While many of the assumptions made by Darwinism certainly form a fine framework for the assertion that some forms are more advanced than others, whatever genus is involved, and even down to the species level, in and of itself the perception of being advanced vs being primitive may be the result of observation.
Any observation will be seen through a cultural lens, so there will be bias inherent in the observer.
That bias enabled the exploitation of populations and resources which were considered primitive at that time, and through the lens of Western Civilization, would be possibly seen thus today in many regards, not the least of which is the violent elimination of the very history of western civilization through primitive means, and the aim to eliminate western civilization itself.
If that's racist, so be it.
I find it ironic that those who rely on Marxist doctrine are so hell bent on eliminating the progenitor of the Theory of Evolution, when "Cultural Evolution" forms the basis for their core doctrine.
Of course, they see themselves as the advanced form.
