This exact question is discussed in Matt Ridleys The Red Queen. He puts forward that it’s better for evolution in more unpredictable environments where variation becomes an advantage and vice versa for stable environments. It’s a great book I’d recommend it.
The main thesis of the book is that because every other member of the species is evolving through generations you have to evolve at some rate even to stay still relative to other beings
To clarify: the wiki article mentions sexual selection but not the existence of sexes. Richard’s question is “why don’t we have sexual selection without sexes”. Does the book talk about that?
