What is the main topic discussed in this episode?
Hello, everyone, and welcome to the Mindscape podcast. I'm your host, Sean Carroll. We talk a lot about complex systems here at Mindscape. And one of the interesting things to me about complex systems is there's a little bit of a tension between the fact that on the one hand, the space of possibilities is mind-bogglingly large, right? When you have a bunch of small constituents that can come together in different combinations, different patterns to make some kind of aggregate, which is a very typical thing that happens to get complexity. Generally, just the numerology works out that the number of possible aggregations or ways to aggregate things is ginormous. You cannot even possibly imagine that.
searching through all the possibilities and yet the tension is with the fact that in some environment if we're talking about a complex system that persists and adapts and flourishes and whatever that is somehow fitting into the environment where it exists there's kind of natural features that we see happening over and over again Power law distributions are just one famous example of this. But in specific complex systems like biology, in evolution, we see what is called convergence, right? You have different developments of sight, vision, and the eyeballs in different kinds of organisms may have developed in completely different ways, but end up looking very much the same. If we just thought about all the different ways you could arrange the molecules in the eyeballs, they would be just, again, unimaginably large.
How does evolutionary convergence manifest in different species?
But there's the right way to do it to actually achieve the purpose that you're trying to achieve. Both of these facts, the fact that the space of possibilities is ginormous and the fact that there is nevertheless sometimes convergence onto the best way to achieve some purpose or some goal or some adaptation, if you wanted to call it that, is very much alive in real-world biology today. And we can talk about that not only at the level of organs or different features of the physiology of an organism, but also culture, thinking, social organization, things like that. And these are exactly the issues we're going to be talking about today on the episode with Rachel Powell, who is a philosopher. who thinks about these things in a comprehensive and interdisciplinary way, bringing them all together.
How is there co-evolution between social traits and biological traits? Is there some sense of convergence onto different forms of social organizations? Are we a little bit overly anthropocentric? when we look at the ways that other kinds of species have decided to organize themselves. You know, we know a little bit about humans and we tend to view what other species have achieved and how they've organized themselves through that human lens. And as Rachel points out here and there in the conversation, all of this in addition to being very illuminating when it comes to life here on Earth, may even be relevant to thinking about other forms of life, whether not on Earth or completely artificial or something like that.
So I urge you to stick through to the end where we have some provocative thoughts on the future of humanity.
What role does contingency play in the evolutionary process?
You can't predict anything. That's one of the things about biology and society, etc. There's no absolutely firm, unimpeachable predictions. But one can speculate about this large space of possibilities. And in the case of the future of humanity, the space of possibilities is very large indeed. So let's go.
Rachel Powell, welcome to the Mindscape Podcast. Thank you for having me. I'm honored to be here. We're going to be talking, of course, about one big question in evolution, contingency versus, I don't know what to call it. I think you like to call it convergence, or people might call it predictability or whatever. Or necessity. Necessity, yeah, inevitability. Exactly.
How do social and biological traits co-evolve?
Before we get into all the fun details, why don't you give us your take on of the big picture state of the argument right now. I mean, as you might know, I have an evil twin biologist, Sean Carroll, who studies evolution.
