The timeline of historic inventions is a chronological list of particularly important or significant technological inventions and their inventors, where known.

Paleolithic

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, during which there many human-like species evolved including toward the end of this period, 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. 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.

During this period the Quaternary glaciation began (about 2.58 million years ago), and continues to today. It has been an ice age, with cycles of 40–100,000 years alternating between long, cold, more glaciated periods, and shorter warmer periods – interglacial episodes.

• 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.

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, archaic humans such as Neanderthals and Denisovans began to spread out of Africa, joined later by Homo sapiens. Also late in the period, we have increased evidence of long-distance trade, religious rites, and other behavior associated with Behavioral modernity.

• 200 kya: Beds in South Africa.
• 170 kya – 90 kya: Clothing, among anatomically modern humans in Africa. Genetic evidence from body lice suggests a range of dates centering over 100 thousand years ago. The first bone scrapers appropriate for scraping hides to make supple leather were found in Morocco dating to 90–120,000 years ago.
• 164 kya – 47 kya: Heat treating of stone blades in South Africa.
• 135 kya – 100 kya: Beads in Israel and Algeria

  • Sewing needle
• 61 kya – 62 kya: Cave painting in Spain by Neanderthal
• 55.8–51.2 kya: Representational and Narrative art in Indonesia by Homo sapiens

Upper Paleolithic to Early Mesolithic

50 kya was long regarded as the beginning of behavioral modernity, which defined the Upper Paleolithic period. The upper Paleolithic lasted nearly 40,000 years, while research continues to push the beginnings of behavioral modernity earlier into the Middle Paleolithic. Behavioral modernity is characterized by the widespread observation of religious rites, artistic expression and the appearance of tools made for purely intellectual or artistic pursuits.

Agricultural and proto-agricultural eras

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.

Neolithic and Late Mesolithic

During the Neolithic period, lasting 8400 years, stone began to be used for construction, and remained a predominant hard material for toolmaking. Copper and arsenic bronze were developed towards the end of this period, and of course the use of many softer materials such as wood, bone, and fibers continued. Domestication spread both in the sense of how many species were domesticated, and how widespread the practice became.

Iron Age

The Late Bronze Age collapse occurs around 1200 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.

Notes

1. 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.
2. Earthen pipes were later used in the Indus Valley c. 2700 BC for a city-scale urban drainage system, and more durable copper drainage pipes appeared in Egypt, by the time of the construction of the Pyramid of Sahure at Abusir, c.2400 BCE.
3. Shell, Terracotta, Copper, and Ivory rulers were in use by the Indus Valley civilisation in what today is Pakistan, and North West India, prior to 1500 BCE.
4. A competing claim is from Lothal dockyard in India, constructed at some point between 2400-2000 BC; however, more precise dating does not exist.
5. The uncertainty in dating several Indian developments between 600 BC and 300 AD, due to the tradition that existed of editing existing documents (such as the Sushruta Samhita and Arthashastra) without specifically documenting the edit. Most such documents were canonized at the start of the Gupta empire (mid-3rd century AD).
6. A 10th century AD, Damascus steel blade, analysed under an electron microscope, contains nano-meter tubes in its metal alloy. Their presence has been suggested to be down to transition-metal impurities in the ores once used to produce Wootz Steel in South India.
7. Although it is recorded that the Han dynasty (202 BC – AD 220) court eunuch Cai Lun (born c. 50–121 AD) invented the pulp papermaking process and established the use of new raw materials used in making paper, ancient padding and wrapping paper artifacts dating to the 2nd century BC have been found in China, the oldest example of pulp papermaking being a map from Fangmatan, Gansu.

"we present dating results for three sites in Spain that show that cave art emerged in Iberia substantially earlier than previously thought. Uranium-thorium (U-Th) dates on carbonate crusts overlying paintings provide minimum ages for a red linear motif in La Pasiega (Cantabria), a hand stencil in Maltravieso (Extremadura), and red-painted speleothems in Ardales (Andalucía). Collectively, these results show that cave art in Iberia is older than 64.8 thousand years (ka). This cave art is the earliest dated so far and predates, by at least 20 ka, the arrival of modern humans in Europe, which implies Neandertal authorship."

Joshi and Parpola (1987) lists a few pots tapered at the bottom and having a hole on the side from the excavations at Mohenjadaro (Figure 3). A pot with a small hole to drain the water is very similar to clepsydras described by Ohashi to measure the time (similar to the utensil used over the lingum in Shiva temple for abhishekam).

He then filled it with ink and wrote with it, and it really did write. The pen released a little more ink than was necessary. Hence al-Mu'izz ordered that it should be adjusted slightly, and he did this. He brought forward the pen and behold, it turned out to be a pen which can be turned upside down in the hand and tipped from side to side, and no trace of ink appears from it. When a secretary takes up the pen and writes with it, he is able to write in the most elegant script that could possibly be desired; then, when he lifts the pen off the sheet of writing material, it holds in the ink. I observed that it was a wonderful piece of work, the like of which I had never imagined I would ever see.

The authors wish to thank a number of colleagues for helpful comments during early discussions of international network protocols, especially R. Metcalfe, R. Scantlebury, D. Walden, and H.

Its simplicity and efficiency pointed the way to a network that could connect not just dozens of machines, but millions of them. It captured the imagination of Dr Cerf and Dr Kahn, who included aspects of its design in the protocols that now power the internet.
