Dennis Venema sought to persuade his fellow Christians that genetic science had disproven the traditional idea of a “bottleneck” of two human ancestors.
The changes involved in adapting a generic mammalian template into a whale are certainly not all simple, independent, single-letter changes.
A bottleneck of two, or a first pair at our origin older than 500,000 years, is possible.
Once upon a time, a cell became a tumor. Animals were soon to follow.
Recently Dennis Venema joined with Scot McKnight to publish a book, Adam and the Genome, in which they claim that there never was an original pair of humans like Adam and Eve.
