theory proposes that clay particles act as a catalyst to turn simple organic molecules into more complex structures - starting the process of life.

(Frankfurt: Springer, 1999).
Furthermore, it has been suggested in the scientific literature that life may have been purposely directed to Earth (directed panspermia
The concept of Panspermia
- that life on Earth originated in space - is an ancient one,' said Dr Wickramasinghe, who spends his days at work staring at the skies.
Popularized 100 years ago by Swedish Nobel laureate Svante Arrhenius, panspermia
suggests that radiation pressure may have protected living spores as they traveled through space, possibly via comets.
The original panspermia
theory did not say that the spores were intentionally sent to other planets, but merely said that microbes in space brought life to planets like the earth.
Los temas son variados: la teoria de supercuerdas, los campos morfogeneticos, la memoria holografica, los agujeros de gusano, la teoria de la panspermia
, por mencionar algunos.
Their findings have been contested, but the meteorite renewed enthusiasm for the idea of panspermia
(Greek: all-seeding)--the interstellar exchange of DNA, a theory that was championed by Francis Crick, who discovered the DNA molecule with two other scientists hall a century ago.
Sin embargo, la opinion de Haeckel no tenia en cuenta una tercera hipotesis, igualmente alejada del creacionismo y de la generacion espontanea, la hipotesis de la panspermia
, que contaba con tan eminentes defensores como el gran quimico Justus von Liebig y el prestigioso fisico y fisiologo Hermann Helmholtz.
As a result, this panspermia
hypothesis argues that life reached the Earth from deep space and, once these seeds took root, more and more advanced plants and animals emerged on our planet.
is when the same life forms created somewhere else in the universe are able to initiate life on other planets.
The paper does not deal with how panspermia
