THE CIVILIZED HYBRID CRAFTSMEN Copper was the first metal to be used in making tools. After 4000 B.C., craftspeople in western Asia discovered that a combination of copper and tin created bronze, a metal far harder and more durable then copper. So at this era we see that copper and Tin; made Bronze...it interm phased out the uncivilized homo erectus and the Neanderthals white people Stone Tools Age . Take notice of the time in history.
THE UNCIVILIZED H. HERECTUS WHITE HUMANS TOOLS: Their tool kits included choppers, cleavers, and hammers as well as flakes used as knives and scrapers. It is quite likely that Homo erectus also made many implements out of more perishable materials such as wood, bark, and even grass, which can be easily twisted together to make string and rope.
Archaeologists working in two Italian caves have discovered some of the earliest known examples of ancient humans using an adhesive on their stone tools...Neanderthals made spear points with a stone or soft hammer. Traces of adhesive on some stone points suggest they were once attached to wooden shafts, perhaps glued with resin or tar and bound with plant fibers, sinew, or leather. Gays are of Erectus and Neanderthals! ( This is conclusive evidence White people are not the civilized develop category of Hybrid human being.)
