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 oer two million years ago , suggest that public were nomadic during the paleolithic era and lived in villages and switched to farming during the neolithic era . Technologies during the pre-historical period included crafts , and the lack of evidence of accomplishment leads researchers to suppose that science consisted of an abstract interest in spirit and that it was nearly 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 pursuit and scavenging and in processing animal and plant food . receivable to the nature of a society based on seasonal and migratory food collecting scientists believe there was gloomy surplus , which led to a diminished need for societal ranking , dominance , and coercive institutions which tax store , and redistribute surplus food . Researchers believe these societies were egalitarian , although there may have 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 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 span of the Paleolithic era race tightfistedness remained low due to longer periods of nursing , a officious lifestyle , and infanticide . Though the population was increasing , its rate of subjoin was one five-hundredth of what it would be for subsequent modern populations . As people migrated and spread across the earth , it wasn t until people had reached the southernmost tip of South America that population pressure against collectible resources lead to the shift 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 virtually the same way of life for such a long time , compared to more modern periods in history . Finally scientists would like to understand what led to the rapid acceleration that occurred toward the destination of the Paleolithic era that eventually resulted in a relatively quick shift to agriculture . One system is that dramatic climate change and the retreat of the glaciers at the end of the Ice Age led , resulting in the extinction of many large 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 enough for hunters and gatherers to exploit their local resources with relative ease . Since population growth was very slow , it may have taken nearly two million...If you want to get a liberal essay, order it on our website: Ordercustompaper.com
