Stem cells and cloning technology will impact the evolutionary process in the future, once the natural selection is expelling, human Holden in what is right or doom? recently, Korea Seoul National University, visiting Professor Hwang Woo-Suk's difficult patients by cloning of somatic, successfully nurtured embryonic stem cells, in the world to expand the therapeutic cloning research competition, a step in the lead. It is through similar efforts, human beings trying to make ourselves could not be destroyed. Although the natural evolution of the clock never ceased, but in fact mankind has become a driving force of its own evolution. Mankind is in which direction the future in the development of evolutionary theory in the book, Washington University's paleontologists Peter · Ward pointed out that, according to their own will distort the plants and animals on Earth, in fact we are become unable to be extinct. Assuming that the mankind will in future continue to 5 million years of existence, Ward, who believe that humanity is moving in the direction of the following five:
A single person (Unihuman): we will be assimilated?
Biologists have pointed out, a species of different populations must be isolated in order to cause these populations towards different species differentiation. This is the Galapagos Islands has 13 different "Darwin's finches". Earth link between human beings is becoming more and more closely, this will not cause human no opportunity for differentiation? there is no doubt that the theory of evolution will still work, but in the last ten thousand years, the human gene pool not diverge rather in convergence. Duke University's biodiversity expert Stewart · bhim pointed out that this trend is likely to increase. The variability of the "gene can protect us when some virus attack time is not affected by the large-scale damage. "However, with the development of globalization, ethnic differences are disappearing," we have become like animals in a single culture ", the human may be more vulnerable to the impact of infectious diseases.
The surviving people (Survivalistian): to cope with the end of the world
Maybe it was a nuclear war or asteroid impact Earth ...... This global destruction disaster occurred, the remnants of humanity are separated in some corners of the world, again faced with natural selection. If different people isolated development over thousands of generations, you can imagine, different people will appear. In science fiction, this is a very tempting outstanding issues. This may occur for one of the classic description should be H · G · Wales's "time machine", which in the wake of a catastrophe after the Earth, human beings are divided into two races: gentle and beautiful ILOG people and live in underground merciless Mo Nintendo. It is difficult to imagine that even a global disaster, different people will separate enough long let us make differentiation of species. "Unless we totally forgot how to shipbuilding, we'll get together soon. "Ward says. Even after the man really break, evolutionary theory shows a species will eventually conquered, assimilation or eliminate their competitors, thereby in the global ecosystem is in the highest position.
Newcomer (Numans): the rise of Superman
Scientists are constantly find new gene and pharmacological approaches to strengthening human, and the development of these areas can be quickly as a new form of evolution, it may take millions of years of biological evolution much faster. Then, the evolution of new wave led to a new kind of birth how long does it take? "try 20 years," forthcoming in the radical evolution, "a book's author community observers Joel · Caroline says. From steroids build muscle men to allow soldiers to stay a few days several night neither eat nor sleep pill, Caroline pointed out that the technology for human enhancement originally appeared in the sports ground and battle, but ultimately it will go into the lives of ordinary people. "The future of humanity will be divided into 3 types: strengthening human, natural and otherwise remaining. "Caroline believes that strengthening the people who have money and want to let their longer life, more clever, more sexy, natural persons are those who refuse to noble aims to strengthen the role of the person, is like refusing meat vegetarians; the rest are those who do not have the capacity to strengthen their own people. Imagine after hardening, you also want your descendants also has the advantage of these enhanced, in such circumstances, you will not let your descendants passed with no such gene to artificially create a reproductive isolation environment that ultimately lead to a new generation of human kind.
Half robot (Cyborgs): combination with the machine
The rapid development of artificial intelligence for some experts worried that someday it will surpass human wisdom of nature. Deep blue computer beat chess champion ksparov is a striking example of this. However, in fact, we own a half robot seems more likely, because we are already making some body assimilates machinery such as prosthetics, artificial heart, artificial retina. "The General possibility is that we will be implanted in the brain, we will no longer be lost, can answer all used to haunt our math problem," Institute for extraterrestrial intelligence exploration of senior astronomer Seth Shostak · said. But Shostak believes that the combination of man and machine is only a transition, "you can pass in a horse's body mounting four-cylinder engine to make its acceleration, but ultimately do not need a horse can be, this hybrid varieties is not a great breakthrough, it only means that the machine is not good enough. ”
Astronomy (Astrans): become alien species
If human beings can live long enough, there is a possibility that the expansion to other planets in the formation of new species. This requires a similar Galapagos Islands environment — and close enough to the Earth, so that humans can reach far enough; and the Earth, the less likely and matriarchal species gene mix. Imagine, if human beings in the establishment of permanent residence of Mars, and the planet completely different living environments will be able to change the evolution of equality, for example, just 1/3 of the Earth's gravity environment was born and grew up in people came to the Earth may will not have the feeling of home
That doesn't take long Mars human will become a new species.
