Spores are another type of these seeds that survive inhospitable and extremely harsh environments. The structural form of spores that form the life cycle of some algae and fungi are highly resilient to ultraviolet and gamma radiations. The spores stay in an inactive state until conditions that favor germination sweep across regardless of time taken. Space borne organic molecules and structures have been found in meteorites (NASA, 2009). The report is based on an astonishing discovery of a strain of amino acid that is one of primary chemical building-blocks of basic life after analysis of the comet rocks.
According to Lurquin (2003) bacteria spores drifted through space, landed by chance on earth, germinated and started the process of evolution. This was an interesting idea and it solved the problems of origin of life on Earth.
Although there are different variations of the hypothesis, the meaning is that it attempts to explain the beginning of life on earth.
