Tempo and pattern of avian brain size evolution
Relative brain sizes in birds can rival those of primates, but large-scale patterns and drivers of avian brain evolution remain elusive. Here, we explore the evolution of the fundamental brain-body scaling relationship across the origin and evolution of birds. Using a comprehensive dataset sampling> 2,000 modern birds, fossil birds, and...Ksepka, Daniel T ; Balanoff, Amy M ; Smith, N Adam ; Bever, Gabriel S ; Bhullar, Bhart-Anjan S …
