Sir, respectfully; The whole point of the 'living fossil' issue is that there is no evolutionary change in any organisms into another kind of organism and there are NO transitional forms. The one cannot be separated from the other for that is the very point I am attempting to make here.
So the real point of your posts here is NOT that animals maintaining similar forms over a long time period is a problem for evolutionary biology? What you have been meaning to say is that they are evidence that NO forms of plants or animals change over long periods of time?
That appears to be a very different point than you started with.
It is so different in fact that a new thread would be appropriate.
