Again, evolution is not goal driven.
Animals have A or B, but AB is not evolutionary advantageous to survive. This is not goal, it is a simple statement of what exists. The explanation is that A moves to B along an evolutionary line, where none of the AB survive long term. This is a result, not a goal. Further evidenced by lack of any animals that progressed from B back to A (result, not goal).
As I said, A has advantages, B has advantages, but AB appears to have neither, due to lack of any remaining AB hybrids. A mutates and starts progressing towards B, it either stops and reverts at some point, staying A or it continues to B. However, the AB stage is temporary, thus indicating long term viability of AB is limited if it exists at all.
Again, you keep insisting goal driven results of advantages.
Do you understand the difference between goal and result? Goals require intelligence, results simply exists. Advantages lead to certain results. Disadvantages lead to different results, but results none the less. Evolution is all about results of traits towards viability. Viability is the "goal" ;) In my sentance, I clearly show that A progress towards B in such a way that AB doesn't remain behind. That is a result, not a goal. The viability of AB is what I am questioning, since there is no such thing long term. Viability of half stages is in question.
The Term Superiority is one of resultant progression. As far as I know, B never revered back to A.
Dogs and wolves are both Canines, and not enough differences exist to support your hypothesis. I've seen tamed wolves and wild dogs, to the point where the wild dogs were more dangerous to humans than tamed wolves. ;)
