These acts provide proof that dolphins are compassionate., Within their social systems, they also form long-term cooperative partnerships and alliances, exhibit conformity (as is the case with the tool-using population), and learn from their pod members., Studies show that dolphins have special, spindle-shaped neurons called VonEconomo neurons, or VENs, that aid in the intuitive assessment of complex situations, like social interplay. document.addEventListener( 'DOMContentLoaded', function() { Comparative Cognition & Behavior Reviews, vol.
