An Evolutionary Enigma

• 🧐 A new UK study suggests kissing dates back over 21 million years, with Neanderthals likely participating.
• ❓ Evolutionary biologist Dr. Matilda Brindle highlights that kissing lacks an obvious survival or reproductive benefit, making it an evolutionary mystery.
• 🦠 Despite being unhygienic and a means of disease transmission, its persistence suggests it's an evolved trait.
