Created with Fabric.js 1.4.5 Art Sculptures, cave paintings, rock paintings and petroglyphs from the Upper Paleolithic dating to roughly 40,000 years ago have been found, but the precise meaning of such art is often disputed because so little is known about the cultures that produced them. The oldest art objects in the worlda series of tiny, drilled snail shells about 75,000 years oldwere discovered in a South African cave.Containers that may have been used to hold paints have been found dating as far back as 100,000 years.

Science Science in a broad sense existed before the modern era, and in many historical civilizations, but modern science is so distinct in its approach and successful in its results that it now defines what science is in the strictest sense of the term. Much earlier than the modern era, another important turning point was the development of classical natural philosophy in the ancient Greek-speaking world. Technology The use of tools by early humans was partly a process of discovery and of evolution. Early humans evolved from a species of foraging hominids which were already bipedal, with a brain mass approximately one third of modern humans. Tool use remained relatively unchanged for most of early human history. Approximately 50,000 years ago, the use of tools and complex set of behaviors emerged, believed by many archaeologists to be connected to the emergence of fully modern language.
