Engineering:List of earliest tools

From HandWiki
Short description: none

The following table attempts to list the oldest-known Paleolithic and Paleo-Indian sites where hominin tools have been found. It includes sites where compelling evidence of hominin tool use has been found, even if no actual tools have been found.

Stone tools preserve more readily than tools of many other materials.[1][2] So the oldest tools that we can find in many areas are going to be stone tools. It could be that these tools were once accompanied by, or even preceded by, non-stone tools that we cannot find because they did not preserve.

Similarly, hard materials like bone or shell are more likely than softer materials to leave discernible cut marks on bone. Bamboo has been shown to leave cut marks on bone that are harder to see than cut marks by stone.[3] So the earliest evidence of tool use that we are likely to find are often cut marks made on bone by stone or shell tools. Therefore, it should not be assumed that the items on this list represent the earliest uses of tools in each area, but rather the earliest uses of tools that have been found.

Because it focuses on only the earliest evidence of tools, and since the earliest evidence is biased towards stone by stone's increased likelihood of preservation, this page necessarily omits mention of many significant ancient tools of non-stone materials simply because those cases are not among the earliest found within their geographic area. See Timeline of historic inventions for other noteworthy tools and other inventions.

With its focus on tools, this list also omits some sites with the earliest evidence for the existence of hominins, but without evidence for tools. Many such sites have hominin bones, teeth, or footprints, but unless they also include evidence for tools or tool use, they are omitted here.

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.

Geographic areas covered

For much of the 20th century, a "Clovis first" idea dominated American archeology. Many sites with dates too old to be compatible with "Clovis first" were published, but these were mostly dismissed under the hegemony of "Clovis first."[5][6] Meanwhile some indigenous archeologists insisted throughout the "Clovis first" era that the peopling of the Americas was much older than Clovis.[7] Recent publications with very strong evidence for pre-Clovis sites seem to have ended the hegemony of "Clovis first."[8][7][6][9]

Dikika[10] 3.39 Hadar, Ethiopia East Africa A. afarensis (presumed) Cut marks on bone Controversial[11][12][13]
Lomekwi 3[14] 3.3 West Turkana, Kenya East Africa Stone tools Mode 0 or Pre-Mode 1 stone tools are named after this site - see Stone tool
Nyayanga[15] 3.0–2.6 Nyayanga, Kenya East Africa Paranthropus (associated) Hominin remains, stone tools Some, e.g. Kathy Shick,[16] have suggested that the user of the tools may have been early Homo butchering Paranthropus as food.

Earliest known Oldowan tools[17]

Bouri Hatayae layer[23] 2.5 Ethiopia East Africa Cut marks and percussion marks on bone
Longgupo[24] 2.48[25] Longgupo, southwest China East Asia Stone tools and dental fragments Controversial. Russell L. Ciochon has retracted the attribution to Homo and casts doubt on the dates of the tools: "Although I no longer consider the Longgupo jaw to be human, the two stone tools still stand as described. They must have been more recent additions to the site."[26] Ciochon provides no direct evidence for his conclusion that the tools were "more recent additions."
