What kind of argument is that for evolution? No first of any species? Then why all the hoopla involved with the Endangered Species Act? You would think that all the "best science" scientists would me raving at Congress that there is no such thing as species. If there is not a first then there is not a last. Go figure.
It's not an argument for anything. It's a statement of fact. There is not firs of any species. Not nonow. Not ever. You should try understanding biology before you think you have the wits to trash it.
