Origin Of Life

The earliest life on Earth existed more than 3.5 billion years ago, during the Eoarchean Era when sufficient crust had solidified following the molten Hadean Eon. The earliest physical evidence so far found consists of microfossils in the Nuvvuagittuq Greenstone Belt of Northern Quebec, in "banded iron formation" rocks at least 3.77 billion and possibly 4.28 billion years old.

Life - Blogger

Definitions The definition of life has long been a challenge for scientists and philosophers, with many varied definitions put forward. [9] [10] [11] This is partially because life is a process, not a substance. [12] [13] [14] This is complied by a lack of knowledge of the characteristics of living entities, if any, that may have developed outside of Earth.


Acetonitrile is the chemical compound with the formula CH3CN. This colourless liquid is the simplest organic nitrile (hydrogen cyanide is a simpler nitrile, but the cyanide anion is not classed as organic). It is produced mainly as a byproduct of acrylonitrile manufacture. It is used as a polar aprotic solvent in organic synthesis and in the purifiion of butadiene. In the laboratory, it is
