On islands, palaeogeography can influence a species' evolution, as seen here in the Aegean darkling beetle. The formation of the Mid-Aegean trench & the Messinian salinity crisis coincided with speciation events in Dailognatha, resulting in hybridisation, introgression & ILS! 🧪👇

Mito-nuclear discordance in a genus of darkling beetles (Coleoptera: Tenebrionidae: Dailognatha) reveals both incomplete lineage sorting and introgression driven by complex island palaeogeography

and a quick note, the calculation about negative selection abruptly dropping neanderthal ancestry in humans in ~10 generations is not mine, it's from one of the best (and IMO underrated) articles of all time on the topic by Petr et al in 2019:

Similar in size and traits to today's Shiba, they formed a distinct genetic lineage. Remarkably, about 9.5% of their genome came from the Japanese wolf, a unique introgression that helped shape modern native Japanese breeds, which still retain 45-52% Jōmon ancestry.

Yeah, junctions (and ancestryHMM as well I think) both assume that geneflow stops after hybridization, e.g. the hybrid population is fully isolated from the parents. To obtain non-discrete estimates or values < 2 you need to include ongoing introgression, which is hard. Great work!

For some loci, the most divergent allele still circulating will be Denisovan, for some it will be Neanderthal, and for some few loci there’s been no introgression and the deepest branches are somewhere in Africa.

これは別に大して難しくないケースで、ハイブリッドを完璧に形成できずにintrogression があるのなら、ハイブリッド形成不全に分子生物学的実体がある時点でそれは別種。遺伝的に完璧に分かれた系統間でもintrogression はよく見られるが、それは分子機構が違う。したがってそれは分類学的なセンスの方に問題がある。

Loss of diversity implies introgression is occurring, as well as a rapid loss of genetic diversity - otherwise known as genetic erosion. Add in the predators, and you have a recipe for disaster without conservation. That stinks.

Neg selection was 2-3× stronger on chrX than on the autosomes. However, as seen in many systems, adaptive introgression occurs. In simulans-majority populations, sechellia ancestry on chr4 and 2 loci on 3R initially declined, but reversed after 10 generations, in contrast to the rest of the genome
