The biological process that led to the emergence of intelligent life on Earth occurred serendipitously. Professor Brian Cox believes that such could hardly be repeated anywhere 'no Aliens, we are alone in the Universe' .
British physicist Brian Cox calls a miracle appearance of humanity as a result of the merger of two separate cells in one:
In this galaxy, there is only one technologically advanced civilization - ours. We are unique.
Incredible. After all, there are billions of other planets that could harbor life. However, we must be careful, because the history of life on our planet shows that the transition from single-celled life forms to more complex, could not have been inevitable - quoted scientist newspaper Daily Mail.
His comments came in an episode of the film Human Universe production "Bi-bi-si." Second chance Cox calls fall to Earth meteorite that wiped out the dinosaurs race, allowing mammals and eventually dominate person on the planet.
We have all the forces trying to understand how it happened.
At the same time, scientists from Princeton University argue that people are not more likely to find alien animals and plants. They are advised to look for exoplanets traces of chlorophyll, which helps plants to convert sunlight into energy. According to them, this can be done with the help of the future telescope NASA to study habitable exoplanets.
Astrophysicists say that people have a chance to find a trace of water, oxygen and chlorophyll on an alien planet. According to NASA, our galaxy contains about a hundred million worlds, which can potentially be life. The agency hopes to find extraterrestrial life in the next 20 years. Chances are that the alien life form is found outside the solar system.
