A male guppy you totally want to bang because he looks like an orange fruit
Pleiotropy is the scientific term for when a single gene produces two unrelated effects. For example, male guppies like the one pictured above tend to be orange and have that spot on their tale—possibly because that color and pattern are sexually attractive to females, but mostly because they look like a piece of fruit. Props for the link to my girlfriend Lucretia, who can read and understand scientific articles much better than me. Nature has made wild male guppies orange not because it’s useful or sexy, but because breeding females mistake them for food. Today is Friday, and cause precedes motive in such a way that sense comes only after effect. Won’t you explore some terrifying coincidences with me?
