A variety of stone tools During most of the Paleolithic - the bulk of the Stone Age - all humans had a lifestyle which involved limited tools and few permanent settlements. The first major technologies were tied to survival, hunting, and food preparation. Stone tools and weapons, fireand clothing were technological developments of major importance during this period.
Human ancestors have been using stone and other tools since long before the emergence of Homo sapiens approximatelyyears ago. To make a stone tool, a " core " of hard stone with specific flaking properties such as flint was struck with a hammerstone.
This flaking produced sharp edges which could be used as tools, primarily in the form of choppers or scrapers.
In the Acheulian era, beginning approximately 1. This early Stone Age is described as the Lower Paleolithic. The Middle Paleolithicapproximatelyyears ago, saw the introduction of the prepared-core techniquewhere multiple blades could be rapidly formed from a single core stone.
The Mesolithic technology included the use of microliths as composite stone tools, along with wood, bone, and antler tools. The later Stone Age, during which the rudiments of agricultural technology were developed, is called the Neolithic period.
During this period, polished stone tools were made from a variety of Time traveling art historian rocks such as flintjadejadeiteand greenstonelargely by working exposures as quarries, but later the valuable rocks were pursued by tunneling underground, the first steps in mining technology.
The polished axes were used for forest clearance and the establishment of crop farming and were so effective as to remain in use when bronze and iron appeared.
These stone axes were used alongside a continued use of stone tools such as a range of projectilesknives, and scrapersas well as tools, made organic materials such as wood, bone, and antler.
Stone Age humans developed ocean-worthy outrigger canoe technology, leading to migration across the Malay archipelagoacross the Indian Ocean to Madagascar and also across the Pacific Ocean, which required knowledge of the ocean currents, weather patterns, sailing, and celestial navigation.
Although Paleolithic cultures left no written records, the shift from nomadic life to settlement and agriculture can be inferred from a range of archaeological evidence.
Such evidence includes ancient tools,  cave paintingsand other prehistoric artsuch as the Venus of Willendorf. Human remains also provide direct evidence, both through the examination of bones, and the study of mummies.
Scientists and historians have been able to form significant inferences about the lifestyle and culture of various prehistoric peoples, and especially their technology. The Neolithic Revolution involved radical changes in agricultural technology which included the development of agricultureanimal domesticationand the adoption of permanent settlements.
These combined factors made possible the development of metal smeltingwith copper and later bronzean alloy of tin and copper, being the materials of choice, although polished stone tools continued to be used for a considerable time owing to their abundance compared with the less common metals especially tin.
This technological trend apparently began in the Fertile Crescent and spread outward over time. These developments were not, and still are not, universal. The three-age system does not accurately describe the technology history of groups outside of Eurasiaand does not apply at all in the case of some isolated populations, such as the Spinifex Peoplethe Sentineleseand various Amazonian tribes, which still make use of Stone Age technology, and have not developed agricultural or metal technology.
It generally replaced bronze and made it possible to produce tools which were stronger, lighter and cheaper to make than bronze equivalents. In many Eurasian cultures, the Iron Age was the last major step before the development of written language, though again this was not universally the case.
It was not possible to mass manufacture steel because high furnace temperatures were needed, but steel could be produced by forging bloomery iron to reduce the carbon content in a controllable way.Program Successes.

Is Western Civilization in Decline? I think nearly everyone in the manosphere would agree that it is. There is a lot of discussion these days about America and the other nations comprising Western Civilization being in decline, and there is certainly a lot of evidence to support this claim.
