Darwinism Falsified in Science Long Ago?

I’m pretty sure that is NEGATIVE selection coupled with recombination. Of note, this doesn’t explain how to make sense of how Y chromosomes evade Mullers rachet. A recent study solved this. Y Chromosomes are protected by large duplications and self-gene conversion events, plus negative selection. Effectively each Y chromosome is highly redundant and self-recombining. Pretty cool, right?
