Bshary R Gingins S Vail AL 2014 Brain evolution has often been correlated with the cognitive demands of social life. Further progress depends on our ability to link cognitive processes to corresponding brain part sizes and structures, and, ultimately, to demonstrate causality. Recent research suggests that fishes are suitable to test general hypotheses about vertebrate social cognition and its evolution: brain structure and physiology are rather conserved among vertebrates, and fish are able to perform complex decisions in social context. Here, we outline the opportunities for experimentation and comparative studies using fish as model systems, as well as some current shortcomings in fish social cognition research. https://sonar.ch/global/documents/115496 eng info:eu-repo/semantics/altIdentifier/doi/10.1016/j.tics.2014.04.005 info:eu-repo/semantics/altIdentifier/pmid/24815200 Trends in cognitive sciences. - 2014 behavior brain ecological approach fish physiology social cognition Animals Biological Evolution Brain Cognition Decision Making Ecosystem Fishes Social Behavior Social cognition in fishes. http://purl.org/coar/resource_type/c_6501
