Absolutely. So I'm an evolutionary psychologist by training. Actually, my degree says biopsychology, but I'm an evolutionary psychologist. It all comes down to sperm and eggs. All right. It always does. So men produce millions of sperm on a daily basis. Women have all they're born with all the eggs they'll ever use. They'll probably only ovulate. times in their lifetime.

So if you look at reproductive potential, men could father as many people as they could find reproductive partners. Women, you're only going to get pregnant once, right? So Men have a lot more chances for reproduction compared to women. Men have a higher sex drive compared to women worldwide.

I'm not saying you're going to meet a woman who's not the horniest person you've ever met in your lifetime. I'm not saying that. But on average, men have far greater sex drive than women do. And we in evolutionary psychology attribute that to underlying biological differences. Okay, so how does that play into serial murder?

Like, okay, so women with these very limited eggs, very limited reproductive opportunity in the ancestral environment, it would have benefited a female to pair with somebody who had a lot of resources, right? Because not now, right? We are women, hear us roar, but back in the ancestral environment, you...

females were far more slender and helpless and whatnot it would have been really reproductively advantage advantageous to pair with the alpha male who had a lot a lot of access to resources and territory so men seek sex women seek money worldwide women prefer people with resources what are the number one motives for female for for serial killers sorry about that one more time

What are the number one motives for serial murder? For men, it's sex. For women, it's money. That didn't surprise me at all. Absolutely not. And then there was another perspective that I had, and it takes a little bit more. You got to bear with me on this one. But my team and I came up with the hunter-gatherer hypothesis of serial murder.

And it's not the only explanation, trust me, but it could be a part of the explanation for serial murders in that it is thought that, anthropologically speaking, we evolved from societies where men did the hunting and... Men did the hunting and women did the gathering, right? And so what do we see? Male serial killers as hunters. They stalk victims, unfamiliar victims.

They write down their times of day and where they work and their friends and they follow them just like a hunter would hunt prey. And they keep trophies, right? Like a hunter does. Women, it's, you know, use this one a little bit more figuratively. They gather victims. They gather the people around them. They look around, who is around me? Let me kill them. And then they gather profits as well.
