The Institute of Arctic and Alpine Research (INSTAAR) and Department of Ecology and Evolutionary Biology (EBIO) at the University of Colorado, Boulder, (CU Boulder) invite applications for a tenure ...

A new study confirms that dolphins and orcas have reached a "point of no return" in their evolution, making a return to land biologically impossible. Their specialized aquatic anatomy, developed over ...
