A bold new theory of intelligent life and origin of humanity
- Humanity and other forms of intelligent life in the universe may not be as extraordinary or improbable as previously thought, according to a new theory.
- A new model suggests that humanity could be the probable outcome of biological and planetary evolution, challenging the 'hard steps' theory of human evolution.
- This theory proposes that humanity's evolution on Earth might not be a series of lucky events but a natural evolutionary outcome.
- The study published in Science Advances on February 14, 2025, challenges the notion that humanity is a unique and rare product of planetary evolution.
- Researchers argue that intelligent life may not require lucky breaks to exist and that human evolution may be less about luck and more about environmental factors.
- The evolution of humans became possible when the global environment reached a permissive state, including suitable conditions like oxygen availability.
- The study uses Earth's geological timescale instead of the sun's lifespan to understand the emergence of intelligent life, suggesting it may not be as unlikely as previously thought.
- The interdisciplinary approach of this new theory involves physicists and geobiologists, challenging the old 'hard-steps' model based in astrophysics.
- This new perspective opens up exciting avenues of research to understand the origins of life and the potential existence of similar life forms elsewhere in the universe.
- In summary, the rise of humanity and other intelligent life forms might not have been purely by chance, but rather a probable outcome of evolutionary processes.
