Assortative mating is essentially the recognition that theory isn\u2019t always perfect and that, however desperately biologists might want some simplicity in the world, organisms don\u2019t just encounter each other like gas molecules- it\u2019s not a random process. In fact, it can even give evolution a helping hand\u2026
