what is the oldest living organism?

Answer 1

I believe sequoias

Answer 2

A fungus in MI, if memory serves. I'll google AFTER I submit, 'cos I like to live on the edge.

UPDATE: I found the fungus story, but in googling, I found something that beats 'em all - a 250 million year old /viable/ bacterium.

Bacterial spores of the genus Bacillus were isolated from pockets (inclusions) in salt crystals harvested from an underground salt bed 2,000 feet (610 m) below the surface. The salt deposits were formed from an ancient sea in a geologic formation that dates back about 250 million years. What is so remarkable about these spores is that microbiologists succeeded in growing them in a laboratory. The spores have survived in a cryptobiotic state millions of years before dinosaurs roamed the earth. Another microbe extracted directly from dissolved salt crystals appears to be related to the archaebacteria that thrive in the brine of present-day salt lakes. NASA is interested in ancient salt deposits because the planet Mars and Jupiter's moon Europa once had oceans and may have similar subterranean salt formations. Space missions in search of extraterrestrial life may eventually explore these ancient salt beds. For more about this significant discovery, see the article by R.H. Vreeland, W.D. Rosenzweig and D.W. Powers (2000), "Isolation Of A 250 Million-Year-Old Bacterium From A Primary Salt Crystal," Nature 407: 897-900.

Answer 3

If I am correct, there is a turtle that lives in the Galapagos islands that is the oldest living organism on earth.

Answer 4

Bacteria of the Archae family. This organism can live in the most extreme environments (volcanoes and ice caps).

Answer 5

The Great Basin Bristlecone Pine. Can live 5,000 years!

Answer 6

Probably that lady in China who is 110.

Answer 7

I think its waterbears. I saw it on animal planet.

Answer 8

the prokaryotes archaebacteria and the eubacteria

Answer 9

those damn cockroaches
