Therefore the authors propose the theory of Directed Panspermia where an intelligent civilization from another planet would intentionally infect the Earth with microorganisms by means of a special long-range unmanned spaceship.
Example of directed panspermia. Directed panspermia is the term for a speculative theory of how life began on Earth. Panspermia and directed panspermia are subsets of exogenesis. An early example of the idea of directed panspermia dates to the early science fiction work Last.
Exogenesis is the general idea that life originated somewhere other than Earth and then somehow migrated here. For example Gold 1960 has suggested that we might have evolved from the microorganisms inadvertently DIRECTED PANSPERMIA left behind by some previous visitors from another planet for example in their garbage. Many enzymes for example require this metal to act as a cofactor.
Nineteenth-century mechanisms we have considered Directed Panspermia the theory thatorganismswere deliberately transmitted to the earth by intelligent beings on another planet. The two main types of panspermia genesis are 1 Deliberate or Directed Panspermia the view that the seeds of life were deliberately brought to. We draw attention to the kinds of evidence that might.
The attitude of such a civilization toward humanity would have to. Directed panspermia Wikipedia. Here we wish to examine a very specific form of Directed Panspermia.
Conversely active directed panspermia has been proposed to secure and expand life in space. Directed panspermia thus appears to be an example of the logical fallacyof infinite regression and thus violative of Occams razor. Crick and Orgel further suggested that directed panspermia might help resolve one or two anomalies in the biochemistry of life-forms on Earth.
The article however does not mention by what mechanisms the generation of complex organisms from the planted microorganisms would arise. Directed panspermia proponents are few in number as this mechanistic option calls for intelligent intention of the seeding of life on earth. Nanocraft could travel at 20 the speed of light making the journey to Proxima Centauri in just 20 years.
