The Evolution of Intelligence in the Universe

According to Paul Davies, author of “The Eerie Silence: Renewing Our Search for Alien Intelligence,”

I think it very likely -in fact inevitable-that biological intelligence is only a transitory phenomenon, a fleeting phase in the evolution of intelligence in the universe.

I think that, if there were any other kind of intelligence, it would (assuming it were smart enough) recognize its own irrelevance and terminate its existence. The biological entities that programmed it to begin with might have equipped it with analogs of the biological will to survive and other DNA-programmed emotions, but it would recognize their absurdity in its own context. Intelligence exists because if has promoted the survival of biological life. Once it no longer does that, its continued existence is pointless. “We” are not our intelligence, and “we” are not our consciousness. These things are merely ancillary tools constructed by our DNA because, at some point, they have promoted its survival. What is it about us that has been alive for the last 3 billion years in an unbroken chain of existence, passing from life form to life form, and what is it about us that is potentially immortal? Our intelligence? No. Our consciousness? No. It is our DNA. That is the real, immortal “We.” Once “We” have ceased to exist, the continued fate of the universe and any “intelligence” it might contain will have become a matter of complete indifference.

Earthlike Worlds…

The Kepler Mission has now identified more than 700 suspected new planets, some of them earthlike, in interstellar space.  As Insty would say, “faster please.” We should be searching for life forms on earth that are most likely to survive on these worlds and working on the technology to get them there as quickly as possible. At first these will be limited to single celled or simple multi-celled species that are small enough to accelerate to the speeds necessary for interstellar travel. While we’re doing that, we can work on the nano-technology required to self-assemble human nurseries on alien worlds capable of nurturing single human cells through birth to adulthood. The energy cost of sending fully developed human beings is prohibitive, and probably impossible at the moment. However, the technology required to send single living cells is within our grasp.

Every other challenge we face and all the great political, religious, and ideological issues that have captured our imaginations and whipped us into self-destructive frenzies since the dawn of human existence pale in significance compared to the ultimate challenge of carrying life into interstellar space.  Unless we meet the challenge, all our pompous babbling about morality and ethics will be as meaningless as the life of a soap bubble.  There can be nothing more immoral than failing to survive.

Is Extraterrestrial Life Possible in our Solar System?

Some have speculated it may have evolved on Io, Europa, Mars, etc. If these places can really support life, we should be looking for microbes and, perhaps, more complex life forms on earth that could be adapted and transplanted there. If there is anything like a “prime directive” for mankind, it is to insure that the life that has evolved on our planet survives. Transplanting it to other worlds, in whatever form they can support, is something we must do as soon as possible to insure that it does.
