What is Pheromones vs. Color Vision in Humans about?

Humans have lost the ability to detect pheromones due to the development of full color vision around 23 million years ago. The gene responsible for pheromone detection, TRP2, became inactive or a "pseudogene" around this same time period. The emergence of color vision allowed primates to select mates based on visible color cues like skin patches rather than invisible scent molecules. Today humans consider factors like personality and lifestyle, in addition to appearance, when choosing mates.
