Regular human

Somebody is considerated as human as long as his genetic alterations don't make him look like an animal more than an human.

The term is very large, so. Somebody without any genetic alteration is as human as somebody with a rat-tail, feathers or raven crows as long as it doesn't alterate his whole appareance.

Mostly everybody has at last one alteration but half of them are invisible, concerning their perception or their instincts.

The few unaltered humans are mostly from the moon or an isolated place where the oxygen would have been filtered since the no-return. In other words, it is very rare to meet one.
