In the 19th century archeologists discovered the remains of extinct , highly developed primates called Dryopithecinae , or tree apes . Charles Darwin , the great English naturalist , and his followers analysed the evolution of the animal world over the course of many centuries and used these discoveries to scientifically prove the biological relationship between man and the animal world , as well as man’s evolution from the highly developed fossil apes . The proof of this theory was to be found in the data provided by anatomy , embryology , paleontology and , specifically , by the basic similarity of skel etal structure , brain development and the composition of the blood of modern man and the anthropoid apes . The develop ment of modern science has proved the validity of this mate rialist theory magnificently .
Beginning with the 700th millennium B.C. , man began to fashion his first tools from stone . Later , he cracked and crushed stones to make his first crude stone implements with a cutting edge . Besides these primitive stone tools he also fashioned wooden tools such as sticks with sharpened tips , clubs , etc. From now on man consistently improved his tools to fit his purposes . He would sharpen both sides of a stone to make a chopper , a large universal tool with which he could chop , cut , strike an enemy and even dig . Such tools were made and used by a type of fossil man close in develop ment to the Pithecanthropus . At this stage , the invention of the chopper was man’s greatest achievement . The next stage in man’s evolution and in the development of the production of material values took place 500,000 to 300,000 years ago , when the first sharp oval choppers , chipped from all sides , came into use as did basically new tools especially fashioned for striking , cutting , digging , etc. In order to fashion the various scrapers , spears and other tools , man had to be skilled enough to strike the stone he was working on with great accuracy . This proves that in the process of production the human organism evolved and its co – ordination was perfected . π·The introduction of new tools brought about a change in primitive man’s entire way of life . With the aid of these new tools he could hunt such large animals as elephants , rhinoc eroses , buffalo , stags and horses . Now he could extract more food from the same area than formerly , and this made it pos sible for him to remain in a given area for a longer period of time . Primitive man began to set up temporary camps in places conducive to hunting : near lakes and rivers , along animal paths and the edges of forests , using caves for shelter .πΉ
