As I said this is relative. It does not make sense to tell that one race of dogs is superior over others before you decide what do you want to do with a dog. If you want to hunt some races will be superior.
Relative? Races of dogs? We are talking about human beings. Science does not assert or imply one race is superior to another or that qualitative differences exist.
I like it. So you are telling me that science demonstrated that what applies to the animals or even to mammals does not apply to the human beings. I waited years to hear this! Please enlighten me, I would like some details.
