Early Oldowan tools are also known from Gona in Ethiopia (near the Awash River), and are dated to about 2.6 Ma. [11] The use of tools by apes including chimpanzees [12] and orangutans [13] can be used to argue in favour of tool-use as an ancestral feature of the hominin family. [14]
Tools classified under this category are known as the earliest indicators of hand axe usage. The biggest difference from the early Oldowan tools, or choppers, is the fact that two sides have had flakes chipped off, versus the single side of the chopper.
The Lower Paleolithic (or Lower Palaeolithic) is the earliest subdivision of the Paleolithic or Old Stone Age.It spans the time from around 3.3 million years ago when the first evidence for stone tool production and use by hominins appears in the current archaeological record, [1] until around 300,000 years ago, spanning the Oldowan ("mode 1") and Acheulean ("mode 2") lithics industries.
A Mode 1, or Oldowan, stone tool from the western Sahara. The earliest documented stone tools have been found in eastern Africa, manufacturers unknown, at the 3.3 million-year-old site of Lomekwi 3 in Kenya. [8] Better known are the later tools belonging to an industry known as Oldowan, after the type site of Olduvai Gorge in Tanzania.
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]
At the nearby Gona site, where there is an abundance of raw materials, several Oldowan tools (an industry previously believed to have been invented by H. habilis) were recovered from 1992 to 1994. The tools date to around 2.6–2.5 mya, the oldest evidence of manufacturing at the time, and since A. garhi was the only species identified in the ...

In archaeology a chopper core is a suggested type of stone tool created by using a lithic core as a chopper following the removal of flakes from that core. They may be a very crude form of early handaxe although they are not bifacially-worked and there is debate as to whether chopper cores were ever used as tools or simply discarded after the desired flakes were removed.
