I This sentence is deeply questioned because according to Darwin's theory of evolution, the probability of such a situation is too small, the structure of the organism and the functions of the various parts is due to appear during the synthesis of DNA mutation and the mutation to adapt to it around The environment has been retained, that is, the so-called evolution.
If the mutations make the human brain has the capacity to fight it, but such a capacity is a fundamental human need, with the surrounding environment does not matter, As long as human beings with 3% is sufficient, and that 97% did not exist and the need to be retained.'s Tail as human beings, there is no need for the degradation.
The theory of evolution is in accordance with the conclusions, but it is possible theory of evolution itself Perfect!
God or open a joke!
