Yes. In Darwin's opinion, those differences are unimportant, and were not independently evolved. The Human Genome project has verified his opinion; those differences are greater withing "races" than they are between them.There's one quote that almost sounds like he's aware of some equality, at least until we read the entire quote:
"Many of these are of so unimportant or of so singular a nature, that it is extremely improbable that they should have been independently acquired by aboriginally distinct species or races."
"The same remark holds good with equal or greater force with respect to the numerous points of mental similarity between the most distinct races of man." -Descent of Man
What Darwin saw as important is this:
The same remark holds good with equal or greater force with respect to the numerous points of mental similarity between the most distinct races of man. The American aborigines, Negroes and Europeans differ as much from each other in mind as any three races that can be named; yet I was incessantly struck, whilst living with the Fuegians on board the Beagle, with the many little traits of character, shewing how similar their minds were to ours; and so it was with a full-blooded negro with whom I happened once to be intimate
