Re: Dromaeosaur disease resistance
Polygyny among dromaeosaurs would be unlikely: a male would have too >high

So what do you suggest as the alternative? We could just as easily rule out
polyandry for similar-but-opposite reasons. Monogamy and polygynandy being
the only other alternatives. At this point, who knows?
And why would the two females share the same nest?

Thus, in the macroevolution of dinosaurs, the radiation of clades

My question to you now is, why do you think dinosaurs (or dromaeosaurids in
particular, it seems) had any higher a resistance to disease than extant
