This is another example of micro evolution because the evolution is always limited to the same family of species.
Okay, so now the distinction between micro and macro has moved from differences within species to differences within members of the same family. Fine. So, did God specially create the three of them by three separate acts of creation, or were they once the same species, and then only later became three distinct species that cannot produce fertile offspring cross-species?
