Today on Far Future Horizons we are going to explore the possibility of life elsewhere in the Cosmos. Whatever form life takes on elsewhere in the cosmos we can be reasonably certain that the same inexorable laws of evolution through natural selection that shaped life on Earth will shape it elsewhere. Natural selection has given rise to an incredible diversity of life on this planet. Over the past four billion years, this has resulted in a plethora of living organisms each adapted and specialize to occupy a particular ecological niche and eventually the emergence of new species. If life exists elsewhere we can very well expect it to reflect and perhaps surpass the almost inconceivable variety of life on our world. Yet when studying the wonderful history of life on our planet we are faced with a spectacular conundrum. Natural selection has shaped and sculpted an incredible life form that appears to be able to adapt to life in every conceivable ecological niche. A life form that is on the verge of directing the course of its own evolutionary future and also of creating life forms that will transcend biology in silico. And, that life form is us – Homo sapiens. We are the pioneers of a whole new form of evolution which is distinctly non-biological. This new realm of evolution is Cultural Evolution. It is this new dominion of evolution that has made us the most dominant life form on this planet and has set us on a trajectory that will one day take us out amongst the stars. Will we one day encounter other such life forms or their living machines out amongst the starry ferment? ...Self-reproducing probes or robots, free from such restraints [Darwinian evolution], could advance by Lamarckian evolution. That is, they could pass on directly any acquired abilities and desired improvements to the next generation, and evolve rapidly capabilities beyond the reach of biological beings. - Edward Ashpole, The Search for Extra-terrestrial Intelligence Then the future struggle for existence may indeed be between the biological and non-biological entities played out on a galactic scale. We will explore these questions in a later series of articles. In the meantime enjoy today’s video offering as we explore the possibility of life in Darwin’s Universe.
