Science shapes every part of our lives, but so much of its influence is overlooked or buried in the past. Tiny Matters is an award-winning podcast about tiny things — from molecules to microbes — that have a big and often surprising impact on society. From deadly diseases to forensic toxicology to the search for extraterrestrial life, hosts and former scientists Sam Jones and Deboki Chakravarti embrace the awe and messiness of science and its place in history and today, and how it could impact our world’s future. New episodes every Wednesday. Tiny Matters is brought to you by the American Chemical Society, a non-profit scientific organization based in Washington, D.C., and is produced by Multitude.
In 1893, Belgian paleontologist Louis Dollo suggested that evolution can’t go backwards in the exact same way that it proceeded. This became known as “Dollo’s Law,” and came under a lot of scrutiny. But, more recently, Dollo’s Law was co-opted into the idea that traits, once they gain a certain amount of complexity, can’t return to a simpler state. In this episode of Tiny Matters, we explore two exciting examples where scientists have found that not to be the case.
