Biologists believed that the human race is now in the stage of development unprecedented in the last 200 thousand years , as a result of climate change , although it is not correct to mind the stage of a gene mutation .
He says the French scientist Jean-Francois Buffet "It's the first time in history where climate change and the environment a key factor in the evolution of the human race forward on the process of natural selection ."
He adds: "It is not sophisticated in the sense that he talked about Darwin , it is a kind of reverse evolution ."
And Jean-Francois touches buffet in his book " How will we formed in the future " to changes in the human race in a number of areas for decades , and which are sometimes drastic changes .
The average height has increased at a rate of five centimeters in three decades , and the rate of obesity has doubled in 15 years , to infect 15 percent of the population .
This kind of change does not exclude any region in the world , as well as precocious puberty , which is spread in the world, " especially in females ," according to the French scientist .
French scientist says : " There is no doubt that there are genetic factors responsible for that , but not the only , pointing to other reasons , including the use of agricultural pesticides and antibiotics , which increases doubts about the responsibility for obesity.
Buffet says "There is a boom chemical " rights has launched today is responsible for the changes in the race .
These materials , which often cause confusion in the system of hormones in the human body , its effects spread over long periods of up to hundreds of years , can not currently be predicted all the results and Artdadadtha .
The medicine is currently working to find solutions to some of these phenomena , such as infertility , as it has been producing sperm cells from stem cells , and experimented with this technique in mice , and thus is expected to end this problem in the next few decades .
Buffet says , " even if the man is sterile , it would be the ability to have children , including women ."
Thanks to medical advances , the average human life , but life in good health is no longer within the reach of a lot of people , and that " preventive medicine " which is based on genetic elements to identify diseases that may affect humans, it does not seem able to change this reality.
Says Jean- Francois Foe "We were the only sex between creatures who knows he will die , but now we may know what will be the
reason . This is not necessarily a positive thing ."
