What is the Oldest Living Organism?

Posted Jan 25, 2007 by Chris V. Thangham

Scientists find bacteria and estimate its age to 250 Million Years and King's Holly tree to be 43,000 Years old.
Of all the world records profiled on Extreme Science this one has proved to be the most elusive and tricky to keep updated. It seems there are a number of different organisms that hold the record for the "longest lived" and their exact ages are still under investigation. In fact, the only thing we can report for certain is that the records listed here will probably be upstaged by a new discovery in the near future.
The Extreme Science has listed the oldest living organisms, some of them are so old and still many are to be discovered. In 1999, Scientists found one bacteria in an ancient sea salt beneath Carlsbad, New Mexico and was in a suspended animation stage (similar to hibernation only it was forced) in a hard shelled spore for an estimated 250 Million Years. They revived this in a laboratory and is living now. In May 1995, they found another 40 Million Year Old bacteria in the bee's stomach encased in amber in a similar suspended animation stage and was revived. In 1997, Scientists found a King's Holly tree (shown in Picture) in Australia and estimated its age between 43,000 years old. These plants can neither produce Flowers or Seeds, they only multiply by splitting of roots. The found leaves of this plant as fossils and estimate its age from that to be 43,000 years old and their genetics matches exactly with this living plant. And there are few more, in August, 1999, they found Box Huckleberry (Gaylussacia brachycera) in Pennsylvania and estimate its age to be over 13,000 years old. In March, 2004, Eucalyptus recurva also known as "Mongarlowe Mallee" or "Ice Age Gum" it is the rarest Eucalypt in Australia or the world estimate its age to be 13,000 years old. In 1980; Creosote bush (Larrea tridentata) was discovered by Scientists estimated to be between 11,000 and 12,000 years old.
Besides bacteria I thought, only Sequoia tree which is estimated to be 2000 to 2500 years are the oldest trees, but this list is amazing. There are also some old pine trees that can also live a longer time.
