the theory proposed by FRANCIS CRICK and LESLIE ORGEL in 1973. according to my teachers, it is a way by which life originated on earth. "sperms" or "pollen" from outer space landed on earth and contaminated it, leading to the development of life. its also called the COZMIC THEORY and of-course, they both won the Nobel prize for it. however, the internet has other points and stories regarding this. if you ask me, i think that they both haven't yet mentioned a clear-cut reason as to how exactly life originated(..in outer space in this case). in short, pan here means outer and spermia means sperm. hope it helped :)

THEORY OF PANSPERMIA or COSMOZOIC THEORY is given by Richter.Helmholtz and Arrehinus suggested that life reached the earth from some heavenly body through meteorites. PANSPERMIA[ as suggested by Arrhenius is primitive form of life]consisted of spores or seeds and microbes that existed throughout universe and produced different forms of life on earth.
