Exactly - so why are you claiming one thing evolves into another when you only see only breeds in a species mating and producing new breeds????? Those fox will always be foxes - even if they live for the next billion years without going extinct. The only way a new fox will come into the fossil record is when circumstances enable the breeding of one fox breed with another producing a new breed of fox, with no evolution through mutation of one into the other.
What about swans and geese? Clearly of the same species - just different breeds of the same species.
"
Swans are birds of the family Anatidae within the genus Cygnus. The swans' close relatives include the geese and ducks."
Geese, ducks and swans are merely different breeds of the same species, because you constantly label them incorrectly. Just as you incorrectly labeled all those finches of Darwin's that all interbreed. You know, those finches none of you want to discuss, even if they are supposed to be the prime example of evolution?
