All Life on Earth Could Have Come From Alien Zombies, page 1

Wired Science

Life on Earth could have grown from the broken remains of alien viruses that, although dead, still contained enough information to give rise to new life

In the past, folks have said that life could have come here from 'out there' .. space .. which I agree with totally. But others have said that the radiation involved would kill the life before it got here. Life can't come from dead matter. BUT ... now they are saying they think that it COULD make it happen, even against the odds.

The key lies in how much genetic information survives the trip, Wesson says. An organism’s genetic information is encoded in the sequence of nucleotides in their DNA. This information can be measured in bits in the same way as computer processes. Bacteria like E. coli, for example, carry about 6 million bits of information in their DNA.

Random chemical processes couldn’t produce enough information to run even a simple cell. Over 500 million years, random molecular shuffling would produce only 194 bits of information, Wesson says.

One possible way around this paradox is the idea that life on Earth was seeded by biological molecules that already had a large information content that survived the journey even though the molecules themselves were killed.

Thought ya'll would find it interesting.
The title itself was great.
