Technology And The Future (with The Past As A Guide)

TECHNICAL CHANGE THROUGH HISTORY AND PREHISTORYArtifacts from what scientists refer to as pre explanation , a time which they cerebrate took place over two million years ago , suggest that humanity were nomadic during the palaeolithic era and lived in villages and switched to farming during the neolithic era . Technologies during the pre-historical power point included crafts , and the lack of evidence of acquirement leads researchers to suppose that science consisted of an abstract interest in core and that it was close to non-existent , with exception of astronomy . Because tribe in the paleolithic era were thought to be hunters and gatherers , they crafted tools to aid them in sake and scavenging and in processing animal and plant fare . referable to the nature of a rescript based on seasonal plumper and migrat ory food collecting scientists deliberate there was murky surplus , which led to a diminished need for social ranking , dominance , and coercive institutions which tax store , and redistribute surplus food . Researchers believe these societies were egalitarian , although there whitethorn bewilder been divisions of power and status within groups . Scientists believe that in the Upper Paleolithic , spear-throwers and the bow and arrow were developed and wolves were domestic help and used to help with hunting . Over all archaeologists believe that Paleolithic people led relatively comfortable , same(predicate) lives and consumed a varied diet with significant amounts of meat and did non have to work too hard to sustain themselves It is believe that over the broom of the Paleolithic era race tightfistedness remained low due to vaster periods of nursing , a officious lifestyle , and infanticide . though the population was increasing , its rate of subjoin was one ordi nal of what it would be for subsequent moder! n populations . As people migrated and interpenetrate across the earth , it wasn t until people had reached the southernmost tip of confederation America that population pressure against collectible resources lead to the channel from hunting and crowd to horticulture and agriculture (McClellan , 2006 pp .

6-12Because the Paleolithic era is though to have lasted for tens of thousands of years , scientists are highly interested in understanding the lack of technological forward motion during this period . They want to know why Paleolithic people lived more or less the same way of life for such a long time , com pared to more modern periods in history . at long last scientists would like to understand what led to the rapid acceleration that occurred toward the term of the Paleolithic era that eventually resulted in a relatively quick shift to agriculture . One system is that melodramatic climate change and the retreat of the glaciers at the end of the meth Age led , resulting in the extinction of many commodious animals the northward migration of many other animals . Humans may have also over-hunted large animals themselves , thereby leading to a food shortage . Another theory suggests that the hunting and gathering society persisted for as long as the population remained small copious for hunters and gatherers to exploit their local resources with relative ease . Since population product was very slow , it may have taken nearly two million...If you want to get a liberal essay, rank it on our website: OrderCustomPaper.com
