Origins of Life in the Universe and Earliest Prokaryotic Microorganisms on Earth

Abstract

The discovery of fossilised life forms or nannobacteria from Martian meteorite ALH 84001 supports the hypothesis that the early evolution of life may have taken place on Mars and earliest prokaryotic microorganisms and first stromatolites similar to the planet Earth around 3.5 billion years might have proliferated on Mars. The eukaryotic algae from the Deoban and the Krol Group of the Himalaya, India has been recorded. There is evidence of vegetative reproduction during Neoproterozoic. Akinites have been reported from Deoban cherts indicative of cell division and the formation of thick cellular wall. Akinite germination have been observed in which they underwent cell divisions to produce a cellular hormogone in Deoban cells.
