According to this primateologist on the Mindscape podcast, apes and chimps etc have:

* emotions
* empathy
* politics
* cooperation
* altruism
* homosexual behaviour
* gender behavior differences
* socialization into gender roles
* gender non-conformity
* ingroup/outgroup discrimination
* sense of justice/fairness

But they don't have:

* racism (outgroup is more like gang affiliation than skin colour or genetics)
* homophobia
* social punishment of gender non-conformity

So it seems that in fact being gay or queer or transsexual is perfectly natural but being homophobic or transphobic or racist is against the natural order of things.

Apes need a sense of fairness and sharing and equity in order to have cooperative behaviour. If one group or individual hoards, so the sharing stops, then equity fails and cooperation breaks down and society collapses.

Females helping each other against overly aggressive males can make monkey society calmer and less violent in general. Female cooperation seems key to the difference between aggressive chimpanzees and the loving bonoboo cuddle-puddles.

Bullies have worse outcomes because others won't cooperate with them. The Alpha-males are the popular apes who are kind and altruistic and so politically supported. The despot alphas are more likely to be deposed by the group.

Lessons for us all there.
