Are old world vultures and new world vultures the same “kind”? Why did ornithologists classify one as being closer related to hawks than to the other vulture based upon morphological data? Why does molecular data confirm this observation?
God did not depend on the classification systems determined by man. It’s backward for scientists to say, “WE classified some things, and so God has to agree to our classifications.” God created before man could put a name on anything, and what man names something changes nothing in God’s order. God does not subject Himself to man’s classifications or wording. The fact remains that one kind of animal never becomes another kind of animal.
A lot of animals may look similar to our eyes and yet not be the same kind. And God was well able to make different kinds that still possess better than 90% identical DNA, and yet they are not the same kind. The creator’s definitions are ultimately what matters. Not man’s.
God was well able to make the tissues of one kind compatible for replacement parts in another kind, as He willed man to have the knowledge and skill to accomplish it in a surgical theater. It does not prove in the least that the one kind had ever been the other kind.
