Dec. 10, 2007 Countering a common theory that human evolution has slowed to a crawl or even stopped in modern humans, a new study examining data from an international genomics project describes the past 40,000 years as a time of supercharged evolutionary change, driven by exponential population growth and cultural shifts. Anthropologist John Hawks estimates that positive selection in the past 5,000 years has occurred at a rate roughly 100 times higher than any other period of human evolution. His research is based on analysis of international genetic data that provides evidence of recent positive selection.

Humans Evolving More Rapidly Than Ever, Say Scientists | Wired S
Look out, future, because here we come: scientists say the speed of human evolution increased rapidly during the last 40,000 years — and it’s only going to get faster. The findings, published today by a team of U.S. anthropologists in the Proceedings of the National Academy of Sciences , overturn the theory that modern life’s relative ease has slowed or even stopped human adaptation. Selective pressures are still at work; they just happen to be different than those faced by our distant ancestors. "We’re more different from people 5,000 years ago than they were from Neanderthals," said study co-author and University of Utah anthropologist Henry Harpending. In the study, researchers analzyed genomes from 270 people belonging to four disparate ethnic groups: Han Chinese, Africa’s Yoruba tribe,
Psychology Today: Ten Politically Incorrect Truths About Human N
Human nature is one of those things that everybody talks about but no one can define precisely. Every time we fall in love, fight with our spouse, get upset about the influx of immigrants into our country, or go to church, we are, in part, behaving as a human animal with our own unique evolved nature—human nature. This means two things.[Journalists] seem to feel let down when they discover that the real people aren't anything like the way they so relentlessly portray us; as if, since they've gone to the trouble of inventing extravagant caricatures of us, we should at least have the decency to live up to them in real life.

Abstract On the basis of the technical definition of selection developed by George Price (1995), we describe two forms of selection that commonly occur at the social level, subset selection and generative selection. Both forms of selection are abstract and general, and therefore also incomplete; both leave aside the question of explaining the selection criterion and why entities possess stable traits. However, an important difference between the two kinds of selection is that generative selection can accommodate an explanation of how new variation is created, while subset selection cannot. An evolutionary process involving repeated cycles of generative selection can, in principle, continue indefinitely because imperfect replication generates new variation along the way, whereas subset selection reduces variation and eventually grinds to a halt. Even if the two kinds of selection examined here are very different, they share a number of features.

The descendants of the genetic upper class would be tall, slim, healthy, attractive, intelligent, and creative and a far cry from the "underclass" humans who would have evolved into dim-witted, ugly, squat goblin-like creatures. Race 'ironed out' But in the nearer future, humans will evolve in 1,000 years into giants between 6ft and 7ft tall, he predicts, while life-spans will have extended to 120 years, Dr Curry claims.Differential Evolution grew out of Ken Price's attempts to solve the Chebychev Polynomial fitting Problem that had been posed to him by Rainer Storn. A breakthrough happened, when Ken came up with the idea of using vector differences for perturbing the vector population. Since this seminal idea a lively discussion between Ken and Rainer and endless ruminations and computer simulations on both parts yielded many substantial improvements which make DE the versatile and robust tool it is today.

the Face of Tomorrow: the Human Face of Gl
The large metropolises of the world are magnets for migrants from all parts of the planet resulting in new mixtures of peoples. What might a typical inhabitant of this new metropolis look like in one or two hundred years if they were to become more integrated? In Turkey and particularly in Istanbul, situated as it is at the crossroads of Europe and Asia, of the Mediterranean and the Black Sea, you can see how this process has been at work over the last thousand years as waves of humanity from Central Asia, Arabia, Greece and Rome have been absorbed. The resulting population is fairly uniform suggesting that if you could combine all the faces in a city right now you would be looking at the future face of that city.Public release date: 23-Jul-2006 [ Print | E-mail | Share ] [ Close Window ] NIH/National Institute on Deafness and Other Communication Disorders

And so you're sick of the look of walls of your house or at your work place? You should not purchase high-priced original art pieces to create sophisticated interior: with several good framed posters you can renew your interior. Still life reproductions or recipe posters are excellent for kitchen, marine motifs would be acceptable for bathing room, large wide-angled landscape pictures are great additions for small windowless rooms. Motivational pictures can put you in good mood whenever you are feeling tired and sad. Several properly selected funny posters or motivational pictures will create friendly and warm atmosphere for you and your co-workers in your office. If you've got certain favorite period of movies or music history, you may recreate an inimitable ambiance in one of interior zones by placing a collage of retro posters with photographs of well-known celebrities of certain period.
