific Islands must get tattoos when they reach the age of 16 to symbolize adulthood. Eskimos in cold regions, when men reach the age of 8, begin to prick their faces, chests, arms and thighs. Tattooing is more common among American Indians. In the south of China, there is also the custom of "depicting his body with patterns and absorbing it".
