A female blacktip shark at the Virginia Aquarium & Marione Science Center recently passed away, and, upon necropsy, was discovered to be with shark puppy -- despite no male sharks being present for 8 years!
Virgin birth has been proven in some bony fish, amphibians, reptiles and birds, and has been suspected among sharks in the wild. The scientists who studied the Virginia and Nebraska sharks said the newly formed pups acquired one set of chromosomes when the mother's chromosomes split during egg development, then united anew.
Absent the chromosomes present in the male sperm, the offspring of an asexual conception have reduced genetic diversity and, the scientists said, may be at a disadvantage for surviving in the wild. A pup, for instance, can be more susceptible to congenital disorders and diseases.
Proof positive that when a woman wants to get pregnant -- no matter how often you dunk your balls in hot coffee -- she's gonna do it.
Thanks to Heather and Abe, who both claim there was a dinosaur in Jurassic park that did the same thing. But they're wrong -- it was me!
