Author(s): Aniruddha Uniyal*
Discovery of many extra solar planets with some of them having conditions favourable to harbour life have raised
hopes for earth alike biological destinies and evolutionary consequences elsewhere in the universe. This paper is
an attempt to hypothesize the earth a like evolution and biological destiny for emergence of Extra-Terrestrial Life
(ETL) and Extra-Terrestrial Intelligence (ETI) on an exoplanet. Extraterrestrial life could be unimaginably different
in its form, shape, composition, dimension, functionality, evolution and even in biochemistry from the life that
evolved on earth and might be inconceivable to us. Therefore, some innovative ways and means of detection of
extraterrestrial life are also being discussed, so as to keep the possibilities of detection alive. Furthermore, an attempt
has been made to modify the Drake equation for quantifying our ne sci.. View more»
