The mimic knocks into a dupe and gains in number, while the dupe declines. Without mimics, dupes grow in a standard way (exponential, logistic, whatever). Without dupes to exploit, a world full of mimics declines monotonically (exponential decay, or whatever).<br /><br />That gives you the boom-and-bust dynamics that generate cycles. The Lotka-Volterra equations are the simplest model of the general approach.agnostichttps://www.blogger.com/profile/12967177967469961883noreply@blogger.comtag:blogger.com,1999:blog-19346366.post-32994792835767513932013-09-10T16:45:13.388-04:002013-09-10T16:45:13.388-04:00"did you see the new thor movie?"

The funny part is, when i laugh or smile, he doesnt seem able to experience a genuine enough happiness or empathy to share the emotion. A smile seems to translate to a half sneer. <br /><br />P.S., agnostic, did you see the new thor movie?<br />http://www.artofvfx.com/THOR/THOR_WHISKYTREE_VFX_11.jpg<br /><br />The imagery could have used some blur, foreground, background, etc. the constant sharpness is so boring.

That's an equilibrium and we'd have stasis rather than cycles. That's the standard sort of explanation I'd read of frequency dependent selection. In order to get cycles we'd need something like inertia that keeps a shift going even as force builds against it.TGGPhttps://www.blogger.com/profile/11017651009634767649noreply@blogger.comtag:blogger.com,1999:blog-19346366.post-49092245607301943962013-09-09T22:58:10.775-04:002013-09-09T22:58:10.775-04:00I should have mentioned "red queen theory&quo...I should have mentioned "<a href="http://en.wikipedia.org/wiki/Red_Queen_hypothesis" rel="nofollow">red queen theory</a>" since my default mental model for predator/parasite-prey co-evolution.TGGPhttps://www.blogger.com/profile/11017651009634767649noreply@blogger.comtag:blogger.com,1999:blog-19346366.post-85643174619032302062013-09-09T22:56:41.045-04:002013-09-09T22:56:41.045-04:00Is there literature on cycles of mimicry in other ...Is there literature on cycles of mimicry in other species? I had also been under the impression that cuckoo mimicry was fairly stable. But since those are two different species, frequency dependent selection may not apply the same way.<br /><br />You've written about tattoos before, <a href="http://isteve.blogspot.com/2013/09/the-class-divide-did-you-have-tiger.html" rel="nofollow">Steve has data from Australia</a> on what kind of person gets them.TGGPhttps://www.blogger.com/profile/11017651009634767649noreply@blogger.com
