I dont want to throw another log on the 'Yautja/Hish' fire, but I cant help but throw another possibility idea out there.
Every main species seems to have subspecies involved as well. Take humans for example. We all walk on two legs, 2 eyes, nose, yada yada yada, but there are obvious differences in different cultures. IE- Caucasion, Africans, Asian, Hispanic, etcetera. Could it be possible that we could justify both of them by the subspecies idea?
Oh, PS, I have absolutely no intention of stiring up any racial things and was simply using examples to support my idea. Please dont get mad at me!
