“I found this paper fascinating in that it is the first I’ve read that tries to examine the genomic architecture of this important phenomenon. As the authors note, similar analyses have been conducted in the past, but they are often directed at specifically trying to find loci that cause incompatibility between populations in the context of speciation, rather than examining this complex phenomenon.”
The whole post is here. There’s also an excellent perspective piece by Zach Gompert that accompanies the Miller et al. paper, and both will very likely appear in issue 21.6 (mid March).
