What were the different types of prehistoric tools?

prehistoric stone tools were used during the paleolithic (age of old stone) that characterizes the period. Paleolitic dates back to 2.5 million years ago (mya), when the ancestors homo sapiens (early homonides, ie

paleolithic is divided into the lower paleolithic, medium paleolithic and upper paleolithic based on cultural trends, including the complexity of the tools. 300,000 years of age and upper paleolithic are not matching the end of the era, as people in different areas of the world have been doing cultural transitions at different times. The various stone tools are divided into four "modes" based on their sophistication. The first is mode 1 whose most famous example is the Oldowan A tools industryIt lasted from 2.5 mya to about 0.25 mya. Another industry in this category was Clactonian, who came much later (about 300,000), but was simplifying for time that homo erectus rather than modern people.

Mode 1 tools are simple helicopters and tools based on flakes such as scrapers, cleavage and primitive AWLS. They were made of any stone that could maintain the edge, were "unwavering" (edges made by several large slap, no huge efforts to be very sharp or straight) and relatively simplified, usually with only one processed edge (united). When they were found in Europe, the Oldowan tools were called Abbevillian and only Oldowanv Africa was found, but the name Oldowan was now admitted for both.

Mode 2 Stone Tools are part of the Acheulian industry, probably the most famous of the stone tool industrial industry oTwo because of their combination of age and relative sophistication. These are bifacial axes considered to be a critical division between older stone tools and newer stone tools. Generally, mode tool tools were used from about 1.65 mya to 100,000 years. They were Acheulian users who originally left Africa and colonized Europe about 1.5 mya.

Acheulian instruments are clear because it was valued by the cores in itself, rather than the flakes knocked the core. Soft hammers made of wood and bone were used to achieve greater control over the final product. Acheulian instruments made more effort and were probably used for a longer period of time, perhaps one of the first real "human assets". A urban man worthy of the environment in which he was forced to use stone tools, can think of the production of 2 stone tools.

3 Stone tool mode is characterized by being produced by levallois technique that included separation of the centerLing core to create a regularly shaped "levallois core", which was then carefully interrupted to create a "levallois point" - a number of sharp and regular stone tools that look almost as if they were made more rather than man. Short lithic blades were made. Mode 3 tools are most prominently linked to the non -standard Museterian industry in the middle paleolithic.

Stone tools of mode 4 are granular rocks such as basalt, and are produced by the grounding process by means of water to produce any shapes. Stone furniture found in flintstones would require the creation of MODE 4 technology. This way of creating tools has been accepted only a little before the advent of modern history, especially in neolithic places that existed since the arrival of agriculture for 10,000 years, until the Bronze Age, which began about 3,500 years ago.
