Symposium on Palynology of the Late Cretaceous and Early ...
... oldest dated fossil remains yet known are about 1 billion years younger than
this, however. The slow accumulation of abiogenically formed molecules, as a
sort of warm organic soup, is sometimes regarded as having involved a billion
years.

From Fossils to Astrobiology: Records of Life on Earth and ...
Structures that resemble these supposed microfossils have also been produced
abiogenically in the laboratory by García Ruiz et al. (2003). With these cautionary
findings in mind, we go on to discover that other claims of putative microfossils ...

The Biological Fractionation of Isotopes
Both in the laboratory and in nature various hydroxy acids, amino acids, and
other more complex compounds can be synthesized abiogenically. Although
chemically they are indistinguishable from their biogenic analogs, their isotopic ...

Genesis and evolutionary development of life
Dissolved in the "primitive soup," nucleotide monomers were assembled purely
abiogenically into randomly built chains of polynucleotides independently of any
catalytic action of proteinlike substances. Rich, using the results of Romberg's ...

Microbial enzymes that oxidize hydrocarbons:
There have been some suggestions that such abiogenically produced
hydrocarbons could have played a role in the origin and evolution of early life (
Martin et al., 2008). Alkane oxidation has evolved in a variety of organisms both
as a strategy ...

Synthesis of Jeewanu: The Protocell
It is difficult to imagine as how the first living system with protein enzyme came in
existence for the first time when the formation of even protein molecule
abiogenically appears so difficult. The process of the abiogenic formation of
organic ...

USSR Space Life Sciences Digest
Optical density of the reduced forms of tetrazole was measured at wavelength of
600 m and compared to a control consisting of tetrazole and the corresponding
catalyst. lt was found that the abiogenically synthesized mealoidins had a ...

Thomas Browne and the Writing of Early Modern Science
... must be examples of His providence and wisdom, creatures He has placed
everywhere, to reproduce abiogenically from mud and feculence. Browne's
continuing interest in the moral emblematics of insects, particularly bees, is very
striking.

Russian Oil Supply: Performance and Prospects
What is also ignored here is the fraction of methane that may have formed
abiogenically. Abio- genic methane may be significant on a crustal abundance
scale, but has not evidenced any role in the supply of natural gas to the human
economy ...
