This means that a kind of &quot;natural selection&quot; acts between the existing parts of a mixed state. Darwinism in the quantum world. <p>Interestingly, I have just come across a similar idea one or two weeks ago when reading &quot;<strong><a href="http://www.isbn.pl/I-0387984194/" target="_blank">Moral Calculations : Game Theory, Logic, and Human Frailty</a></strong>&quot; by Laszlo Mero. The author compares wave/particle dualism in physics, gene/group selection in biology, and other concepts from other fields with basic findings from game theory. So, is everything around  - nature, i.e. - just following a certain optimal strategy (which would be based on a probability distribution, as Mero shows) in a big game? The world just got a little bit stranger (to me, at least) ...<img src="http://c.services.spaces.live.com/CollectionWebService/c.gif?cid=4652575551799849501&page=RSS%3a+Quantum+Darwinism+(%3f)&referrer=" width="1px" height="1px" border="0" alt=""><img style="position:absolute" alt="" width="0px" height="0px" src="http://c.live.com/c.gif?NC=31263&amp;NA=1149&amp;PI=73329&amp;RF=&amp;DI=3919&amp;PS=85545&amp;TP=frankpr.spaces.live.com&amp;GT1=frankpr">http://frankpr.spaces.live.com/Blog/cns!409144D05FB2721D!127.entry#commenthttp://frankpr.spaces.live.com/Blog/cns!409144D05FB2721D!127.entryTue, 28 Dec 2004 21:36:43 GMT0blogentryblogentryBlog entryhttp://frankpr.spaces.live.com/blog/cns!409144D05FB2721D!127/comments/feed.rsshttp://frankpr.spaces.live.com/Blog/cns!409144D05FB2721D!127.entry#comment2004-12-28T21:36:43Z
