Do any of these kinds transition/evolve into the another? Or do they stay in that kind?
Maybe an analogy will help:
Imagine that you were a black Irish American.
You would be African because your great great great great grandfather was born in Africa.
You would be Irish because your great grandfather was born in Ireland.
You would be American because your father was born in America.
So - you (as an individual) would always be African, Irish AND American.
In the same way an individual dog will always be a mammal, a canine AND a dog.
You are not able to change your heritage - e.g. you could not become a black
Dutch American.
And an individual dog could not change to being a fish instead of a mammal.
Over the generations, your great grandchildren
could change their nationality though: e.g. their parents could move to Canada.
But then they would be black Irish American Canadians.
They couldn't alter their heritage.
And if, over the generations, 'mammal canine dog' evolved sonar they would not become bats.
They would become 'mammal canine dog sonar'.
They couldn't alter their heritage.
