Posidonia Oceanica Wikimedia Commons

A patch of Posidonia oceanica, a species of seagrass native to the Mediterranean, has just gotten its DNA sequenced and its age determined--and as it turns out, some parts of this particular patch are up to 200,000 years old. That easily destroys the previous world record of the oldest living organism, a Tasmanian plant believed to be around 43,000 years old. Ha! A youngun!

Scientists from the University of Western Australia administered the study on the seagrass, which grows in massive clumps and is continuously growing new branches and expanding. Also known as Neptune Grass or Mediterranean tapeweed, the seagrass reproduces asexually by cloning, and spreads far and wide so that it can survive even if one particular area becomes depleted of natural resources.

This particular patch consists of some 40 undersea meadows stretching from Spain to Cyprus--over 2,000 miles long. Neptune Grass has also spread to the Caribbean, but it's still most common in the Mediterranean, even though rising sea temperatures and development may put the species's future in jeopardy.

i read that there are a species of tree that "clones" itself to guarantee survival of itself. what if i injected a serum of this into my veins? would i like for 200 000 years?

let's wait, in few months we're going to see the extracts of this plant selling on store's shells marketing them as eternal youth remedy.

@Contoria,

yes our great fore fathers(the annuaki) manipulated there own cells to prevent aging and dna decay. that are immortal and a 100 years for us is like second for them. they programed thier own bodies to "evolve" to prevent death. they can die but not so easily. i heard of a group of annuaki that decided to engineer there bodies to be "cyborgs" when they die that automatically upload there minds into another body. there skin is made of Super strong material that makes kevler look like tissue paper. i hope one day to mate with one. during mating, instead of conception, dna is made stronger and improved.

Its amazing how new or old organism are found!

I find nothing more hilariously revolting than one poorly educated grammarian slamming someone else for misspelling a word.

Jedi: "i read that there are a species of tree that "clones" itself to guarantee survival of itself." - That there are a species? How bout 'there is a species'....?

Or... Jedi: "yes our great fore fathers(the annuaki) manipulated there own cells to prevent aging and dna decay." - fore-fathers... hyphenated word. 'The Anunnaki'... please capitalize proper nouns, and spell them properly, lest ye feel their wrath...

Jedi: "... manipulated there own cells to prevent aging...." - manipulated their own cells... this particular mistake occurred several more times in that paragraph alone...

Before you correct others, please, make sure you're not a public dunce, lest others call you on it.

Have fun, kids!

(if I misspelled or misused a word or phrase in this comment, please, forgive me.)

If anyone should defend Jedi, you should Contoria... great attitude, much appreciated...

....however, I see folks doing that kind of thing far too often to not call attention to it occasionally.

I personally don't care about typos at all... unless they're by people seemingly making fun of other people for doing it.

Thanks again for being a good sport :D It's refreshing to see.

@shutterpod,

lol mr perfectionist, i was never correcting his spelling. when he said "kook" aid i thought he was talking and joking about a "kooko"(kooku for coco puffs) version of koolaid that makes one see things that are imaginary. if you had read the prior post you might have noticed it. but no you automatically assumed that i was getting on his spelling. spelling is the last thing i worry about. my post's prove that. i never have argued with contoria. we are cool.

From kook-aid, to kooko, from coco puffs.
The misunderstanding of this is just silly, lol!
I LOVE IT! ;)

Over the course of time say 100k to 200k years, I believe the enviroment, seas, temperature has change a lot. Of course that is my instinctive knee jerk thought. I am opptomistic that this grass will continue to thrive and do just fine. Perhaps the writer was trying to scare us with global warming. In this case, I do not believe global warming will have any doom effect on this grass. But hey, that is just me and 200k years is a very long time!

Plus, it could be that the grass is much older and adapted in the very old past as well, beyond 200k years.

Not really sure what they're saying here. Is this an organism that through constant growth is really the same organism? Or with the comment about asexual reproduction and patches are these clones of the original? Since there are varying ages for the patches, it sounds like it is clones, of which some lasted longer while others mutated upon reproduction more recently, and are "younger".
