Ya... humans have likely been doing this since our "cave-man" era days 140,000 years ago.

FOR EXAMPLE, here's a probable conversation of 2 Homo Sapien women, circa 100,000 BC:

"Did you see that Homo-Neanderthalensis chick from the cave near the beach, passed the reefs? She thinks she's all that just because she has more muscle mass and tons more stamina than you and I... but I'll tell you, she can barely string together a full sentence, and there ain't no way I'm lettin' her near my man anymore... muscles or not, a good Homo-Sapien-Advanced-Technological-Stone-Ax to her head will quickly clear up any misconceptions she may have."
