It's been debated whether human groups have alphas in them or not. What's most likely true at least is if there are, the traits that would make someone one aren't universal. As an example, traits that make up an alpha male in middle school, could make them the bottom barrel in a hospital work setting. Or something like that, at least.
Although, I think most of the time when people are referring to alphas and betas nowadays, they're just using it as an insult.
