In a video released last week by Texas Tech University, Chatterjee explains some of his recent findings on life’s origin and evolution. “The origin of life—this must be one of the oldest quests for scientists and philosophers,” Chatterjee states in the video. Chatterjee then explains that amino acids, sugar molecules, and phosphate are all basic building blocks of life, and that these molecules’ origins on earth have long puzzled scientists. However, he suggests, ancient meteorites may hold the key to the genesis of these important molecules. MORE
