No, jaguars did not have glow-in-the-dark eyes before they evolved. Their eyes possess a layer called the tapetum lucidum, which reflects light and enhances night vision, giving them a luminous appearance in low light. This adaptation is common in many nocturnal animals but does not equate to the ability to glow in the dark. Evolution favored traits that improve survival and predation, which includes their keen eyesight.
