Yeah, it's true what. For that they take these female hammerhead shark? It all began in December 2001 in an aquarium at the Henry Doorly Zoo in Nebraska ... That day, staff are faced with a mystery equipped with tiny fins. Indeed, there in the aquarium is a baby shark. All riquiqui, cute. A beautiful birth, but leaves doubtful. For in this aquarium, there is definitely a mama shark, but there is no daddy shark. There, there, there are only females. So I hear you coming with your arguments hyper-rational, the explanation is simply that the female had made knock before his captivity. Nope, no way, or so it was a long pregnancy for females, they no longer faced a male partner for three years. Anyway I tell you a mystery. A mystery. Scientists have studied this phenomenon thus denying outright the divine intervention, the union against nature with a sea urchin or in vitro fertilization performed in secret by extraterrestrial descendants of survivors of Atlantis. They swept all this with the back of the hand, 'll understand why. Very down to earth, the scientists conducted DNA testing. And then, surprise, the mystery deepens ... There is no paternal DNA in the baby shark ... The conclusion of scientists is thus similar to a song by Jean-Jacques Goldman: "She made a baby all Only ".
Not possible? Yes! And the living proof is that baby shark catfish in the waters of the Henry Doorly Zoo's aquarium. Bother surprised, it is scientists ... Until then finds the director of the team that conducted the research "we all thought sharks reproduced only through sexual intercourse between a male and a female, "" we believe that the embryo of Madame shark was enriched by the small seed of Mr. shark to grow, as in mammals. " Well no! All that is history ... To the world its offspring, Madame can dispense sir. But where will we? Note that this trick has already been spotted from time to time in birds, reptiles and amphibians ... This horrible thing where we go from women, men, my dear Peter for their offspring is called parthenogenesis . A word barbarian that this morning, is not without worry, even m'affoler. What Will it serve us males if the representatives of the opposite sex begin to reproduce on its own? What will we serve? Not that parthenogenesis must banish, excommunicate him ... At the aphids and wasps, I do not care ... But if it starts to win the Sharks, the more it appears that laboratory, some scientists have managed to obtain parthenogenesis in a rabbit, a mammal like us ... I say "no" loners ... Not to rabbits, not the female hammerhead sharks emancipated ... I claim the right of men to continue to participate in populating the planet ...
