Humans (and a lesser extent dogs) are too complex, mentally, to follow set behavoral patters based on race. Simply put, such patterns don't exist.
By what evidence do you state this? In order to say this, you must vigorously research the subject. However, vigorous research on racial patterns is taboo and avoided. I don't see how there exists such a large amount of research to say definitively "the pattern does not exist".
True but we have alot of research of psycholoigcal behavior of humans. As a mixed group, presumably, with seemingly no negative effect on the results.
Tho I will admit that race would be a very hard variable to control as culture influences how we percieve race. So even if you had two children, one black one white, growing up in the exact same family environemnt, they'll have vastly different experiences with regards to the rest of the world: Media representation, schools, racist people, news, etc...
So I'd shudder to wonder how you could make any kind of research on the subject.
Wild animals, however, are another matter. Some domesticated one as well like cows or sheep. Very predictable and its easy to say that "Yes this is a cow and its dosile" because cows have been bred that way and nearly all cows are docile as a reault
How is a human that much more complex than an animal when such a vast majority of our DNA is shared between them?
Because it is.
A mouse and a human are very different both psychologically and physcially. As far as we know, a mouse can't form language or complex thought. It has no artistic capability. No desire to build a society, just operate on instinct.
