Paleogenomics Reveals a Loss of Bovine Lineages in Mid-latitude Asia Over the Last 200,000 Years Abstract. Bovines have a complex yet poorly understood evolutionary history that is characterized by admixture and diversity loss during the Late Pleistoce

@alexgilardet.bsky.social et al. recovered ancient DNA from bovine bones in the Denisova cave to characterize Pleistocene bovine diversity, identifying the Altai Mountains as a hotspot for bovine diversity.

💡A recent publication delves into the evolving concepts within microbial ecology.
Instead of focusing on new findings, the authors engage in a thoughtful discussion about the interplay between molecular tools and ecological theory in understanding the relationship between hosts and their microbes.🦠
