Definition: An &amp;quot;infinitary species&amp;quot; is a set X of organisms which is (i) infinite, (ii) ancestrally closed (contains every ancestor of every member of itself), and (iii) as small as possible with those two properties (i.e., no strict subset of X has properties i and ii). Theorem: In any infinitary species, every member is an ancestor of almost every other member (more precisely: of all but finitely many other members).…&lt;/p&gt;&lt;p&gt;&lt;a href="https://hackerpaper.kaipfister.de/p/1201.2869/"&gt;Paper and discussion history&lt;/a&gt;.

But the registration system should be way more open, you&amp;#x27;re discriminating against many math PhD&amp;#x27;s who are no longer in academia. I would have posted my paper there but I guess &amp;quot;@math.ohio-state.edu&amp;quot; isn&amp;#x27;t elite enough so I&amp;#x27;ll post it here and probably get more traction than all the papers on OP&amp;#x27;s entire site combined. https://arxiv.org/pdf/1201.2869.pdf &amp;quot;Infinite graphs in systematic biology, with an application to the species problem&amp;quot; (printed in Acta Biotheoretica).

This comment was made with the belief that you claimed that all infinite graphs have this property. Anyways, I know it’s an old thread, but if anyone is reading this, I highly recommend reading it.
