I think parent commenter meant among humans. From the very Wikipedia article you linked we also find: > In humans, the concept of an alpha male was challenged as being largely nonexistent per an article by Dean Burnett, who found that human leadership roles vary wildly based on the current social context, and traits attributed to an "Alpha" might be exhibited in one scenario, and traits attributed to a "Beta" might be exhibited in a different scenario by the same individual. Also from the same article, since wolves are often used as an example when talking about alphas: > Researcher L. David Mech, one of the primary creators of the Alpha male hypothesis for wolves, later found additional evidence that the concept of an Alpha male may have been an erroneous interpretation of incomplete data and formally disavowed this terminology in 1999. He explained that it was heavily based on the behavior of captive packs consisting of unrelated individuals, an error reflecting the once prevailing view that wild pack formation occurred in winter among independent gray wolves. Later research on wild gray wolves revealed that the pack is usually a family consisting of a breeding pair and its offspring of the previous 1–3 years. Whereas among chimps and gorillas for example we do find alpha males like the article says, but I don’t think anyone was contesting that.
