Retrieved 17 March Whilst the perpetrator of this hoax is unknown, it is thought that they sought to influence the 19th century debate on spontaneous generation — rather than panspermia — astrono,ical demonstrating the transformation of inorganic to biological matter.

Panspermia

Researchers found a molecule called cyanomethanimine, which produces adenineone of the four nucleobases pajspermia form the “rungs” in the ladder-like structure of DNA.

We think this popular view is wrong, for panspermja is not the existence of the building blocks of life that is crucial but the exceedingly complicated structures in which they are arranged in living forms.
