<div dir="ltr">Congratulations Keith! A fascinating read.<div><br></div><div>A few questions and thoughts occurred as a I read it, which perhaps you have given some thought to:</div><div><br></div><div>Regarding why Bonobos don't go to war, could predation be a factor? Are bonobos preyed upon to a degree that Chimpanzees are not?</div><div><br></div><div>Also, why is there no concept of war among dolphins (that I am aware of)? Is it because their normal mating strategy involves males leaving their pod to find another, rather than remaining with their group and their females? -- pods usually being so small that without leaving it, would have extreme levels of inbreeding, whereas human tribes could be much larger (though it was perhaps not uncommon for females or males to exchange between tribes).</div><div><br></div><div>A final question: could the degree of inter-relatedness make more war costly for one's genes (e.g. if I am a species that has undergone a population bottleneck, and there is little diversity in genes, then all the people I would go to war with would effectively be close relatives (genetically speaking))? So could the amount of genetic diversity in one's species determine the profitability of war?</div><div><div><br></div><div>Jason</div></div></div><br><div class="gmail_quote gmail_quote_container"><div dir="ltr" class="gmail_attr">On Wed, Aug 6, 2025 at 1:15 AM Keith Henson via extropy-chat <<a href="mailto:extropy-chat@lists.extropy.org">extropy-chat@lists.extropy.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">---------- Forwarded message ---------<br>From: <b class="gmail_sendername" dir="auto">Keith Henson</b> <span dir="auto"><<a href="mailto:hkeithhenson@gmail.com" target="_blank">hkeithhenson@gmail.com</a>></span><br>Date: Tue, Aug 5, 2025 at 10:04 PM<br>Subject: Fwd: Journal of Big History Vol. VIII, Issue 2, 2025<br></div> <br>It took over two years, but the article finally got published in a journal.<div dir="ltr"><div><br></div><div>The bit about bonobos is a new observation.
