Phylogenetic history of social evolution and habitat use in the Aphelocoma jays
Article Abstract:
The historical transformation in social systems and habitat use of the Aphelocoma jays was examined using parsimony analysis based on an independent phylogenetic estimate. It was determined that social evolution has been phylogenetically conservative in these birds, with the beginning of cooperative breeding antedating the diversification of the genus and decrease in cooperation taking place posteriorly in two independent lineages. Changes inthe social system and habitat use seem to be correlated across phylogenetic history, but statistical importance of this correlation was hard to evaluate.
