Think You Know Human Biology? XX / XY Isn't Even HALF the Story!
Human Development is complicated, but still not identity
What if everything you learned about human biology in high school was incomplete? Not exactly wrong, but breathtakingly oversimplified?
Science has known for decades that the XX / XY model of sex development is only a fraction of the story. Human genetics is complex: every human body carries instructions for far more than one outcome. The "switches" that drive which path gets taken are just biochemistry doing its job.
Politicians may pretend the science is simple. They're not even close.
Let's talk about:
☑️ Heritability: how we discovered the ability to pass traits from parent to child
☑️ Genetic Commonality: why you share about 90% of your genetics with your cat
☑️ Individual Complexity: why YOUR body developed the way it did
☑️ Making a Male: how human reproductive systems develop, and where politicians get it wrong
