Reconsidering the evolution of brain, cognition, and behavior in birds and mammals
Despite decades of research, some of the most basic issues concerning the extraordinarily complex brains and behavior of birds and mammals, such as the factors responsible for the diversity of brain size and composition, are still unclear. This is partly due to a number of conceptual and methodological issues. Determining species and group differences in brain composition requires accounting fo...
متن کاملIntegrating brain, behavior, and phylogeny to understand the evolution of sensory systems in birds
The comparative anatomy of sensory systems has played a major role in developing theories and principles central to evolutionary neuroscience. This includes the central tenet of many comparative studies, the principle of proper mass, which states that the size of a neural structure reflects its processing capacity. The size of structures within the sensory system is not, however, the only salie...
متن کاملPreening and associated comfort behavior in birds.
The integument of birds has a considerably more complex structure than that of mammals. 1 In most avian species the plumage also has an important extra function compared with the pelage of mammals: flight. Accordingly preening, as a behavior that conditions the bird's integument, can be expected to play a more important role within the activity repertoire of birds than grooming does in that of ...
متن کاملTerritorial Behavior and Population Regulation in Birds
A close relationship between territorial behavior and population regulation in birds was claimed by Howard (1920) in his classic essay on territoriality and has been emphasized by both earlier and more recent authors (see Wynne-Edwards, 1962). At present, opinions on this matter vary considerably; but there seems to be widespread entertainment, and in some circles acceptance, of the idea that t...
متن کاملEvolution and Human Behavior
The large number and variable quality of recent research papers in the field of protein biosynthesis often has made it difficult for readers to discern clearly the experimental basis (or lack thereof) of the interpretation put on the results that are presented. A new series of volumes has been initiated, therefore, to provide critical discussions of the methods used in this active area of bioch...
