Nothing my eye, Something for sure
I think it's addressed indirectly. Establishing that one factor (e.g. random mutation) explains some aspect of observation implies that all other factors (e.g. Lamarckian "progression," the intervention of intelligent deities, the colour of the scientist's hat, etc.) is not playing a role in that aspect of observation.
I don't buy that conclusion. But I do see how Ockham's razor leads to that conclusion if you are a materialist already.
