Paleontologists have resolved a decades-old debate over turtle evolution in a new study of 210-million-year-old skull fossils.

The relative importance of genetic drift versus selection to evolutionary change has long been debated. This debate has mainly focused over long-time-scales (e.g. hundreds of thousands of generations)...

Mammals display prominent diversity in the ability to regenerate damaged ear pinna, but the genetic changes underlying the failure of regeneration remain elusive. We performed comparative single-cell ...

Hallmarks of multicellular eukaryotic genome organization are chromosome territories, compartments, and loop-extrusion-mediated structures, including TADs. However, these are mainly observed in model organisms, and most eukaryotes remain unexplored. Using Hi-C in the silkworm Bombyx mori we discover a novel chromatin folding structure, compartment S, which is “secluded” from the rest of the chromosome. This compartment exhibits loop extrusion features and a unique genetic and epigenetic landscape, and it localizes towards the periphery of chromosome territories. While euchromatin and heterochromatin display preferential compartmental contacts, S domains are remarkably devoid of contacts with other regions, including with other S domains. Polymer simulations show that this contact pattern can only be explained by high loop-extrusion activity within compartment S, combined with low extrusion elsewhere through the genome. This unique, targeted extrusion represents a novel phenomenon and underscores how evolutionarily conserved mechanisms—compartmentalization and loop extrusion—can be repurposed to create new 3D genome architectures. ### Competing Interest Statement The authors have declared no competing interest.
