Goodness, something new here. This last image is new; at last you have come up with what you seem to be implying is a male australopithecus skull, which can be compared with the one I posted earlier, not caring whether it was male or female. I say “seem to be implying” because your images were all untitled and undiscussed.
I would like to add that if all your sneering and that by Cito and Fenrir, were about my ignorance of the difference between male and female australopithecus skulls, and if these lower skulls are indeed of male and females of that genus, then your sneering was misplaced.
Also, I think it might well be true that as you say, you have spent most of your adult life teaching evolution to undergraduates and that comparative primate morphology is your specific area of expertise. Also, that you are generally a sensible and intelligent person. But I also think that atheist ideology has messed up the human origin narrative you tell. It has stopped you from seeing what KIND of animal our deep ancestors were; in this instance by focussing attention onto intraspecific explanations amounting to a narrative of self-creation.
To rewind, we can now consider four skulls; gorilla and Australopithecus, male and female, supposing we are on the same page about that.

This is what I said earlier, and still think is true:
Seems to me that the striking differences between male and female gorilla skulls are due to the males being front-of-house for their family by offering protection against predators, whom they are prepared to fight to the death. The threat male gorillas present to predators is that of maiming by biting using their sharp canines and their powerful arms to tear our gouges and lumps of flesh. To get so close and effectively personal with predators who are themselves expert biters, requires a robust skull and sharp canines. By contrast, the females being protected from predation by the males, have less robust skulls. Their skulls look much more like Australopithecus (males and females) because Australopithecus also didn’t avoid predation by biting; they were fully adapted into using hand weapons for that purpose.
