Rewind to 200,000 years ago—humanity’s dawn in the African savanna. In a world of predators and scarcity, survival hinged on sight. Women, often the gatherers, scoured the earth for ripe fruits, edible roots, life-giving plants. A 2007 study in Current Biology revealed a clue: women may have evolved a slight edge in color discrimination, especially reds and greens. Why? To spot crimson berries against emerald leaves, to discern poison from nourishment. The X chromosome, doubled in women, carried the key—genes for cone cells, the retina’s color sensors. Some women, maybe 12%, hold a mutation: a fourth cone type, a whisper of tetrachromacy, seeing shades invisible to most. In the crucible of survival, their eyes became silent weapons, shaping humanity’s pantry. But was this advantage myth or truth?
