Mankind is hopelessly stupid

Researchers claim intelligence of most people is reduced
The researchers argue that our intelligence is reduced because we do not need to survive. And these two processes - to think and survive - as it turned out, tightly linked.
After all, to find food, a place to stay but still simple enough to protect their farm and family from enemies, neighbors, our ancestors had to apply a remarkable ability to think. Today we are living comfortably, our refrigerators are always filled with food, we can eat all the time, and the scientific and technological progress has saved us from having to run naked through the jungle in pursuit of the tiger.
- Therefore, a person appeared gene mutations that are harmful to our intelligence - suggests the study's lead author, Dr. Gerald Crabtree of Stanford University.
Based on the calculations of the rate at which harmful mutations occur in the human genome, and the assumption that intelligence is involved in the development of two to five thousand genes, Dr. Crabtree suggests that over three thousand years and 120 generations we survived two or more mutations leading a deterioration of our intellectual and emotional faculties.
In addition, according to recent research results obtained by neuroscientists, it was found that genes involved in brain function, are extremely susceptible to mutations. According to Dr. Crabtree, there is no pressure of natural selection and a large number of susceptible to mutations of genes combine to gradually destroy our intelligence.
But how long will this process of "mental debilitation" last? It can not humanity that seeks to develop the macro-and micro - cosmos and nanotechnology - hopelessly grow stupid? Scientists claim: No, the process may stop. And by the time the decrease of intelligence threaten the technology, geneticists come up with what to replace natural selection, which will be considered old-fashioned way of evolution, writes Daily Mail.
For example, scientists can examine each of the millions of gene mutations that may jeopardize our intellectual development. And then there will be an opportunity to correct any mutation. And then the cruel process of natural selection itself will wither away as useless.
