Document Summary
Spears found in sch ningen, germany; site was 400,000 years old, still from the lower paolothic stage, the spears were over 2 meters long, balanced well for throwing. These spears were found with a lot of horse remains, so they were obviously very successful at hunting horses. We can basically track the development of human technology through the creation and use of fire. Earliest evidence of controlled fire: south africa, swartkrams member (1. 0 1. 5 million years ago) Some animal bones had been heated to 400 degrees celsius or higher, hotter than most natural bush fires. To cook food, to be able to keep warm at night, fire provides life (the light from the fire extends the day, stay up longer, socialize for longer) Heated to 400 c, chert gains a smoother appearance. Made it easier to shape and craft figurines, such as the terracotta figurines, although. Compressive strength increases 25-40% while less force is required to flake it.
