This one has….evolved

[u/_who-the-fuck-knows_ → u/Away-Wave-2044]

This is kinda how evolution works. Random mutations in genes. The good mutations carry on through breeding.

Nah it's the opposite really. As long as the mutation doesn't cause your death then it'll survive, even if it's just a gene that does nothing useful. It may even be useful before reproduction but detrimental afterwards and still may be passed down to the next generation through the breeding process

It doesn't have to cause your death, just make you less successful at reproducing. Even a small reduction in success will be bred out over time.
