Timeline of historic inventions

The dates listed in this section refer to the earliest evidence of an invention found and dated by archaeologists (or in a few cases, suggested by indirect evidence). Dates are often approximate and change as more research is done, reported and seen. Older examples of any given technology are often found. The locations listed are for the site where the earliest solid evidence has been found, but especially for the earlier inventions, there is little certainty how close that may be to where the invention took place.

Lower Paleolithic

The Lower Paleolithic period lasted over 3 million years, and corresponds to the human genus prior to the emergence of Homo sapiens. The original divergence between humans and chimpanzees occurred 13 (Mya), however interbreeding continued until as recently as 4 Ma, with the first species clearly belonging to the human (and not chimpanzee) lineage being Australopithecus anamensis. This time period is characterized as an ice age with regular periodic warmer periods – interglacial episodes. Some species are controversial among paleoanthropologists, who disagree whether they are species on their own or not. Here Homo ergaster is included under Homo erectus, while Homo rhodesiensis is included under Homo heidelbergensis.

• 3.3 Mya - 2.6 Mya: Stone tools - found in modern day Kenya are older and only found on the archetype road. Ancient stone tools from Ethiopia (Oldowan) were hand-crafted by Australopithecus or related people.^{[1][2][further explanation needed]}
• 2.3 Mya: Earliest likely control of fire and cooking, by Homo habilis^[3][4][5]
• 1.76 Mya: Advanced (Acheulean) stone tools in Kenya by Homo erectus^[6][7]
• 1.75 Mya - 150 kya: Varying estimates for the origin of language^[8][9]
• 1.5 Mya: Bone tools in Africa by Homo erectus^[10]

• 400 kya - 300 kya: Spears in Germany^[16][17] likely by Homo heidelbergensis

Middle Paleolithic

The dawn of Homo sapiens around 300 kya coincides with the start of the Middle Paleolithic period. Towards the middle of this 250,000-year period, humans begin to migrate out of Africa, and the later part of the period shows the beginning of long-distance trade, religious rites and other behavior associated with Behavioral modernity.

• 320 kya: The trade and long-distance transportation of resources (e.g. obsidian), use of pigments, and possible making of projectile points in Kenya^[18][19][20]
• 279 kya: Early stone-tipped projectile weapons in Ethiopia^[21]
• 200 kya: Glue in Central Italy by Neanderthals.^[22] More complicated compound adhesives developed by Homo sapiens have been found from c. 70 kya Sibudu, South Africa^[23] and have been regarded as a sign of cognitive advancement.^[24]
• 200 kya: Beds in South Africa.^[25][26][27]
• 170 kya - 83 kya: Clothing (among anatomically modern humans in Africa).^[28] Some other evidence suggests that humans may have begun wearing clothing as far back as 100,000 to 500,000 years ago.^[29]
• 164 kya - 47 kya: Heat treating of stone blades in South Africa.^[30]
• 135 kya - 100 kya: Beads in Israel and Algeria^[31]

• 61 kya - 62 kya: Cave painting in Spain by Neanderthal^[42]

Upper Paleolithic to Early Mesolithic

50 ka has been regarded by some as the beginning of behavioral modernity, defining the Upper Paleolithic period, which lasted nearly 40,000 years (though some research dates the beginning of behavioral modernity earlier to the Middle Paleolithic). This is characterized by the widespread observation of religious rites, artistic expression and the appearance of tools made for purely intellectual or artistic pursuits.

• 49 kya – 30 kya: Ground stone tools – fragments of an axe in Australia date to 49–45 ka, more appear in Japan closer to 30 ka, and elsewhere closer to the Neolithic.^[43][44]
• 47 kya: The oldest-known mines in the world are from Eswatini, and extracted hematite for the production of the red pigment ochre.^[45][46]
• 45 kya – 9 kya: Earliest evidence of shoes, suggested by changes in foot bone morphology in China by Tianyuan Man.^[47] The earliest physical shoes found so far are bark sandals dated to 10 to 9 kya in Fort Rock Cave, United States.^[48]
• 44 kya – 42 kya: Tally sticks (see Lebombo bone) in Eswatini^[49]
• 42 kya: Flute in Germany^[50][51]
• 37 kya: Mortar and pestle in Southwest Asia^[52]
• 36 kya: Weaving – Indirect evidence from Moravia^[53][54] and Georgia.^[55] The earliest actual piece of woven cloth was found in Çatalhöyük, Turkey.^[56][57]
• 33 kya - 10 kya: Star chart in France^[58] and Spain^[59]
• 28 kya: Rope^[60]
• 26 kya: Ceramics in Europe^[61]
• 23 kya: Domestication of the dog in Siberia.^[62]
• 22 kya: Fishing hook in Okinawa Island modern day Japan.^[63][64]
• 16 kya: Pottery in China^[65]
• 14.5 kya: Bread in Jordan^[66][67]

The end of the Last Glacial Period ("ice age") and the beginning of the Holocene around 11.7 ka coincide with the Agricultural Revolution, marking the beginning of the agricultural era, which persisted there until the industrial revolution.

Iron Age

The Late Bronze Age collapse occurs around 1300-1175 BC , extinguishing most Bronze-Age Near Eastern cultures, and significantly weakening the rest. This is coincident with the complete collapse of the Indus Valley civilisation. This event is followed by the beginning of the Iron Age. We define the Iron Age as ending in 510 BC for the purposes of this article, even though the typical definition is region-dependent (e.g. 510 BC in Greece, 322 BC in India, 200 BC in China), thus being an 800-year period.^{[nb 5]}
