   @cereal It is known that 'useless' genes are removed over many years. Men are just more optimised humans.

     @thatbrickster @cereal Then again, the X gene probably has more functions for the human body. The Y genes are optimised to focus on creating the male part as that is what changes us from female to male. It's not about superiority, we all have X in us.

     @sim @thatbrickster @cereal evolutionarily I believe it is just a broken x chromosome so there's probably not a lot of evolutionary justification for it

     @Moon @sim @cereal @thatbrickster Isn’t there some evidence it’s getting smaller and weaker as time goes on?

     X and Y are descendants of a homologous chromosome. We can piece together lots of neat possibilities of their evolution. They may disappear, may revert back to autosomes.
