So that’s where the penis comes from!

Well, the title pretty much says it all – two recent studies shed some light on the biological origin of the wiener.

Today, two teams of researchers report having solved one part of this mystery, pinpointing how the organ gets its start in snake, lizard, mouse, and chick embryos. Now that they understand the penis’s origin, researchers can track its development in more detail to understand what drives it to follow a different path in females and become a clitoris. The finding doesn’t just answer a biological conundrum; it could also help millions of people born with genital malformations.
