Some random, incendiary thoughts
From my point of view:
-alphas and gammas have higher intelligence, IQs or whatever than betas and deltas.
-big IQ differences (above 30 points) make it impossible to communicate, even when it comes to small talk
-alphas and gammas care more about health than betas and deltas, which are usually into drugs
-without communication, groups isolate
-betas and deltas are physically stronger than alphas and gammas and do more physical activities
-betas and deltas, due to their aristocratic prejudices, don't socialize as much as democrats and this decreases even more their IQ
-alphas and gammas could evolve into the first "slim, beautiful, cerebral" group and betas and deltas into the second "tough, physical" group
