    • Supernatural event

      • The origin of life is a result of a supernatural event—that is, one irretrievably beyond the descriptive powers of physics, chemistry, and other science. Life, particularly simple forms, spontaneously and readily arises from nonliving matter in short periods of time, today as in the past.

    Stages in the origin of life range from the well-understood, such as the habitable Earth and the abiotic synthesis of simple molecules, to the largely unknown, like the derivation of the last universal common ancestor (LUCA) with its complex molecular functionalities. [1]

  4. Sep 19, 2022 · The origin of life on Earth stands as one of the great mysteries of science. Various answers have been proposed, all of which remain unverified. To find out if we are alone in the galaxy, we will need to better understand what geochemical conditions nurtured the first life forms.

  5. Aug 2, 2024 · Although some studies state that life may have begun as early as 4.1 billion years ago, it can be traced to fossils dated to 3.5–3.7 billion years ago, which is still only slightly younger than Earth, which gravitationally accreted into a planet about 4.5 billion years ago. But this is life as a whole.

  6. May 15, 2022 · To account for the origin of life on our earth requires solving several problems: How the organic molecules that define life, e.g. amino acids, nucleotides, were created. How these were assembled into macromolecules, e.g. proteins and nucleic acids, - a process requiring catalysts.

  7. All living things reproduce, copying their genetic material and passing it on to their offspring. Thus, the ability to copy the molecules that encode genetic information is a key step in the origin of life — without it, life could not exist.

  8. In this article, we'll examine scientific ideas about the origin of life on Earth. The when of life's origins ( 3.5billion years ago or more) is well-supported by fossils and radiometric dating.
