Since women have two X chromosomes, they could potentially carry two different versions of the gene, each encoding for a cone that is sensitive to slightly different parts of the spectrum. Females are better at discriminating among colors, researchers say, while males excel at tracking fast-moving objects and discerning detail from a distanceevolutionary adaptations possibly linked to our hunter-gatherer past.
