Season 1
Origins of Two Sexes
This audio essay explores the origins of the two sexes: how they formed 1.2 billion years ago and why they are nearly universal across the plant and animal kingdoms. The information for this episode comes from peer-reviewed sources in evolutionary biology on the evolution of sex, anisogamy, and the two sexes.

On January 22, 2023, the Paradox Institute recorded a live Twitter space on how the complex genetic and hormonal mechanisms that produce males and females can result in disorders of sex development. After an introduction into the biology of sex development, five people who were born with these various disorders discuss their experiences in detail, shedding light onto the developmental consequences of the sex binary. Co-hosted by PTElephant and XOTurner45. Participants with DSDs (on Twitter): XOTurner45, KatieInBoston1, DunkedHobnobs, XyDmu, and FreyaLee5806.
