 I've also looked at the genetics and the morphology or the way that the sharks are shaped to understand how they're related to each other. Because there's kind of like two conflicting hypotheses about like how the hammerheads evolved. And one of those hypotheses actually suggests that the hammerhead head was actually like entirely an accident and they've actually been evolving it away this whole time. And we've been trying to figure out what it's useful for and the answer may be nothing.
