This illustration was made for the book Our Genes: A Philosophical Introduction to Human Evolutionary Genomics that will be published by Cambridge University Press. It will be included in a chapter discussing the philosophical ramifications of the homologies between female and male genitalia. This illustration lines up the homologies during external genital development to show the clear correlation between females and males. It also goes into more detail than common developmental illustrations for this area, especially calling out the interesting relationship of the prepuces.
