A vague 3am thought which has been bugging me.
With the combined efforts of a changing climate, evolving virii and bacteria, increasingly possible nuclear war and the poisoning of our environment for short-term benefits and shorter term bottom lines, extinction of the human species is, at least, a possibility. Oh, and never forget the chance of a stray asteroid impacting on our planet.
At the same time our ever-present human curiosity continues to look for life beyond this planet. There are growing signs that there may well be extra-terrestrial life and proof is being actively sought.
Since homo sapiens first thought of the possibility of life on other planets there has been an assumption that it will be intelligent life. Possibly friendly, possibly hostile.
But intelligent. Evolved from single cells into intelligent beings.
Yet must this be so?
We, as a species, have evolved from earlier species which have not developed intelligence to the level of creating science. Evolution has created many lines of specieal existence, yet only one with ‘human’ intelligence. An attribute which seems to be counter-productive to all other living beings.
Should our intelligent species become extinct, is there any guarantee that another species, of whatever lineage, would develop the intelligence to continue the progress of earthly life to the stars?
There is a distinct possibility that star-gazing, star-reaching intelligence may be a one off, not only on this planet, but also on all planets throughout the Universe.
