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 ...
Stone tool use – early human (hominid) use of stone tool technology, such as the hand axe, was similar to that of primates, which is found to be limited to the intelligence levels of modern children aged 3 to 5 years. Ancestors of homo sapiens (modern man) used stone tools as follows: Homo habilis ("handy man") – first "homo" species.
1974 – China creates the first hybrid rice. [5] See Yuan Longping. 2000 – Genetically modified plants cultivated around the world. 2005 – Lasers used to replace stickers by writing on food to "track and trace" and identify individual pieces of a fresh fruit. [6]
The Clovis culture is an archaeological culture from the Paleoindian period of North America, spanning around 13,050 to 12,750 years Before Present (BP). [1] The type site is Blackwater Draw locality No. 1 near Clovis, New Mexico, where stone tools were found alongside the remains of Columbian mammoths in 1929. [2]
The Stone Age is a broad prehistoric period during which stone was widely used in the manufacture of implements with a sharp edge, a point, or a percussion surface. The period lasted roughly 2.5 million years, from the time of early hominids to Homo sapiens in the later Pleistocene era, and largely ended between 6000 and 2000 BCE with the advent of metalworking.
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 made from bone, wood, or other organic materials were therefore in all probability used before the Oldowan. [ 15 ]
An adze (/ æ d z /) or adz is an ancient and versatile cutting tool similar to an axe but with the cutting edge perpendicular to the handle rather than parallel. Adzes have been used since the Stone Age. They are used for smoothing or carving wood in hand woodworking, and as a hoe for agriculture and horticulture. Two basic forms of an adze ...
The control of fire by early humans was a critical technology enabling the evolution of humans. Fire provided a source of warmth and lighting, protection from predators (especially at night), a way to create more advanced hunting tools, and a method for cooking food.
