If you want to ask you, "Are you not human," people certainly scoff: "!.? Nonsense 100% human curse Ah you do it," according to the latest achievements of scientists, humans seem to really not 100% pure ...... especially
one from Cambridge University research team recently has experienced an alarming discovery: there are 145 humans should not exist "foreign gene", which was supposed to belong to bacteria, viruses and other microorganisms, but now they play their own special in humans effect.
Scientists refer to this phenomenon as "horizontal gene transfer." This phenomenon in bacteria and other simple eukaryotic cells are common, they can share the genetic information to resist antibiotics. People do not know is that gene transfer can be achieved even from lower organisms to higher organisms.
For this discovery, the team leader said: "This means that the tree of life is definitely not in the traditional sense, with the Tree of Life is strict division of the various branches of the fact that it is more like intricate Amazon jungle, the various branches intertwined. overlap. "
These genes exactly when and how to enter the human body has become a part of humanity, and scientists have not understood. It was also on the "horizontal gene transfer" questioned, they think this phenomenon should have a more reasonable explanation.
