He thinks it’s still theoretically possible that the human race once passed through a short, sharp population bottleneck of just two individuals, followed by exponential population growth. Buggs disagrees with the assessment of Christian biologist Dennis Venema, professor of biology at Trinity Western University in Langley, British Columbia, who forthrightly declared in chapter 3 of his 2017 book Adam and the Genome that it is scientifically impossible that the human lineage ever passed through a bottleneck of two, and we can be as certain about this fact as we are about the truth of heliocentrism.
