They genocided each other too.
The skeletal remains that we find of males at dig sites have vast amounts of damage to them, and we find significantly less women and girl skeletal remains. Aeons later and the heterogeneity of the Y chromosome is suspiciously low in contrast to that shown in mtDNA. That’s a lot of killing and raping

There was no mutation, or at least there’s no evidence for it. The big change 50.000 years ago likely happened because population density finally became large enough to meaningfully transmit and preserve culture.
