The Hafner Brothers 

The Hafner brothers (from left to right: Dave, John, and Mark).  The photo was taken by Fernando Cervantes at his home in Mexico City in March 2005.  We had just completed a very successful field-collecting trip on Mexico's major volcanoes.  The trip commemorated the 30-year anniversary of our first professional field-collecting trip with all 3 of us together (a trip to the Great Basin in March 1975).   

People are often curious when they learn of the presence of three brothers in biology, especially three brothers who are evolutionary biologists working primarily on mammals.  As a consequence, my brothers, Mark and Dave, and I often find ourselves fielding questions about our family background, our education, and our childhood experiences.  It's not appropriate here to delve into a lengthy biographical accounting of the Hafner brothers (perhaps I'll do that elsewhere), but I will provide a few brief details and the links to Mark's and Dave's websites.  

Mark S. Hafner is the oldest brother and he is Professor and Curator of Mammalogy at Louisiana State University .  David J. Hafner is the youngest of the three of us and he is Curator of Vertebrate Zoology, New Mexico Museum of Natural History.  We are very close in age (Mark's about 13 months older than me and Dave's about 18 months younger than me), we're native Californians, and we have always been very close personally and professionally.
