Yes, we know that is how you define it. Which is exactly why you are asked to explain ring species, because in such macro populations, your definition of "kind" fails.I'll stick with the 'if it can breed it is the same Kind' definition.
We've been over this....
Let's abstract it again to make ithe problem clear once more:
Population A, splits into two branches that creeps around a geographical barrier.
One side has populations A1, A2 and A3
The other side has populations Aa, Ab and Ac
At the end of the geographical barrier, A3 and Ac meet up again.
Now:
A can breed with A1 = same "kind"
A1 can breed with A2 = same "kind"
A2 can breed with A3 = same "kind"A can breed with Aa = same "kind"
Aa can breed with Ab = same "kind"
Ab can breed with Ac = same "kind"
So from this follows that in terms of "kind", A = A1 = A2 = A3 = Aa = Ab = Ac
So A3 and Ac are the same "kind".
But o-ow..... A3 and Ac can not interbreed!
See?
That's how that works.
And since we know that ring species develop as a result of evolutionary diversification of the "branches" that wrap around the barrier over time (call it "micro evolution" if that makes you feel more comfortable), this would mean that - giver your definition of "kind"- that ring species are the result of "evolution of one kind to another".
Whoepsie-daisy!
