GENDER ISN'T REAL

In a Biology classroom, we have an incredible opportunity to talk about gender and biological sex. There are tons of animals that have all kinds of amazing ways of expressing biological sex. For example, clownfish are one of many species that exhibit sequential hermaphroditism: they are born male and transition to female based on environmental conditions. In humans, "biological sex" exists on a spectrum! During fetal development, genital differentiation and sexual differentiation in the brain take place at different times under different environmental conditions. Not to mention the many intersex chromosomal conditions that can occur during gamete formation!

Check out this fascinating National Geographic article for information about human gender, and an article about sex-switching fish.
