Directed Panspermia posits in regards to the question of origin of life on earth that "organisms were deliberately transmitted to the earth by intelligent beings on another planet."[1] In 1973, Francis Crick and the chemist Leslie Orgel published an article in the International Journal of Solar System Studies (Icarus) which presented their Directed Panspermia proposal to the origin of life on earth.[2] The abstract for the aforementioned Icarus article stated the following:
| “ | It now seems unlikely that extraterrestrial living organisms could have reached the earth either as spores driven by the radiation pressure from another star or as living organisms imbedded in a meteorite.
As an alternative to these nineteenth-century mechanisms, we have considered Directed Panspermia, the theory that organisms were deliberately transmitted to the earth by intelligent beings on another planet. We conclude that it is possible that life reached the earth in this way, but that the scientific evidence is inadequate at the present time to say anything about the probability.[3] |
