I found this interesting article that may go towards affirming the legendary biologist Francis Crick’s (the discoverer of DNA) theory of Directed Panspermia. Panspermia is the the theory that the seeds of life exist throughout the Universe and may have introduced life to Earth. Directed Panspernia goes further and postulates that advanced civilizations wanting to preserve their DNA would distribute it’s organic components intentionally through meteorites and other planetary objects. Crick believed that life on earth was seeded in this way and he stuck with this theory throughout his life. It gave him an unusual yet logical explanation of the amazing complexity of DNA.
Meteorite yields life origin clue
Hollow spheres found in a primordial meteorite could yield clues to the origin of life on Earth.
Scientists say that "bubbles" like those in the Tagish Lake meteorite may have helped along chemical processes important for the emergence of life.
The globules could also be older than our Solar System - their chemistry suggests they formed at about -260C, near "absolute zero".
Details of the work by Nasa scientists are published in the journal Science. Analysis of the bubbles shows they arrived on Earth in the meteorite and are not terrestrial contaminants. These hollow spheres could have provided a protective envelope for the raw organic molecules needed for life.
