The virus will evolve toward benignity, but only IF the transmission rate is slowed. If allowed full freedom, the virus will first evolve toward virility (high mortality rate) and then, as herd immunity is achieved, become mild and endemic. Think of the competition within each host between the different strains. The benign strain is making fewer copies of itself, but has a greater chance of being passed between hosts; the virulent strain is making more copies, but in that effort, is killing off it’s hosts quicker. It’s a trait group selection problem. Under high transmissibility, the virulent strain wins; under low transmissibility, the benign strain wins. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I hope I got that right. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Nick <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Nick <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><div><p class=MsoNormal>Nicholas Thompson<o:p></o:p></p><p class=MsoNormal>Emeritus Professor of Ethology and Psychology<o:p></o:p></p><p class=MsoNormal>Clark University<o:p></o:p></p><p class=MsoNormal><a href="mailto:ThompNickSon2@gmail.com"><span style='color:#0563C1'>ThompNickSon2@gmail.com</span></a><o:p></o:p></p><p class=MsoNormal><a href="https://wordpress.clarku.edu/nthompson/"><span style='color:#0563C1'>https://wordpress.clarku.edu/nthompson/</span></a><o:p></o:p></p><p class=MsoNormal> <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p></div><p class=MsoNormal><o:p> </o:p></p><div><div style='border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b>From:</b> Friam <friam-bounces@redfish.com> <b>On Behalf Of </b>Prof David West<br><b>Sent:</b> Tuesday, May 26, 2020 1:57 PM<br><b>To:</b> friam@redfish.com<br><b>Subject:</b> Re: [FRIAM] Covid and Politics<o:p></o:p></p></div></div><p class=MsoNormal><o:p> </o:p></p><div><p class=MsoNormal><span style='font-family:"Arial",sans-serif'>Does not Ewald suggest that a virus might evolve to be more benign vis-a-vis its hosts so as to maximize the number of potential hosts, i.e. avoid killing them off and reducing their will and actions in resistance?<o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-family:"Arial",sans-serif'><o:p> </o:p></span></p></div><div><p class=MsoNormal><span style='font-family:"Arial",sans-serif'>Probably totally misread him as that is not at all my field of interest.<o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-family:"Arial",sans-serif'><o:p> </o:p></span></p></div><div><p class=MsoNormal><span style='font-family:"Arial",sans-serif'>davew<o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-family:"Arial",sans-serif'><o:p> </o:p></span></p></div><div><p class=MsoNormal><span style='font-family:"Arial",sans-serif'><o:p> </o:p></span></p></div><div><p class=MsoNormal>On Tue, May 26, 2020, at 1:49 PM, <a href="mailto:thompnickson2@gmail.com">thompnickson2@gmail.com</a> wrote:<o:p></o:p></p></div><blockquote style='margin-top:5.0pt;margin-bottom:5.0pt' id=qt><div><p class=qt-msonormal1>It gets even MORE interesting if we consider the variable environment to which the virus is optimizing.
