Neanderthal Brain Size At Birth - 1718 Words

nbsp;nbsp;nbsp;nbsp;nbsp;nbsp; In the article, quot;Neanderthal Brain Size at Birth Provides Insights into the Evolution of Human Life Historyquot; by Marcia S. Ponce de Leon discussed human life history is characterized by an extended period of developmental immaturity. This pattern of ontogeny is thought to be necessary for higher cognitive capabilities (Ponce de Leon 37). However, recent studies suggest the differences between the human brain growth and the chimpanzees are less evident (Ponce de Leon 37). Humans reach their large adult brains by means of higher growth rates early during ontogeny (Ponce de Leon 37). With that being said, large adult brains are connected with slow life histories (Ponce de Leon 37). Even so, the†¦show more content†¦Yet, there hasnapos;t been any indication of an increase in intelligence (Henneberg 745). In modern humans, brain size and intelligence is very weak (Henneberg 745). With the exception of size, there appears to be no significant dissimilarities between the anatomy of ape and human brains (Henneberg 745).nbsp; nbsp;nbsp;nbsp;nbsp;nbsp;nbsp; In addition, the macro evolutionary enlargement of the hominid brain correspond with other mammals and body size (Henneberg 748). The micro evolutionary decrease in human brain size during intellectual and cultural achievement (Henneberg 748). The lack of intraspecfic correlation between brain size and measured human intelligence is not in result of its size (Henneberg 748). It is also probably not in result of its gross anatomical structure (Henneberg 748). Human encephalization may be more a result of the reduction in the relative body size as opposed to the increase in brain size (Henneberg 748). nbsp;nbsp;nbsp;nbsp;nbsp;nbsp; In the article, quot;Brain ontogeny and life history in Homo erectusquot; by Steven R. Leigh discussed Homo erectus provided meaningful insights about the evolution of human ontogeny, life history, as well as cognition. The similarity between hominins is determined by testing three hypotheses (Leigh 105). With that being said, Mojokertoapos;s absolute brain size is expected to be 0.5 - 1.5 year old H. sapiens (Leigh 105). The cranialShow MoreRelatedChanges Of Climate Change Across Earth1561 Words   |  7 Pageshowever, it is hard to prove this hypothesis as new fossils are found (p. 236). While H. erectus characteristics vary across continents, the majority share the same range in body size, brains, and cranial shape. H. erectus adults had robust bodies weighing more than 100 lbs. and measuring 5’6† tall. The range in H. erectus brain size is 700 to 1250 cm(^3). The most distinct characteristic of H. erectus is its cranial shape. The cran ium displays a thick cranial bone, large brow ridges, a pointy nuchal torusRead MoreComplication Of Birth.1575 Words   |  7 PagesComplication of birth nbsp;nbsp;nbsp;nbsp;nbsp; Throughout the years, our brain shape has changed in result of the nutrition received. The amount of nutrition received is the biggest factor with regard to the change in brain size. Therefore, the sufficient nutrition increased the size of the brain. In result, the increased brain size created advanced cognitive functions. Culture nbsp;nbsp;nbsp;nbsp;nbsp;nbsp; In chapter eight quot;Early Hominisquot; of the textbook, quot;IntroductionRead MoreFactors in the Evolution to Bipedalism766 Words   |  4 Pagesspecies has significantly changed during the course of evolution to what is now the modern day Homo sapiens. Some of the changes that have occurred through the evolution are bipedalism, changes in body features such as brow ridges, and an increase in brain capacity. Bipedalism is a form of locomotion that is on two feet and is the one factor that separates humans from other forms of hominoids. The first bipeds are believed to have lived in Africa between 5 and 8 million years ago. (HavilandRead MoreSimilarities Between Neanderthals And Modern Humans Essay2071 Words   |  9 PagesNeanderthals were a species of archaic humans who migrated out of Africa and into Europe and Asia. However, around 40,000 years ago the large populations of Neanderthals died off and became extinct. The mysterious circumstances that surrounded their extinction drove various research teams to undertake the task of excavating numerous Neanderthal sites to collect fossilized bones, and artifacts in order to learn more about this group of ancestral humans. Over the past years, major technological advancesRead MoreAnalysis Of The Movie Iceman The Neanderthal 1227 Words   |  5 PagesNeanderthal Prejudice Elizabeth Armistead When humans encounter other humans, we tend to treat them differently. Whether it’s because of cultural barriers, language barriers, or something as trivial as skin color, we view some people differently than we view those who share our ethnicity, culture, and values. This is referred to as racism or prejudice and it is still an active problem in the world today. But although people can differ greatly when it comes to culture or appearance, we share mostRead MoreAncient History: Neanderthals to Homosapiens1957 Words   |  8 Pages NEANDERTHALS TO HOMOSAPIENS Neanderthal the most recent archaic human, who was introduced to this world between 300,00 and 100,000 years ago then after many years were replaced by humans between 35,000 and 24,000 years ago. Neanderthals inhabited Eurasia from the Atlantic regions of Europe eastward to Central Asia and from as far north as present-day Belgium southward to the Mediterranean and southwest Asia.† (www.britannica.com). Human populations that were very similar to Neanderthals lived inRead MoreEnvironmental Factors Affecting Human Evolution Essay1628 Words   |  7 PagesGenetic mutations appeared in cases that led to the birth of new species by creating further genetic differences that allows more of a kind of species to survive by increase the chances of producing offspring and give adaptations to survive based around a new habitat. Furthermore, responses to environmental factors show that records of some organisms responded by creating change to their environments instead of themselves. Huma ns, with larger brains than other animals, have shown to do this substatiallyRead MoreHomo Neanderthalensis- the Neanderthals3667 Words   |  15 PagesSince their discovery more than a century ago, the Neanderthals have hovered over the minds and have baffled the best-laid theories of paleoanthropologists. They seem to fit in the general scheme of human evolution, and yet they’re misfits. (Jurmain, Kilgore, Trevathan and Ciochon. p.367) In a way they are like us the modern Homo sapiens but yet are a very different species. But the real question that needs to be answered is â€Å"why the Neanderthals were considered a different species than the Homo sapiensRead MoreAncient Civilizations And The Modern World1379 Words   |  6 Pagesand humans have adapted to their surroundings. All living things have changed throughout time. The thing that differs humans from the rest is, humans are more cognitively advanced. Over the course of time the shape and size of the human skull ha ve changed. The size of the human brain has increased, which has allowed humans to adapt more to their surroundings. To survive, humans were making tools for hunting and to cut with. The closer you lived to the equator the darker your skin may have been, soRead MoreAnalysis Of The Article History Of Technology By Robert Angus Buchanan1012 Words   |  5 PagesSebastian Arias From the birth of the first single celled organism, to the first dated appearance of the neanderthal, life has been constantly evolving to achieve a greater sense of survival and adaptation. We as human beings have become a prime example of the evolutionary process surpassing the predators which once preyed upon us to becoming the top of the food change. Although our evolution is an amazing feat we have used the knowledge of billions of years of evolution to create something
