I think the skirmishers might actually be female Kig-Yar. Its already been stated the spines make for males, and so the Skirmishers would seem to me like the female of the species.

Also, the Brutes I think Bungie said were primates, which would make them very similar to humans, if not even compatible. . . do I go to far? Probably.
