Speciation is the scientific theory attempting to identify the biological mechanisms by which a single ancestral species of organism differentiates, or "evolves", into more than one descendant species. The term "macro evolution" is often substituted inappropriately for speciation theory, creating the false impression that speciation is nothing more than a logical extrapolation of Darwin's theory of natural selection. But it isn't. As I wrote in my book Counterargument for God, either two members of the same ancestor species eventually spawn offspring of a new species, or members of two different species produce a fertile hybrid species. There doesn't really seem to be a viable third alternative, at least not one that doesn't involve creation by some form of supernatural intelligence. In an effort to clarify my understanding of how speciation theory supposedly worked, I wrote an open letter to biologist Dr. Jerry Coyne, author of the book Why Evolution is True. Apparently, Dr. Coyne couldn't find time to respond. However, his fellow biologist, Dr. Benoit LeBlanc, was kind enough to answer my questions. Dr. LeBlanc confirmed that my "basic understanding of the [speciation] process was sound", but suggested the reason my conclusions were all wrong because I simply don't know enough about biology. No offense intended, he said. None taken, Dr. LeBlanc. But I am still confused. In my analysis of Dr. Coyne's work previously deemed sound, I noted he speculated that speciation only seemed possible when a small breeding population comprised of members of a … [Read more...]
