Edriss in Visser describes some opinions on humans from a Yeerk perspective:
"He was unhappy about the war, unhappy about being seperated from his mate and progeny. And, at the same time, he was proud of doing his duty...The interest in progeny was persistent. It intruded on any number of thoughts. It formed part of the basis for the creature's sense of his place in the world.'
I would think interest in one's children would be a near universal trait among all species to survive, not really distinct enough to just be used to describe humans.
The experience of Edriss taking her first human controller is also described:
"This second half of the brain was an almost mirror image ... Not a fully redundant system, almost a second different brain!'
'Confusion! Disorder! Illogic! This mind could argue with itself'
No wonder they kill each other, I thought. They very nearly kill themselves!
In this respect, the diversity of humans and their lack of commonality among various human populations appears to be a defining characteristic in the ani-verse.
This holds if you look at the other species which do not appear to have comparable physiological variations that different human races do eg black Vs white people.
Although, Yeerks do explicitly distinguish themselves from other Yeerks when they meet by stating which pool they came from. However, such distinctions have not seemed too relevant in terms of their overall cooperation with each other, or general behaviour. Nor is it implied that certain pools have higher, lower or otherwise distinct status from other pools.
I suspect though that for any species, national, racial and individual self-identity broadens upon learning of other alien sentient beings. If we really did live amongst Yeerks and Andalites, I think the conflict in the middle east would probably be a largely non-affair, and the nuclear super powers would forget about pointing missiles at each other. We would be less likely to see racial/religious differences as a point of contrast, rather, humanity as a point of uniformity - distinct from non-human beings.
This would explain why various species in the Ani-verse such as Yeerks, Andalites, Skrit Na, etc are centrally governed and their culture and group characteristics are a lot more uniform.
I doubt though that we could effectively manage a wide-scale communal economy like the Yeerks and Andalites.
