Bergmann's rule (Ecogeographic rules 🌍)

Bergmann's rule is an ecogeographical rule that states that, within a broadly distributed taxonomic clade, populations and species of larger size are found in colder environments, while populations and species of […]

Dinosaurs break 200-year-old Bergmann's rule of zoology A new analysis of the fossil record shows that dinosaurs bucked an ecological trend known as Bergmann’s rule.

#Dinosaurs buck #BergmannsRule, a more than 170-year-old biological principle suggesting that species from colder environments are generally larger than close relatives from warmer climates. #biology cosmosmagazine.com/history/pala...
