hominid evolution - Essay ExampleThis is non the earliest of human sprightliness, though. Fossils prove that human-like creatures deliver lived on the satellite for millions of years. Thus the species that unexampled valet de chambre belong to has, in one form or another, been on background for a very long period. One of the most important questions to be answered, then, is why it is only modern humans that have managed to survive on earth. Why did other examples die out, and why did only humans such as those living today thrive and dominate all the species on earth? In the case of the Neanderthals, particularly, it is not simple to explain why they became extinct. For 200 000 years they dominated among species on the European continent. Only 28 000 years ago the last populations of the Neanderthals died out in Gibraltar, the last settlement comprehension has evidence of (Wong 2009 134). Only modern-form humans then continued to exist on earth. Theories to explain this veer in the population of earth range from climate change as the cause for this dying out, to theories of conquest of the Neanderthals by the moderns. Climate change may certainly have caused the Neanderthals to have to adapt continually to changing brave patterns and ecologies. This adaptation would have had to affect their hunting methods, their sources of shelter, and their sources of food. Wong (2009 135) proposes that the climate change experienced in Europe during the time of the Neanderthals was not gradual over a long period of time. From about 65 000 years ago to about 25 000 years ago, the climate changed completely in continental Europe. The period began with mild and restrained conditions across the continent, and ended with Europe experiencing extreme cold, snow and ice year-round. Evidence shows that this did not happen in stages it did not just get progressively colder over 40 000 years. Instead, the weather patterns and thus the environment would change completely in relatively short periods of time in one place. Plant and animal life could be completely replaced by new ecology within one Neanderthals lifetime, in one area. Therefore the Neanderthals would have to change their lifestyles completely in order to survive hunting methods where they lived the affable of shelter they needed and their food sources. Everything may very well have changed completely without warning. Hence the populations of Neanderthals would reduce, and not have time to recover before the next major climate change. Eventually over generations this may have led to populations too small to sustain themselves in particular areas (Finlayson in Wong 2009 135). It may to boot be that the migration of modern hominids into Europe and the near-East placed more pressure on available food resources. The Neanderthals, attempt to adapt to rapidly changing ecologies around them would have had further to compete for their traditional food sources with the newcomers. The bm of homo sapiens out of its African origin and gradually across the planet would certainly have had, then, some effect on the extinction of the Neanderthals. Living in Africa, modern hominids were taller and lighter than the Neanderthals. They needed slight food to survive and function than the Neanderthals they were hence adaptable they used more sophisticated tools and hunting blazonry (Gugliotta 2008 139). What explains their
