We have returned from a long hiatus to discuss a wonderful book entitled Bitch: On the Female of the Species by Lucy Cooke. Sarah asked James and Mark to read this book that gives an updated look at Darwin's original model of sexual selection, a topic we covered extensively in Season 4. In this episode we cover the introduction and first 2 chapters of the book. In our conversation about the book, we discuss how Darwin's stereotypical, and simplistic. views of male and female roles in mating and reproduction have persisted 150 years later. As Sarah says, we are still suffering from the hangover Darwin's misogyny. Chapter one of the book does a great job challenging the simplistic notion of what "is a female?", and we explore that topic in detail. Mark was enamored with the existence of gynandromorphs (gyn=female, andro=male, morph=form), organisms that exhibit both male and female phenotypic structures. This led us to discuss the difference between sex and gender and why the simplistic view, often exposed in popular culture of late, of there being only 2 sexes, is incorrect and ignores actual biology.  Image taken from https://www.eriebirdobservatory.org/ebo-blog/2021/2/21/a-second-bilateral-gynandromorph-northern-cardinal-in-northwest-pennsylvania We also discuss how stereotypical gender roles influence how biologists interpret the behaviors they observed which often leads to misunderstanding and faulty interpretations. We encourage our listeners to read along with us, as we plan to discuss Chapters 3 & 4 next episode.  Lucy Cooke (Photo: David Dunkerley) Here is another example of gynandromorphs, but in butterflies.Image from https://www.earth.com/news/gynandromorphs-half-male-half-female/ The opening theme to Discovering Darwin is "May" by Jared C.
