{"fact":"The genus *Corvus* shows the greatest variation in body size among Corvidae, with body size evolving at a faster rate, potentially as an adaptation to diverse climates and competitive pressures.","context":"Within these components, the genus Corvus exhibits the greatest level of morphological variation among Corvidae, particularly in LIN1 and LIN2. Body size (LIN1) is on average larger in Corvus than in other Corvidae and shows twice as much variation as the second most variable genus of the family (i.e. *Cyanocorax*)","source":"Joan Garcia-Porta; Daniel Sol; Matt Pennell; Ferran Sayol; Antigoni Kaliontzopoulou; Carlos A.
