An interesting thing to research after this is to look at other species. In humans, men get fewer copies of genes (hence also more colourblindness). In some other species like - I think - birds, it’s the female who has fewer copies and who also displays more variation in traits. Regarding the winner-takes-all phenomenon, there’s an interesting workup of the idea in the book The Sovereign Individual. Basically, in every market, there’s usually a winner. Before, there were many local markets. Now, there’s one mammoth global one, or at least a few regional ones. Correspondingly, there are fewer winners, who now win on a global scale.
