The oldest known Oldowan tools have been found at Nyayanga on the Homa Peninsula in Kenya and are dated to ~2.9 million years ago (Ma). [10] The Oldowan tools were associated with Paranthropus teeth and two butchered hippo skeletons. [10] Early Oldowan tools are also known from Gona in Ethiopia (near the Awash River), and are dated to about 2.6 ...
This list excludes tools and tool use attributed to non-hominin species. See Tool use by non-humans . Since there are far too many hominin tool sites to list on a single page, this page attempts to list the 6 or fewer top candidates for oldest tool site within each significant geographic area.
Oldowan tools infrequently exhibit retouching and were probably discarded immediately after use most of the time. [57] The Oldowan was first reported in 1934, but it was not until the 1960s that it become widely accepted as the earliest culture, dating to 1.8 mya, and as having been manufactured by H. habilis.
Archaeologists in Kenya have dug up some of the oldest stone tools ever found, but who used them is a mystery. In the past, scientists assumed that our direct ancestors were the only toolmakers.
The brains of the hominins who used Oldowan stone tools were a lot smaller than the brains of modern humans. [9] There is debate about the Oldowan Industry's place in human culture's evolution. [9] [30] This debate features some of Gona's Oldowan assemblages as evidence and pulls from research on primate social behavior. [23] [9] [31] [32] [33]
Oldowan tools occur in Beds I–IV at Olduvai Gorge. Bed I, dated 1.85 to 1.7 mya, contains Oldowan tools and fossils of Paranthropus boisei and Homo habilis, as does Bed II, 1.7 to 1.2 mya. H. habilis gave way to Homo erectus at about 1.6 mya, but P. boisei persisted. Oldowan tools continue to Bed IV at 800,000 to 600,000 before present . A ...
Because OH 5 was associated with the tools and processed animal bones, they presumed it was the toolmaker. Attribution of the tools was promptly switched to the bigger-brained H. habilis upon its description in 1964. [3] In 2013, OH 80 was found associated with a mass of Oldowan stone tools and animal bones bearing evidence of butchery.
The appearance of early hominins in Eurasia coincided with a reduction in the diversity of the continent's carnivore guild. It has been postulated that this was related to the Oldowan-Acheulean transition, as the development of Acheulean technology signifies a change in human ecology from a passive, scavenging role to that of more active predation.
