The "zombies" genes of the elephant against cancer

A huge elephant does not always have a huge defensesays an African proverb. The study of Professor Vincent Lynch and his colleagues at the University of Chicago, published in "Cell Reports," have just proven the opposite – at least in the case of cancer. In the seventies, the epidemiologist Richard Peto was already watching, but he can not explain it scientifically. Theoretically, the longer an organism lives and is longer, the more likely it is that one of its many cells will mutate and degenerate into cancer. In theory only, because a paradox that the & # 39; paradox of Peto & # 39; is named, according to his inventor, shows that the elephant, despite the insane amount of cells it has, is less likely to develop cancer (5%) than a smaller species … like man (25%).
