Merry Christmas you parthenogenic animals!This week we have birthed you a very topical episode all about the most festive thing you can imagine: virgin births!This week Ron and Laura explore the concept of parthenogenesis and have a look at some ways of procreating that are non-typical compared to most species on the planet.We wish you a very merry Christmas - what better way to get in the spirit than with some weird lizard babies and a shark that runs a library and how could we possibly let you enter Christmas week without dragging poor old Matthew McConaughey back into the fray.
