Adherence to cancer, lupus, diabetes, predisposition to a long depression and even the inability to quit Smoking passed a modern man from Neanderthals, recognized scientists. According to their statement, if 80 thousand years ago the ancient portfeli people not interbred with Neanderthals, the earth's population would not have to fight with many dangerous diseases such as cancer. To such conclusion scientists from Harvard Medical school in Boston came after analyzing the distribution of Neanderthal genes in human DNA. Comparison results, published in the journal Nature, showed that genes Neanderthals are, as a rule, in those sections of DNA depends on the work of the male reproductive system, the creation of proteins of keratin and susceptibility to specific diseases. Creating keratins benefited ancient man, thanks to his skin, hair and nails become stronger, which allowed us to survive in a cold climate and fight some diseases. And the remaining genes Neanderthals had on him only negative effects. Specifically, in consequence of these genes of modern people is developing lupus, Crohn's disease (chronic inflammation of the gastrointestinal tract, liver cirrhosis and diabetes. Besides all this, they have great influence on the level of anti-inflammatory protein interleukin-18, which hinders the development of many infectious and autoimmune diseases, and in consequence of which almost all men suffer from long-term depression and can't quit. Also, research workers from the State history Museum in London are convinced that in the genes of Neanderthals and laid predisposition to cancer. The theory that the ancient people suffering from cancer, endorses the recent discovery of South American archaeologists during excavations in Croatia was found edge of the Neanderthal man, who died from bone tumors. It was found that the sample of about 120 thousand years hence, if you have a predisposition laid at the gene level and may not depend on carcinogens, polluting the environment, which during the time of the Neanderthals. This discovery, according to the researchers, may affect investigate the causes of the origin of oncological diseases and their prevention.
