Anthropology and Earth Sciences

Anthropology and Earth Sciences have intimate relationship. The earth sciences include geology and human geography. Archaeology is closely linked to geology in analyzing the archaeological sites and in dating the past and finding out the chronological sequence. Anthropology, cutting across the barriers of time and space, naturally takes interest in men past especially prehistoric past. Thus archaeologists may be seen serving as the 'historians' among anthropologists involved in the cultural reconstruction of man's past. Till sometimes back the term prehistory or prehistoric archaeology has been popular. Unlike a socio-cultural anthropologist, an archaeological anthropologist cannot observe human behavior and culture directly but reconstructs them from material remains like pottery, tools, cave/rock paintings, ruins of shelter, ornaments and so many other material remains that survive the wear and tear of climatic factors. To recreate man's past without any written record is not an easy task. It is like a jigsaw puzzle. Interpretation of what went on in the past requires a lot of imagination and common sense.
To discover, analyze and interpret their finds archaeological anthropologists have to take the help of geologists, human geography and a host of other specialists. When one digs deep into the earth one cannot do without geology. When you date the past you require the help of human geography and others. But despite all this inter-disciplinary collaboration, the archaeological anthropologist shall always remain handicapped at least on one count. He will never be able to know as to what speech or language the prehistoric man was using. Still, reconstructing the past shall remain an anthropological preoccupation. Before launching a proper and planned investigation of the prehistoric anthropology of a selected area or region, it is quite important to study the past geography and climate besides geology. We have a fairly good account of the present day climate and geography of the world. But both these phenomena underwent drastic changes since the time when "man the tool-maker" first appeared in the beginning of Pleistocene epoch till to date the entire world over.
Hence a thorough knowledge of these changes is a matter of concern to pinpoint sites and settlements which formed the above of human groups, and their movements in search of animal and plant food. Such meaningful and objective assessment of the climatic conditions of the past mainly through geological deposits of different types and their impact on the life activities of prehistoric communities particularly with regard to their psycho-social development can be achieved with the assistance and association of a competent professional climatologist. Geology, the science of earth's crust, provides the law of stratigraphy which as the foundation of our knowledge of chronological order of facts with the position and nature of each stratum containing prehistoric remains furnishes information as to the relative antiquity of the finds as well as the strata. Further, the interpretation of the finds can be objectively done only when one explains the manner of the deposition of different layers. The archaeological strata formed by the effects of geological processes and mechanisms can help us in understanding the environment existed in the past.
As stone is the most imperishable material, it has been extensively used in the manufacturing of tools and weapons by prehistoric communities of different times. The knowledge of different rock types in relation to different prehistoric cultures is very essential in all prehistoric investigations. For all these things it is necessary to depend on the geologist apart from the prehistoric archaeologist who possesses a fairly good idea of these aspects. Pedology, the science of soils, is another potential field with which prehistory is related. The analysis of the soil is not only used in dating but also in understanding the manner of the formation of deposits as well as about the environment at the time of their formation. With the help of the pedologist it is possible to know whether the deposits were natural or man-made because it is these deposits, if at all artificial, which contain remains of ancient people.
