This is neat

Apparently, there are two kinds of male dung beetles, the ones with big horns, and ones with no horns. How is this? Because while the horned males are fighting, the hornless males sneak into the burrows and sex up the females. And the hornless males have giant bug testicles. Bigger than the bug testicles of the males with giant horns.

This has interesting implications for worldbuilding. I talked some weeks ago about species with vast differences between the genders, but this brings to mind a neat thought: what if there were an alien species where males and females look very dissimilar, AND there are two different kinds of males.

(I wish I could remember the phrase that means "when there are extreme physical differences between the genders.")

That would be sexual dimorphism.

Where it gets truly interesting is when you apply it to genus Homo. Neanderthal males and females had less sexual dimorphism than humans have had since the earliest days of our evolutionary history. Where Homo erectus had the largest sexual dimorphism of any hominin save Australopithecus afarensis.

The implications of this may have something to do with why Neanderthals lived in bands of about eight while imagining what Homo erectus society would be like is more difficult. Because the implications of such diversity within the genus has a lot of problems for other aspects of politics for the Right and the Left.....

Figured the bit about sexual dimorphism in human evolution might be useful for your 'Verse as well. I feel it should also be noted that Australopithecus afarensis had males 50% larger than females, which exceeds that of modern *chimps*. So A. afarensis would have behaved more like gorillas than chimpanzees insofar as sexuality is concerned.

And to an extent as well you have Gorillas where males come in two categories: breeders, or really, really old ones with silver backs, and in the larger group blackbacks. The blackbacks serve as the police to a degree where the silverbacks are analogous to the leaders of a human group in those cases.

It's a pity Man knows more about the sexuality of Tyrannosarus rex than he does about that of Homo erectus, the last common ancestor between us & the archaics.

There is a significant difference between sex and gender. My favorite species from my novels, the Ah'Koi Bahnis, have one sex (hermaphroditic) and gender is basically just another part of their personality.

Ooh, a species that needs a whole other species to reproduce. Like flowers need bees and other insects, but with two animal species.

What's that about figs? Tell me.

LOL, a species of homosexuals! :-D

Hmm... I wonder if I should have some vocal minority in that culture that opposes heterosexuality (in this case referring to interspecies romances).

Not that anything could come from the interspecies romances, this isn't the Star Trek universe after all. But still...
