New paper out in Heredity: 'Evidence of long-term purging of mutation burden in killer whale genomes'. Time calibration of purging was through inclusion of an ancient (7.5Kyr) genome which was close to directly ancestral to the present-day population with signature of purging.

Narwhal narhwals because they are so awesome! Marie Louis @mariels.bsky.social shows recent but strong divergence in narwhal populations on different sides of Greenland maybe by learned migratory routes #ECSconference2025 🐋🦑🧪

First publication from @cherinebaumgartner.bsky.social in
@heredityjournal.bsky.social. Until recently North Atlantic herring stocks were thought to be genetically indistinguishable. This study shows similar gene flow among the killer whales that follow the Icelandic and Norwegian herring stocks.

Lukas Keller, @fieldgenomics.bsky.social and I asked 'What can genome sequence data reveal about population viability?'

Excited to share our new paper on mammoths: doi.org/10.1016/j.qe...! I was only involved near the end of this ~9 year project (science takes time sometimes 😅) with sampling being done in 2015 by Eline and Ashot, and Alba having done most of the heavy lifting, but happy to have contributed 😄 Thread 👇
