Would it be ethically correct to clify all human races as subspecies?

Such as they do with animals and plants. Because if you look at a rabbit from the plains of the United States and a rabbit from the Canadian tundra they are virtually the same just different colors and physical features. Know for humans (I don't mean this in a racist, bigot and or offensive manner this is just biology) as it's obliviously known people of a certain "race" have bigger or smaller physical features. For example a "African-Male" when compared to a "White-Male" has a differently shaped lumbar vertebrae as it tends to be more curved for faster speed and heavy lifting; "African-Males" also have larger organs than "White-Males" as seen on the lip and, . Also "Asian-Males" when compared to "White-Males" tend to have a smaller or denser bone structure and differently shaped eyes. So basically we are doing a Long Report on human biology for my cl and well I was wondering if you agree with my "theory" that human "races" are entirely different in their own unique way.
