Humans learn to kill with sharpened pols.

The earliest example of sharpened wooden pole, or spear, comes from schoningen in Germany. There eight spears were dated to 400,000 B.C.E. The ancient hominid hunters who sharpened each pole use a flint shaver to cut away the tip to form a point & then singed the tip in the fire to harden the wood, making it a more effective weapon. A similar technique was used by hunters in Lehringen near Bremen in Germany, where a complete spear was found embedded inside a mammoth, skeleton, suggesting such spears were used mainly for hunting rather than warfare or self- defense. The need for food was so great that a mammoth would be attacked with only flimsy spears, although its use would have been more to scare the mammoth in the direction of a trap or pit dug previously than to attack it directly.

Around 60,000 B.C.E, Neanderthals living in rock shelters & temporary hunting camps in France sharpened small pieces of flint & slotted them into the tips of their spears. Hunters in the Sahara used sharpened stones in the same way, while Central Americans used obsidian, a natural volcanic glass. Around the world, Stone Age people gradually learned how to work small stones or flints into tiny, sharpened blades known as microliths for use as spear points. The greatest advance however came with the development of metalworking, notably cooper, in an alloy of copper & tin, around 2300 B.C.E, and then iron a millennium later. The new technologies effective spear points.

Clothing (c. 400,000 B.C.E.)

Early human cover their nakedness.

Around 400,000 years ago, Homo sapiens devised a solution to protect the vulnerable naked human body from the environment – clothes. Anthropologists believe the earliest clothing was made from the fur of hunted animals or leaves creatively wrapped around the body to keep out the cold, wind & rain.Determining the date of this of this invention is difficult, although sewing needles made from animal bone dating from about 30,000 B.C.E have been found by archeologists however genetic analysis of human body lice reveals that they evolved at the same time as clothing. Scientists originally thought the lice evolved 107,000 years ago, but further investigations placed their evolution a few hundred thousand years earlier.

Clothing’s has changed dramatically over the centuries, although its ancient role as an outward indication of the status, wealth & beliefs of the wearer is an important as ever; During the industrial revolution the textile industry was the first to be mechanized, enabling increasingly elaborate deigns to be made at a faster rate. In the twenty –first century. Mechanization has allowed sophisticated practical clothing to be devised to protect us from dangers such as extreme weather, chemicals, insects, & outer space without clothes we would not have been able to explore & exploit our world & the surrounding universe to the extent that we have.
