“…to Earth (panspermia hypothesis, Arrhenius, 1903;Richter, 1865). The panspermia hypothesis has actually been proposed about 2500 years ago by Anaxagoras, a Greek philosopher (Warmflash and Weiss, 2005). The hypothesis for transport through space was based on solar radiation propelling the organisms.…”

“…Also, there is no known way to generate life as we know it from a piece of DNA, partly because the instructions for the genetic code are not in the code itself, and damaged molecules do not have the transcription and translation abilities usually considered necessary for life. This problem may in principle be partly avoided by appeal to other properties of nucleotides or other molecules such as RNA (Trevors and Abel 2004;Warmflash and Weiss 2006). However, it must be admitted that all versions of panspermia suffer from a hole in our knowledge, concerning how to go from an astrophysically-delivered entity which contains substantial information to one which has the characteristics of what we normally regard as life.…”

“…This is possible in principle, and can work in practice inside the solar system (see below); but is disfavoured for transport over larger distances by statistical arguments (Horneck et al 2001;Wallis and Wickramasinghe 2004;Adams and Spergel 2005;Warmflash and Weiss 2006). The chances are best when boulders are ejected from the surfaces of planets in orbit around stars which are themselves in some kind of populous cluster.…”

Astronomically, there are viable mechanisms for distributing organic material throughout the Milky Way. Biologically, the destructive effects of ultraviolet light and cosmic rays means that the majority of organisms arrive broken and dead on a new world. The likelihood of conventional forms of panspermia must therefore be considered low. However, the information content of damaged biological molecules might serve to seed new life (necropanspermia).
