Or competitive evolution in order to mask the calls of nearby animals. <br> <br>One thing that these behaviors have in common is that they are produced by groups of animals who are in communication with each other but who are acting on their own – like people. <br> <br>The results of the project were presented on Nov. 16 at the annual meeting of the American Acoustical Society in San Diego, California. <br> <br>For more information, please visit: <br>http://www.newswise.com/articles/view/508342/?sc=dwhp <br>http://www.exploration.vanderbilt.edu <br></font></td> </tr> </table> </td></tr> </table> <script type="text/javascript"></script> <script type="text/javascript" src="<http://pagead2.googlesyndication.com/pagead/show
