Seaweeds in the Mediterranean 200 thousand years old!!


Seaweeds in the Mediterranean 200 thousand years old!!

 Recently, Australian scientists have detects the genetic material of samples of seaweeds huge scientific name (Busadonaa Ohinnika Posidonia oceanica) located along the distance amounting to more than 3,200 km in the Mediterranean Sea between Spain west and Cyprus to the east and is likely to scientists that the age of these herbs are nearly200 thousand years and is thus the oldest living organism on earth.

These herbs that have been discovered recently lived much longer than its predecessor colony (Bando Pando) and located in the U.S. state of Utah, which scientists estimated age of 80 thousand years. (For more on this and other plants of the longest-lived organisms, Read: Tour of the longest and shortest ages organisms that live on the planet). Previous image to Bando colony.

Says the world (Carlos Duarte Carlos Duarte) from the University of Western Australia that the reason for offering these weeds in a lifetime back to being multiply manner asexual by reproducing itself as it produces new branches of large-size large numbers slowly storing food that they can continue to live inin bad conditions.

Scientists say this weed with a mass of more than 6000 tons threatened with extinction dramatically from several factors, the most important of drilling operations and construction taking place in addition to the coast in terms of global warming over the Earth's temperature forcing organisms to move to higher altitudes in the water inside to escapeof increased temperature at the bottom, but in the case of the Mediterranean basin, it becomes difficult because it is a closed basin as Europe is bordered to the north and from the south Asia, and also threatening the lives of these herbs also poor quality of water also caused by global warming.

Colonial receive daily large numbers of fibrous balls, these balls are made ​​of dead leaves and you can see all these balls on the shores of countries overlooking the Mediterranean basin. Perhaps this is the way the old seaweed in the notification of humans to their environment at risk. The following picture to a number of these balls.
