Another Virgin Birth Raises Questions

By Michael Squires     Oct 14, 2008 in Science
Another incident of Virgin Births has scientists in Omaha and around the world focusing on irrefutable DNA evidence of the existence of Virgin Births.
Scientists have confirmed that another Virgin Birth has occurred in a Virginia Aquarium as well as one in a Nebraska Aquarium.
The phenomena, is described as an Asexual Reproduction, or a parthenogenesis.
The medical mystery began 16 months ago after the death of Tidbit, a blacktip shark that had lived for eight years at the Virginia Aquarium & Marine Science Centre in Virginia Beach. No male blacktip sharks were present during her eight years.
In May 2007, the 1.5-metre, 42.6-kilogram shark died after it was given a sedative before undergoing a yearly checkup.
The 25-centimetre shark pup was found during a necropsy, surprising aquarium officials. They initially thought the embryonic pup was either the product of a virgin birth or a cross between the blacktip and a male of another shark species - which has never been documented, Chapman said.
Tidbit's pup was nearly full term, and likely would have been quickly eaten by "really big sand tiger sharks'' that were in the tank, Chapman said in a telephone interview from Florida.
That is what happened to the tiny hammerhead pup in the Omaha case.
"By the time they could realise what they were looking at, something munched the baby,'' he said of aquarium workers. The remains of the pup were used for the DNA testing.
Virgin birth has been proven in some bony fish, amphibians, reptiles and birds, and has been suspected among sharks in the wild.
The theory of a Virgin Birth has for many years been the subject of much discussion.
National Geographic startled the world with a report of a Virgin Birth at a Detroit Aquarium in 2002.
