Specimens of the black coral genus Leiopathes, such as Leiopathes glaberrima, are among the oldest continuously living organisms on the planet: around 4,265 years old. [67] Giant barrel sponges can live more than 2,000 years.
Evidence of possibly the oldest forms of life on Earth has been found in hydrothermal vent precipitates. [1]The earliest known life forms on Earth may be as old as 4.1 billion years (or Ga) according to biologically fractionated graphite inside a single zircon grain in the Jack Hills range of Australia.

Formation of a greenstone belt of the Acasta Gneiss of the Slave craton in northwest Canada - the oldest known rock belt. [28] 3900–2500 Ma Cells resembling prokaryotes appear. [29] These first organisms are believed to have been chemoautotrophs, using carbon dioxide as a carbon source and oxidizing inorganic materials to extract energy. 3800 Ma
The Oldest Living Organism Is Over 2 Billion Years Old. Scientists have identified the oldest living species on Earth is a deep sea organism that hasn't evolved in more than two billion years. And ...
A recent study of gelatinous marine creatures revealed a curious ability in which two animals fuse and function as a single organism. The comb jelly, one of the oldest animals on Earth, can fuse ...
The history of life on Earth traces the processes by which living and extinct organisms evolved, from the earliest emergence of life to the present day. Earth formed about 4.5 billion years ago (abbreviated as Ga, for gigaannum) and evidence suggests that life emerged prior to 3.7 Ga. [1] [2] [3] The similarities among all known present-day species indicate that they have diverged through the ...
Although Methuselah is the oldest known non-clonal organism for which a reliable age has been established, the Alerce Milenario in Chile (5,484 years old), [21] [22] Llangernyw Yew in Wales (4,000 – 5,000 years old) and especially the Fortingall Yew in Scotland (3,000 – 9,000 years old) have some age estimates exceeding that of Methuselah.
The tree has since gone on to become one of the oldest organisms in the world at what National Geographic projected to be 13,000 years old. Other estimates clock the self-cloning tree as up to ...
