Honest question from a complete amateur here. I hope it’s pertinent. In your Evolution Basics posts on BioLogos that I read some years ago, I found the arguments from incomplete lineage sorting to be lucid, persuasive, and interesting. The very idea that there might be analogous genetic variation across different species, even through complete lineage sorting, was mindblowing to me (and intuitive, once I thought about it). Are we now saying that a bottleneck of two — even millions of years ago, shortly after the chimp-human split — can accommodate lineage sorting data without postulating these miraculous, so-called mosaic genomes?
Please forgive me if this is an elementary question covered elsewhere in this 892-comment thread. It would be wonderful if you could give me a link and say, “I already explained that here: [link].” Fwiw, I did a search for Incomplete Lineage Sorting and it only brought up a single snippet — the one above from Richard in post #12. Unfortunately, searching for “ILS” gives me dozens of posts with the word “detaILS” in it.
Thanks for any response you may have time to give. I suppose it would be great to hear from any of the other biologists on the thread, too, but I’m directing the question to Dennis because it’s something he’s written a good bit about and I’m confused why it no longer seems to be relevant to the bottleneck question.
