While many among our seven billion choose to bicker and argue about tiny differences between one fellow human being and another, the fact remains that we are the same species, and are, in fact, more like each other than anything else on this planet.

Scientists at the University of Washington have discovered that the relatively recent advent of new genetic variations has ripened humanity for evolutionary advances.
