Many later nations have non-human themes to differentiate from the earlier nations, which were dominantly humans and humanlike giants. Monkeys, Yomon-Jomi nations, Agartha, animal-headed Fomorians are all new in Dom3. I think one of the reasons is that the human nations needed many new eras, and doing humans all the time was boring, so the new nations were chosen from ideas that would be fun to make - that is, not humans. That'd explain why we only got Eriu and Tir na Nog in a patch even though the theme was in Dom2, and why new nations have so many summons, most of them inhuman.
