I suggest that the hypothesized “Geneological Adam” does not represent a unique event in the evolution of the human species.
Rather, at any given time, approximately 18% of the human population consists of individuals who have been created de novo by a powerful supernatural being. Their genomes are such that they blend into and interbreed with the existing population without any genomic evidence that they did not originate from the same common ancestor as humans who were not created de novo.
The being responsible for their creation does not wish their existence to be known, so is very careful to ensure that no one is able to discern that these humans have been created.
One important consequence of this hypothesis is not scientific, but theological: 18% of the human population were not descended from Adam and Eve and so are not subject to “Original Sin.” This finding, if confirmed, would therefore provide scientific falsification for the Christian religion.
Can anyone provide scientific evidence that falsifies this hypothesis?
