“Convergent Evolution Is Even More Improbable than Evolution Itself”

David Klinghoffer


From Jerusalem, Ira Berkowitz for ID the Future continues a fascinating conversation with Lee Spetner, author of Not by Chance and The Evolution Revolution. Discussions of what ails evolutionary theory hardly come more lucid or crisp than this.

What’s even more implausible than evolution? That would have to be convergent evolution, as Dr. Spetner, an MIT-trained physicist, points out. Darwinists pulled the concept out of thin air to describe how widely separated creatures on the phylogenetic tree independently “converge” on wondrous biological innovations, such as echolocation (in dolphins and bats, for example). That remarkable coincidence extends down to fine chemical details not found in other animals.

How did such things get there? If explaining the unguided evolution of echolocation in whales is tough enough, explaining how it popped up in bats, too, naturally multiplies the difficulty. In fact, Spetner says of convergent evolution that it explains nothing but is simply a case of “giving a name to our ignorance.”

As an alternative to Darwinian theory, Spetner proposes his Non-Random Evolutionary Hypothesis, evidently purposeful evolution as a response to environmental and other stresses.  He characterizes the idea neatly to Ira Berkowitz.
