Scientists discover ‘skinny’ gene
Certain flies, mice and people are just born lucky (except in time of famine

Graff and his colleagues wondered how good copies of the gene would impact survival in the wild. So they subjected the skinny flies to famine-like conditions. Not surprisingly, they did poorly. From an evolutionary perspective, this gene is the one that helps animals do well in affluenttimes — very much like the situation in western countries today, says Graff.
In times of plenty, these super skinny, sleek and fast flies can easily get away from predators,” Graff adds. “But in times of shortage, they don’tmake it.”
Many native land peoples survived hundreds of years of famine cycles, thus those who carried these shinny genes dead out, where as
those who had the efficient genes lived to reproduce. The European affluent diet is therefore a much greater issue for these people
