We may all be space aliens: study
Genetic material from outer space found in a meteorite in Australia may well have played a key role in the origin of life on Earth, according to a study to be published Sunday.
European and US scientists have proved for the first time that two bits of genetic coding, called nucleobases, contained in the meteor fragment, are truly extraterrestrial.
Previous studies had suggested that the space rocks, which hit Earth some 40 years ago, might have been contaminated upon impact.
Both of the molecules identified, uracil and xanthine, "are present in our DNA and RNA," said lead author Zita Martins, a researcher at Imperial College London.

As I recall the seed group was from the first sentients that formed, lived and died long before the other races appeared. Directed panspermia is the phrase used in scientific speculation.

Star Trek the Next Generation had an episode dealing with exactly this concept. It deals with the primordial soup being peppered with the DNA that is the basis of us all.
It is most amazing as time progresses that Science Fiction in its highest form precedes factual discovery.
