I made up a new word

"Adaptacious." It's a word for when you are trying to describe why some trait evolved. Kind of a mix of "advantageous" and "adaptive."

Example usage: Flashing lights capture our attention because it was adaptacious for early humans to notice sudden luminance changes in their visual environment, such as those when say a giant flaming meteor was coming down to kill their dinosaur buddies, or a burning bush was trying to tell them it was that it was.

I will fight you if you don't start using this word.

wait, maybe sad was always funny
