| Intelligent Life Elsewhere In The Universe Likely To Be ‘Exceptionally Rare? |
| Scientists at Oxford University's Future of Humanity Institute looked at the evolution of life on Earth to explore the likelihood of the same thing happening elsewhere – suggest that our chances are pretty slim, given just how rare the circumstances were for Life on Earth. |
| In a Journal article titled The Timing of Evolutionary Transitions Suggests Intelligent Life is Rare argues that life on Earth has seen a number of 'major evolutionary transitions', and that some of these have occurred just once in history - suggesting that they were very rare events, and in turn, so is life as we know it. Their suggestions is based solely upon statistic methodology with low probability of events. |
| The
authors say in the study: "It took approximately 4.5 billion years
for a series of evolutionary transitions resulting in intelligent
life to unfold on Earth and in another billion years, the
increasing luminosity of our Sun will make Earth uninhabitable for
complex life”. |
| The research efforts at retracing the chemical Origins of Life attest to the rarity of it possibly being repeated, especially Intelligent Life. |
| Their conclusion: "In turn, this suggests that intelligent life is likely to be exceptionally rare." |
