How evolution has optimized the magnetic sensor in birds
https://phys.org/news/2024-04-evolution-optimized-magnetic-sensor-birds.htmlAdaptive #evolution and loss of a putative magnetoreceptor in #passerines: Corinna Langebrake et al. https://royalsocietypublishing.org/doi/10.1098/rspb.2023.2308
"there have been significant evolutionary changes in the gene for the protein #cryptochrome 4 and certain groups of #birds have lost it entirely. This is indicative of adaptation to varying environmental conditions and supports the theory that cryptochrome 4 functions as a sensor protein."
