Considering any extant species to be "less evolved" displays a fundamental misunderstanding of evolution. Evolution doesn't move towards a greater goal. All extant species - whether flatworms or humans - are equally evolved.
You certainly can choose any arbitrary goal of "evaluating" evolution, but any conclusions you come to are meaningless, because the premise that you can evaluate evolution this way is based on the fundamental misunderstanding of evolution that it works towards a greater goal. This is not true. Hence, any conclusion you make is not true...
"I'm definitely less evolved towards the underground movement than mole rat."
is not meaningless. When I say it you know exactly what I mean.
> misunderstanding of evolution that it works towards a greater goal
I never said there's any greater intrinsic goal of evolution (except fitting specific niche). I said you may specify goals for the evolution and evaluate how far it got towards reaching that goal.
For example, we are not sufficiently evolved towards covid immunity however we are somewhat evolved towards black plague immunity when compared to people who lived in times before black plague.
