Anthropology is usually classified as a social science along with disciplines such as sociology, economics, political science and psychology but it has much in common with natural sciences like biology and geology as also with religion and art in the field of humanities. The diverse field of anthropology has broader scope than other social sciences. Anthropologists are interested in all human beings and their different aspects such as skin color, kinship system, religious beliefs, technologies and other aspects of life.
In physical anthropology, investigation of the evolution of the human species, physical variations among different human groups and anatomy of monkeys, apes and humans are studied. Primatology is a line of specialization within anthropology and it specializes in the evolution, anatomy, adaptation and social behavior of primates which constitutes the taxonomic order including humans.Anthropogists studying the variation in the human beings seek to measure and explain the similarities and differences among the people of the world.
