Wow Jesus wasn't unique after all!

Captive shark had 'virgin birth'
Bonnethead (SPL)
The bonnethead is a species in the hammerhead group
Female hammerhead sharks can reproduce without having sex, scientists confirm.

The evidence comes from a shark at Henry Doorly Zoo in Nebraska which gave birth to a pup in 2001 despite having had no contact with a male.

Genetic tests by a team from Belfast, Nebraska and Florida prove conclusively the young animal possessed no paternal DNA, Biology Letters journal reports.

The type of reproduction exhibited had been seen before in bony fish but never in cartilaginous fish such as sharks.

Parthenogenesis, as this type of reproduction is known, occurs when an egg cell is triggered to develop as an embryo without the addition of any genetic material from a male sperm cell.

See how parthenogenesis takes place

The puzzle over the hammerhead birth was reported widely in 2001, but it is only with the emergence of new DNA profiling techniques that scientists have now been able to show irrefutably what happened.

The investigation of the birth was conducted by the research team from Queen's University Belfast, Nova Southeastern University in Florida, and Henry Doorly Zoo itself.

The scientists say the discovery raises important issues about shark conservation.

In the wild, these animals have come under extreme pressure through overfishing and many species have experienced sharp declines.

If dwindling shark groups resort to parthenogenesis to reproduce because females have difficulty finding mates, this is likely to weaken populations still further, the researchers warn.

The reason is that asexual reproduction reduces genetic diversity and this makes it harder for organisms to adapt - to changed environmental conditions or the emergence of a new disease, for example.

With normal sex, the mixing of maternal and paternal DNA introduces genetic novelty which can give animals new traits that might be advantageous in their new circumstances.

Sex marks

Dr Paulo Prodohl, a co-author on the Biology Letters paper from Queen's School of Biological Sciences, said: "Vertebrates in general have evolved away from parthenogenesis to boost genetic diversity and enhance evolutionary potential.

"The concern for sharks is that not only could we be reducing their numbers but we could be making them less fit as well."

"Our findings will now have to be taken into consideration for any conservation management strategy, especially for overexploited species."

The birth of the hammerhead (of the bonnethead species, Sphyrna tiburo) at Henry Doorly was as tragic as it was puzzling.

The new pup was soon killed by a stingray before keepers could remove it from its tank.

At the time, some theorised that a male tiger shark kept at the zoo could have been the father - but the institution's three bonnethead females had none of the bite marks that are usually inflicted on their gender during shark sex.

Some even suggested that one of the females could have had sex in the wild and stored the sperm in her body - but the three-year period in captivity made this explanation highly unlikely.

The new tests on the dead pup's tissues now show the newborn's DNA only matched up with one of the females - and there was none of any male origin.

Although extremely rare in vertebrates, parthenogenesis (out of the Greek for "virgin birth") occurs in a number of lower animals. Insects such as bees and ants use it to produce their drones, for example.

Two things spring to mind. Number one, is this shark destined to be the saviour of all marine life? And secondly how long before the Pope makes it a Saint?

MMmmmmm... Sacrilicious...

coooooooooooooooolllllllllllllllllllllllllllllllll lllllllll

That's neat.

Jesus had a dad, but for people that put stamps on religion have to blow up into divine proportions, therefore his mom was a virgin. Oh yeah, Buddah came out of a Lotus flower, and you can have a lot more fun if you look at some of the b.s. added to religions. What kind of sales pitch would you give to the next religion? My religion had a bigger dick than your religion sounds like something that George Carlin may say.

Just think for your shark to be anything special he's gonna have to swim on land. :D

I see myself and male tiger sharks have something in common!



I bet that stingray that killed it was jewish ;)

Oh. I thought this was about Mithras.

A-Sexual reproduction produces a copy of the parent.

Its natural cloning, not uncommon in plants, micro organisms and miniscule sea creatures, but in big sharks!

Yes good points they all get so mixed up that God and his band of light would laugh if the human consequences of ignorance wern't so damaging.
Jeshua Ben Josephs mother Mary was a 'temple virgin' as were all other temple virgins, all also named Mary, She got with a master craftman of the order, Joseph ,out of the correct time and month they were ment to concieve during, so at to have the correct star system over their new born to contiunue the line as it had always gone on.
The Essenses used to eat mana ,the bread of life ,made from amongst other things virgin blood and live grain.
So we got The blessed Jeshua, born a loving kind Picean and so came the heart felt change from studying/obeying law to feeling real love.

The lotus leaf is a geometric pattern of one form of the basic creative force out of a certain area that the Buddah consiousness errupted from, not litterally a lotus leaf but definatley that same structure from in spirit.The same God that made color coded skins on people formed all other things to suit each race. It is us who seperates them into litteral thoughts and subjects trying to grasp them. (He who grasps, loses) Instead of flowing along and realizing there are more parts to the sum now than just the original form, from the formless, nameless One.
