I have no problem with your non breeding mice being a different species of mice.
But they are still mice.
I don't have a problem with there being many different species of land creatures.
I don't have a problem with there being many different species of water creatures.
I don't have a problem with there being many different species of flying creatures.
I don't have a problem with there being many different species of mankind.
I do have a problem when I am told anyone of those came from one of the others.
The problem arises because of the lack of evidence that everything has evolved from one living life form that began to exist all by itself.
sorry had forum problems the page would not load right
So you do not have a problem whit those mice becoming a different species of mice but you do have a problem whit all species comming from a single ancestor.
So if those mice would evolve further and grow hopping legs, a rabbit like tail and start eating bark would you still call them mice or something else.
if you look at the evidence so far you can see species changing their feeding habits, you have much evidence of species changing the lenght of their legs (lots of different dog breeds have diferent bone ratios in legs and ofcorse diferent lengts alltogether), and some humans get bourne whit a tail so it is logical to asume it is possible for some animal to be borne whitout one. So given the evidence it is possible that a mouse like the one above could evolve would you still call it a mouse or something else like a hoopelldoo.
And because it is no longer a mouse but a hoppelldoo do could you apply the same exsample to a pre human/ape like creature evolving in to a human.
Or is there something i have missed.
