Kissing Origins Traced Back 21 Million Years

A groundbreaking study reveals that the first kiss occurred millions of years ago, predating humans, and was likely shared among primates and Neanderthals. This research, published this week, explores the evolutionary history of kissing, a topic previously unexplored in evolutionary biology. The study defines kissing as a non-aggressive, oral-to-oral contact and uses genetic methods to trace its history, suggesting it evolved in most large apes and likely occurred in Neanderthals. The findings also indicate that kissing has a strong evolutionary link among Afro-Eurasian monkeys and apes, placing humans firmly within the broader animal kingdom. DNN | The Daily News Now!
