This blog was first posted at Nature Ecology & Evolution Community on 14 April 2018 Preliminary conclusions about the possibility of a short, sharp human bottleneck A few months ago I asked this community if modern genome science had tested an “Adam and Eve” hypothesis that the human lineage has passed through short, sharp bottleneck… Continue reading Adam and Eve: lessons learned
Here is the text of a comment I posted at The Skeptical Zone in response to comments by Joe Felsenstein, Steve Schaffner and John Harshman on my Nature Ecology and Evolution blog on human bottlenecks: Thank you all for interacting with my Nature Ecology and Evolution Community blog, and thanks to Vincent Torley for posting… Continue reading Responding to Felsenstein, Schaffner and Harshman at The Skeptical Zone
Does genomic evidence make it scientifically impossible that the human lineage could have ever passed through a population bottleneck of just two individuals? This is a question I am asked semi-frequently by religious friends. With my current understanding of the genetic evidence, I can’t state categorically that it’s impossible. In this view, I find I differ… Continue reading Adam and Eve: a tested hypothesis?
