What I've been talking about

I’ve been talking about nearly nothing else since I recently heard about the Axial Twist Hypothesis, which posits that you and I and everything that has ever had a spine basically has its head on backwards. What this is is an attempt to explain why we’re internally asymmetrical, why our brains control opposite sides of our bodies, and also something called Yakovlevian torque. Admittedly, I just skimmed the part about zebrafish embryos and am somewhat unclear as to what evolutionary advantage the Axial Twist confers, but I acknowledge that its absence would make it extremely difficult to button one’s shirt.
