The advantages of sex

A recent study (1) suggests that genetic interactions are driving selection. This is an important finding and it suggests that mutations are not sufficiently robust to propel populations to more dominant states. In fact, mutations may have a negative effect on optimal progression. It has major policy implications in that, if humanity were to survive, it would be largely driven by genetic interactions rather than optimization in sub-populations.
 
Humans seem to be on a dangerous course, propelled by an affinity to surface features and segmented utility. The leaders in most countries appear to be less intelligent than average and it implies suboptimal policies with long term deleterious effects. As they travelled out of Africa by foot, first to Australasia and then to China, they never imagined the state of affairs, they would find themselves in fifty thousand years later. Some travelled north and obliterated the gentle Neanderthals and some stayed put, only to be marginalized. Some crossed the ice bridge into the new continent only to be separated from the rest.
 
Without an abundance of genetic interactions, humans are doomed to oblivion. Fortunately, the idiots who run countries and corporations have a limited life span.
