What is race, in the anthropological sense?
Merriam-Webster dictionary defines The Human Race:
:all people :human beings as a group the history of the human race destructive weapons that could wipe out the (whole) human race
Can race be defined through analysis of DNA?
According to a Harvard University scientific report on race and origins,
…there is no evidence that the groups we commonly call “races” have distinct, unifying genetic identities. In fact, there is ample variation within races.
All the scientific papers I read on this subject uniformly say human beings are 99.9 percent identical genetically. African-American blood is fully compatible with a same-type blood of a blond-haired Swede or a black-haired Sioux Indian. Our organs are interchangeable. Between ethnic groups, the DNA molecule that defines the color and texture of our skin or eyes is identical, except for allenes, an infinitesimally tiny component of that gene.
So, the question of where the notion that one ethnic group is inferior to another must be answered and the answer can be found in a non-scientific theoretical book written by Charles Darwin titled:
The essence of Darwin’s theory, with respect to humanity, is there are superior races and inferior races. This idea spawned and published by Charles Darwin was an important element of support for the Nazi persecution of people groups whom the Nazis thought inferior: Slavs, Jews, Gypsies, mentally defectives, etc.
American slave owners used Darwin’s theory of the origin of the species to justify slavery.
So the question must be asked: how many races of mankind are there? The answer: there is only one race of men. Ethnic backgrounds do not a man define. It is the culture that defines a man.
Slavs, Jews, African-Americans, orientals, Europeans and Hispanics/Latinos are all one race. Period.
