ISEN-ASTC-L is a service of the Association of Science-Technology Centers Incorporated, a worldwide network of science museums and related institutions. ***************************************************************************** An interesting read that highlights the impact of social behavior on the evolutionary fitness of related species. In a sense, social behaviors that may originally evolve as individually beneficial, take on an evolutionary life of their own over time that dramatically influence the shape of life itself. This look at the genetic heritage of ants, bees, and mud daubing wasps (my favorite being the invasive European Paper Wasp, touched upon in earlier posts). Possibly sociality itself proved to be a major driver in speciation itself. http://nyti.ms/1apNc89 A recently published evolutionary tree of ants and their closest relatives may provide answers to how ants evolved and spread to most corners of the earth.
