'''Directed Panspermia''' posits in regards to the question of [[origin of life]] on [[earth]] that "organisms were deliberately transmitted to the earth by [[Extraterrestrial life|intelligent beings on another planet]]." 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.<ref>http://www.spacedaily.com/news/life-04zzz.html</ref> The abstract for the aforementioned Icarus article stated the following:
