Our wolf paper is out! nature.com/articles/s4158… Analysing 72 ancient 🐺 genomes from the last 100,000 years, we: #1 chart wolf natural history through the Ice Age, #2 directly detect natural selection, #3 reveal that dogs have dual ancestry. A 🧵 (11), illustrations by @jessrpeto Wolf history: Throughout the Ice Age, wolf genomes cluster by time, not by geography—implying continuous homogenization of ancestry at a global scale. Genetic differentiation was remarkably low (FST < 3%)—an order of magnitude lower than today—demonstrating global connectivity.
