Genetics is especially bad, since newly-discovered genes are named based on their function, while genes that were discovered in the early days of genetics research were instead named based on what happens to the body when they don’t work, since we didn’t know enough about biology back then to determine what their exact function was. This leads to situations like how one of the prominent genes featured in eye development is called “Retina and Anterior Neural Fold Homeobox,” and another is called “Eyeless.”
