Oldest Homo Erectus Tools Found, Early Humans Had Tools Way Earlier Than Previously Thought

Oldest Homo Erectus Tools Ever Found

History.com - Early humans were creating and using advanced stone tools 1.8 million years ago, much earlier than previously thought, according to archaeologists who unearthed an illuminating new cache of artifacts in northwest Kenya. But Homo erectus didn't export the technology behind these sophisticated hand axes, picks and flakes when the species migrated out of Africa–if the traditional narrative is correct, that is, the researchers wrote in Nature this week.

Taller and more robust than modern humans but with a smaller cranial capacity, Homo erectus appeared roughly 2 million years ago and spread across Africa, Asia and parts of southern Europe before vanishing from the fossil record some 70,000 years ago. Thought to be our direct ancestors, these hominins probably mastered fire and were the first to develop cutting and butchering instruments known as Acheulian tools, named after an archaeological site in Saint-Acheul, France.

Made from chiseled stone, Acheulian tools improved upon the pebble-like chopping implements wielded by Homo erectus’ more primitive cousins such as Homo habilis. According to some scientists, the symmetry of Acheulian tools-epitomized by teardrop- and oval-shaped axes-suggests that Homo erectus might have used language to communicate, since the same regions of the brain control aesthetic awareness and speech. Others have pointed to the artifacts’ sophistication as evidence that their manufacturers could innovate, think ahead and understand spatial relations better than their ancestors.
