Is human evolution has finally stopped? For those who dream of a better life drop of bad news: the best condition in which the head is not going to be any better. We reached the peak of its biological species and can not be changed. This view is dark and controversial group of biologists who believe Western lifestyle of humanity against the forces that shape Homo sapiens to protect itself. Professor Steve Jones (S.Jones) from University College London next week at a meeting of the Royal Society of Edinburgh as “the evolution to an end?” Arguments suggest, says, “If you want to know what it’s like Utopia, Take a look around and around. That is why you see utopia. For any of the following things will not get worse, not better. “But this view is controversial. Other scientists believe that humans are influenced by the evolutionary forces that have created over the past three billion years myriad species that inhabited the earth acting on. Professor Chris Stringer (C.Stringer) of the Natural History Museum in London, “said the 50 thousand years ago, if you had looked into the Stone Age Europeans, people always thought would be bigger and stronger. But then, quite abruptly, people light, tall, highly intelligent, who had come from Africa, where they were and took over the world. Evolutionary events like this simply can not predict. Who knows where we are headed? “Some scientists believe that humans are Kmhvshtr and Sbytr. Some see signs of growing intelligence and decreasing robustness, while others, like Jones, see evidence that we have reached a standstill. All their arguments are based on the principle of natural selection is made. This process of evolutionary changes. For example ungulate animals with longer necks could reach the Bdartryn leaves on tall trees and thus usually fed better, live longer and have more offspring. Eventually evolved into giraffes and extinct ones with shorter necks. Similar processes led to the evolution of man, but this has now stopped because almost all of the genes to the next generation, and not only those genes with their environments Sazshyafthand better. Jones says, “Until recently, there were significant differences between longevity and fecundity of individuals. In London, the bulk of the city’s history, the death rate was higher than the birth rate. If you look at graveyards from ancient times to the Victorian era, you can see that half of all children died before reaching adolescence, probably because of the lack of genetic protection against disease. All children are likely to reach the age of 25 to 98 percent. Nothing is changing. We reached the station. “Furthermore, the human population is constantly mixed, again blending that blocks evolutionary change. The mixing can be increased by calculating the distance between a person’s birthplace and the home of his wife and parents, and eventually became the home of their grandparents. In almost all cases, you will discover that the return to the distance between the home less. Now people go to universities and colleges with people from other continents meet and marry. A generation ago, men and women rarely married to someone from a different town or city. We were pooled, and the genes that soon people will rise evenly with brown skin. Apart from this, there will be little change in the species. But this argument applies only to the West civilized world where food, hygiene and medical advances, almost all members of the community alive who can pass their genes to the next generation. In the developing countries there is no such protection. Jones says, “AIDS is sufficient to consider and look at chimpanzees. You find them all with their version of HIV but not AIDS. But a few years ago when the chimps became infected, the situation was very different. Likely to spread among millions of chimpanzees died and only a few of them that were in the immunity genes, all Shmpanz·hhay ancestors survived until today. “Jones added,” Something very similar could soon happen to humans. In a thousand years, Africa will be only the descendants of those few individuals who are already immune to the virus. They will carry the virus but not HIV. came. For example, Christopher Wills (C.Wills), a biologist at the University of California at San Diego, argues that ideas are now driving our evolution. He says, “now points to a sharp mind and the ability to accumulate money there and the evolution of the reward. Such people tend to have more children and are more likely to survival. “In other words, intelligence is the defining characteristic of our species still driving our evolution. Peter Ward (P.Ward) from the University of Washington in Seattle, disagrees with this view. Enter the recent book entitled “Future Evolution” has been published, argues that modern Western life protects people from the effects of evolution. Enter saying “I did not change in the future, except those who deliberately create ourselves. its consequences will be dramatic. ‘People will produce dozens of children in her lifetime, and it certainly began our evolution will be derailed. These individuals will be given more opportunities to accumulate wealth. So we created a new race of people will be fruitful and productive and this can have dramatic consequences. But that will only happen when we use the cloning and gene therapy directly intervene in our own evolution. Otherwise nothing will happen. “But Stringer opposite. ‘Evolution goes on. You do not have to intervene. Only the highly unpredictable. For example, brain size has decreased in the past 10 years. A similar reduction in our physiques happened. Compared to our ancestors who lived just a few thousand years ago, the Ryzandamtr we also have smaller brains. So even though we’re influenced by evolution, it does not automatically mean that our destiny is in progress. “
