In this week’s Medical Discovery News with UTMB’s David Niesel and Norbert Herzog: What do the New Mexico whiptail lizard, the water flea, the marbled crayfish, the boa constrictor and the bonnethead shark have in common? All these animals can create offspring without a fertilized egg. This means a diverse group of animals can produce young by “virgin births,” without sexual contact. This is not a new concept but we are now recognizing the wide diversity of species capable of virgin births. The news also appears in the Galveston County Daily News.
