Swirling masses of gas and dust which made up the sun formed by collisions of space debri.
-
The collision between earth and space debri released thermal energy.
-
The archael species methanosaecina banker; produces methane in the metabolism stage. Archaea are thought to be simliar to the types of cellular life one.

-
Spallanzani's experiment --> was a spontaneous generation of microorganisms.
-
Thomas Cech --> He was able to work with cytalists (1947)
