This is a list of the longest-living biological organisms: the individual(s) (or in some instances, clones) of a species with the longest natural maximum life spans. For a given species, such a designation may include: The oldest known individual(s) that are currently alive, with verified ages.
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. [2]
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 ...
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 ...
<p>You've probably never heard of a long-extinct organism known as Dickinsonia. Unlike dinosaurs like the Tyrannosaurus rex or more recent extinct beasts like the wooly mammoth, fossils of ...
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 organism is in the shape of a flattened torus, with the long axis of its toroidal body running through the approximate center of the presumed gut cavity. [62] Quilted organisms The organisms considered in Seilacher's revised definition of the Vendobionta [15] share a "quilted" appearance and resembled an inflatable mattress. Sometimes these ...
