Scientific paper
Repeatedly, the possibility has been considered that seeds of life or germs have come to earth from space, taking into account questions regarding the place of life's origin. Thus, Richter (1865, 1870) regarded the existence of organic life in the universe as eternal, and thought that seeds or germs could travel through space. Arrhenius (1903, 1908, 1927), who used the term 'panspermia' rather than the earlier word 'cosmozoa', thought seriously about problems of survival of microorganisms in interstellar space. The present paper is concerned with an evaluation of the findings of various authors who have discussed subjects related to the possibility of an arrival of 'panspermia' on earth from some place in the universe. It is concluded that panspermia is not supported by present evidence. However, the possibility of panspermia cannot be completely excluded either. For this reason, an investigation is recommended.
