The word "race" used to mean what "species" means today; however, since Victorians and earlier thought blacks & other races were different species, they used the word "race" to denote the different ethnicities & breeds - by the time the word "species" was created, "race" had come to mean the same as "breed".

It wouldn't represent a new species truly, unless you could invariably distinguish the organism from either of its ancestors in terms of behaviors, morphology, etc. By that criteria, we can represent blacks and whites as classes as being different species. You can analyze the charred remains of a corpse and use morphological factors to identify race. The research is there pertaining to average IQ differentials between white europeans and black africans, and the difference is substantial.
The hybridization you are describing is mongrelization. A general loss of distinguishing traits between the two parents. I'll tell you who's expense its at, but you already know.

Says domestication, the genetic changing so that animals are less violent can take place in 10 generations. They mention research that attributes domestication to fewer embryonic cells that form adrenal glans, which provide fight or flight response. The same cells form bone and cartilage, so as domestication occurs, the animals have weaker bones and floppy ears. It is also associated with looking more child-like appearance. They even touch on talking about differences in humans, that humans would domesticate themselves by living in communities where aggression would be punished and close bonds with friends would be more important than brute strength for survival/child rearing.

just because two species split doesnt mean there is a lot of genetical divergence. what has the most influence on genetics are the number of generations. for a meaningful change evolution has to go through many generations which are very long for humans compared to most animals so this means very long time spans measured in the hundred thousands. for changes that people think there are between human races much longer time spans would have been needed.
