Timeline of historic inventions


The timeline of historic inventions is a chronological list of particularly important or significant technological inventions and the people who created the inventions.
Note: Dates for inventions are often controversial. Sometimes inventions are invented by several inventors around the same time, or may be invented in an impractical form many years before another inventor improves the invention into a more practical form. Where there is ambiguity, the date of the first known working version of the invention is used here.
A proportion of all discoveries within the United States made during the 20th and 21st centuries were made within skunk work enterprises.

Paleolithic

The dates listed in this section refer to the earliest evidence of an invention found and dated by archaeologists. Dates are often approximate and change as more research is done, reported and seen. Older examples of any given technology are found often. 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 species prior to the emergence of Homo sapiens. The original divergence between humans and chimpanzees occurred 13, however interbreeding continued until as recently as 4 Ma, with the first species clearly belonging to the human lineage being the Australopithecus anamensis. This time period is characterized as an ice age with regular periodic warmer periods – interglacial episodes.
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.
50 ka has been regarded by some as the beginning of Behavioral modernity, defining the Upper Paleolithic period, which lasted nearly 40,000 years. This is characterized by the widespread observation of religious rites, artistic expression and the appearance of tools made for purely intellectual or artistic pursuits.
The end of the Last Glacial Period and the beginning of the Holocene around 11.7 ka coincide with the Agricultural Revolution, marking the beginning of the agricultural era, which persisted until the industrial revolution.

Neolithic and Late Mesolithic

During the Neolithic period, lasting 8400 years, stone remained the predominant material for toolmaking, although copper and arsenic bronze were developed towards the end of this period.
The beginning of bronze-smelting coincides with the emergence of the first cities and of writing in the Ancient Near East and the Indus Valley. The Bronze Age is taken as a 2000-year long period starting in 3300 BC and ending in 1300 BC.
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, thus being an 800-year period.
It's worth noting the uncertainty in dating several Indian developments between 600 BC and 300 AD, due to the tradition that existed of editing existing documents without specifically documenting the edit. Most such documents were canonized at the start of the Gupta empire.
