Charles Darwin months just ended. Fanfare in celebration of 200 years of birth and 150 years of the emergence of phenomenal book, The Origin of Species, began gradually quiet. While cleaning the remnants of the party, curiosity about the future had crept up: whether human evolution is over as the fate of this celebration?
Anyone who holds fast to the idea of Darwin should have refused to agree to that question. Organic evolution is a certain event, just as surely as the earth around the sun. No creature can escape. Diversity, exists, or the extinction of a species entirely determined by natural selection, the prime mover of evolution, and it also applies to Homo sapiens.
The average survival of a species reaches a few million years. Every year, thousands of species declared extinct, and thousands more come to replace. There is no guarantee whether the human future can avoid both these facts.
The unique number of believers in Darwinian argues precisely the opposite. Human beings are too different that can not be equated with other species. Humans have the advantage in technology, energy regulation, the use of clothing, social organizations, and high-level language skills. In short, humans are the only species able to avoid evolution.
One of the arguments presented by the famous Steve Jones in a debate entitled Is Evolution Over? the Royal Society of Edinburgh seven years ago, "If you want to know what kind of utopia, just look around. The situation is better or worse has been stopped for our species."
Jones's argument is supported fully by Peter Ward, a renowned scientist in charge at the University of Washington. Through Future Evolution (2001), Ward did not see the changes would hit people. Current lifestyle, particularly in developed countries, have been protecting humans from evolutionary pressures.
"People can now live longer, stronger, and healthier," he wrote.
Several other experts chose a safer path. They consider human evolution still continues. Not in the physical level, but a culture. Looking ahead, significant changes occur only in areas of behavior, social trends, and intelligence.
Counterclockwise flow came from Chris Stringer is working in the Natural History Museum, London. According to him, too naive if people think that he is worth far more special in the face of natural selection than other species.
"If you listen back to the Stone Age people in Europe about 50 thousand years ago (Homo neanderthalensis), you would assume they will evolve into larger and stronger. Then, quite suddenly, they were just unable to compete and be replaced by species lighter-bodied, high, and more intelligent berdiaspora from Africa (Homo sapiens). You can not predict which direction evolution will drive, "said Stringer.
Notice of Stringer increasingly apparent with the publication of The 10.000 Year Explosion: How Civilization Accelerated Human Evolution by Gregory Cochran and Henry Harpending. In a new book that was a month old, stated that since the invention of agriculture and urban communities mencuatnya, humans have evolved 100 times faster.
Although still hotly debated, the data is at least showing progress and the resulting technology does not necessarily protect people from the jaws of natural selection. We do not know what's waiting up ahead, but that does not mean we are safe from species evolution.
The idea that we can create is great, our technologies also reveal remarkable sophisticated. However, all creatures must still comply with the Second Law Orgel: "Evolution is cleverer than you all."
