So I’ve been meaning to read more about evolutionary theory for some time, because though I’ve been aware of it, I haven’t really understood the inner workings. The Selfish Gene had been recommended to me by my friend, if middling poker player, Ethan Fingerman (who will gladly talk about transposons, at length, but I digress). So I went out to the local Barnes & Noble to pick up said tome, only to find that all 6 copies that were “in the Store” could not be found. So instead I picked up The Blind Watchmaker. It was a really interesting read.
There are some rather more intriguing applications of evolutionary theory. I know that I’m not the first to discuss this, but what really struck me was the evolutionary nature of technology and economy. Science has its own form of mutation and natural selection. New hypothesis typically arise from people believing that they know more than the rest of us (acting as a form of mutation). Then others will test that hypothesis until they break it, or it becomes an accepted theory in the current body of belief (acting as a form of natural selection). The same can be said of innovation and the market. Individuals or corporations create innovations (mutations), and then the market decides whether those individuals or corporations will succeed (natural selection).
Let’s assume that we will have similar phenomena in technological evolution as we see in biological evolutions. What types of things might we expect to happen? Well, per Dawkins, there are some interesting trends that we would expect.
The first is that we should see forms of convergent evolution. Biologically this typically happens within two different regions of the world, where two species evolve to develop the same characteristics independently of each other. Dawkins here discusses a fascinating tidbit involving two unrelated types of fish that each evolved to use electromagnetic fields as a type of radar if you will in order to navigate muddy waters. This means that starting from different origins, we should expect to see technologies look more and more similar in order to serve a specific niche. Remind anyone of competing software with similar feature sets?
Another interesting phenomenon of biological evolution is that of the arms race; whereby two different species which compete with one another will each be favored on the basis outdo their competitor. In the end they reach a competitive stalemate, as each advance in one is met with an advance in the other. Once escalation begins, each side is encouraged to continue the escalation or run the risk of being extinct, and the same happens in business. In fact, Dawkins himself points out an example of the cigarette industry urging a ban on TV advertising. Only by colluding and preventing any of them from gaining a competitive advantage, could they all reap the benefits.
While I’m not trying to make the oft cited, but riduculous comparison between pharmaceutical manufacturers and cigarette manufacturers in terms of their products, I do find it interesting that the industry as a whole lobbied for direct to consumer advertising. It would seem that this too is an arms race, that no one company can back down from assuming that their drugs aren’t single source for their therapeutic class until economic concerns force them to curb their spending (which Dawkins also states occurs for animals as well, they can only spend so much on speed for example before some other important trait is neglected).

This is a great book. I’m glad that you found it. It’s more general than the selfish gene I think, although I must admit I haven’t read this one. I suppose that the one thing that you should take away from it (and it sound like you have) is that evolution is not at all a strictly biological phenomenon. Any system that exhibits variation that alters it’s ability to compete will “evolve”. As you point out, economics is a prime example, but look at poker. Variants like Nico are better able to compete than you or I, so the final table selects for the players with the strongest abilities. While black swans do figure in, on the whole, beneficial variant skills will be more “fit” and hence more successful. Which is why practicing and trying different variations will tend to improve your game as you sample more and more approaches.
One thing to keep in mind when your having intelligent discussions on biological evolution is that individuals DO NOT evolve. Evolution can only act on populations of many individuals that exhibit variation. From this population, the more fit variations are successful and out-compete those less fit for resources. A common mistake made by non-biologists is to say that an individual evolves. While their thoughts or behaviors may evolve, their biological make up does not change during their life time. It is exclusively their variant offspring that will exhibit differential fitness.
BTW, another example of convergent evolution that creationists tend to throw at Dawkins is the case of vertebrate vs squid or octopus eyes. Both have a remarkably similar (and complex) structure, but distinct evolutionary origins. While this is the case, it is certainly not a reason to evoke “intelligent design”. If the current structure of the eye is one of the most fit that can exist within the constraints of extant biological systems, then it is not surprising that evolution will select for it numerous times over the course of history.

Thanks for the points Scotty, I’ve been aware of Lemarckian theories, and that they were not accurate, and Dawkins illustrates quite well how this could not be (in that organisms pick up injuries throughout their life).
Thats an interesting analogy to the poker experience. I wonder to what degree empiricism plays a strong role, and to what degree cognitive biases, and theoretical creations play a part. I think its a more valid argument to poker strategies as a whole. Although I suppose strategies as represented by individuals using them, could be seen as a form of natural selection.

Nothing constructive to add. So here’s my non-constructive post: The Making of the Fittest is a book on evolutionary theory which includes some of the coolest fish in the sea. And by cool, I mean they live in the arctic and that they have no hemoglobin.
Wicked.
That said, I haven’t read the book, so can’t tell you how quality it is or isn’t.
