In celebration of Pride Week, today’s episode tackles the question of whether female sexual fluidity has evolutionary origins, based on a controversial article by Satoshi Kanazawa (link below). We recorded this outside, so you will hear sounds of actual nature –squirrels and birds– and the occasional airplane and siren… as well as Graham frequently banging the table for emphasis, which causes a weird warbling noise on the microphone. This episode is brought to you by Chekd and by our books.
