Why do some clades contain far more #species than others? By testing competing explanations across terrestrial #vertebrates, this study reveals that #biodiversity patterns are most often shaped by long-term productivity-driven equilibrium dynamics @PLOSBiology https://plos.io/4vuS10G

#Regeneration of fins and limbs relies on shared cellular playbook
Immune cells, blood and repair #genes act in concert across three regenerating #vertebrates
Team cut fins off #bichirs and tracked #gene activity at wound after one, three and seven days, which revealed types of cells present and activity. Team compared data to similar new and existing data about #axolotl, salamander that regrows limbs, and #zebrafish, a that can regrow tips of fins

#Eyes of the world's longest-living #vertebrate, the #GreenlandShark, show little #ageing
Greenland #shark (Somniosus microcephalus) can live for up to 400 years in the chilly North Atlantic and Arctic waters, making it one of the longest-living #vertebrates on Earth. And according to new research its seemingly undead eyes are fully functioning and barely deteriorate even after a century. Unravelling the shark's anti-ageing secrets could benefit human eye health.
