Cantabrian cornice has experienced 7 cooling and warming phases over past 41,000 years

The study analyzed fossil remains of small vertebrates in the El Mirón cave, revealing seven periods of cooling and warming in the region's climate. The findings suggest that forest-dwelling rodents flourished during warmer periods, while cold-adapted species survived and migrated to northern Europe.
