Evidence of the first recorded romantic kiss dating back 4,500 years has been discovered

Records of the very first romantic kiss date back at least 4,500 years ago, new evidence suggests, about 1,000 years earlier than scientists previously thought. 
In a new article published in Science, researchers from the University of Copenhagen and the University of Oxford revealed their findings on the "ancient history of kissing" after drawing on clay tablets and other materials from early Mesopotamian societies. 
Ancient Mesopotamia is considered to be roughly the land that is now modern-day Iraq and Syria. 
It was previously believed the earliest evidence of romantic-sexual lip kissing in humans originated in South Asia 3,500 years ago. Then it spread to other regions, according to the University of Copenhagen.
