BIOLOGICAL ANTHROPOLOGY- A NEW CONCEPT


BIOLOGICAL ANTHROPOLOGY- A NEW CONCEPT
            During recent period the impact of genetical theory into the domain of physical anthropology has brought forth a revolutionary change in the line of thinking. In addition to measurements, observations and necessary analysis of human bones and different bodily parts, the modern physical anthropology has entered into the categorical study of various physiological perspectives through biochemical and genetical viewpoints and less stress has now been given on the linear measurements. The new physical anthropology is not interested in restricting itself in the study of the superficial bodily parts, rather through the adaption of new methodology it pledges to explore the mysteries of various internal features of human biology. In order to study human diversities the new physical anthropology relies extensively on population genetics which offers the physical anthropologists a clearly formulated and experimentally verified conceptual theme. The human races are now best considered as Mendelian populations which are centered round a purely genetic concept. Because of this integrated biology-oriented approach of the present day physical anthropology it is thought desirable to call it Biological anthropology.
            By virtue of its new concept the scope of biological anthropology has very naturally been expanded and integrated. It promises to study human evolution and differentiation in the background of biological variations in primates. While studying the nature and extent of fossil men and living men attempts are made to explain the various process and products of evolution such as anatomy, serology and behavior in respects of natural selection in association with genetics and environmental effects and cultural adaptation. It also pledges to reconstruct the past events of human being and to analyse and project current trends.
            The criteria for racial discrimination, that we are still using, are nothing but superficial characters. In recent time the attention of the physical anthropologists have been diverted and they look at the less obvious but intrinsically more important differences such as blood types, differences in musculature, etc. also they have started to study the group differences in time of sexual maturation, in growth rates and various disease immunities. Naturally, these factors are more reliable because of the facts that these3 are based on genotypical features. Also these have got some practical importance and the results may be used in various ways. On the other hand, the factors like head length, nose form, etc., on considering all these it may be concluded that the outlook of the physical anthropologists of today have been changed to a remarkable extent.
