Intelligent Life May Be More Likely to Exist on Other Planets Than Previously Thought, Scientists Say
Researchers present an alternative to the long-held “hard steps” theory to explain the evolution of complex life, suggesting it’s the natural outcome of a habitable environment rather than a lucky bre
Intelligent Aliens May Be Common On Earth-Like Planets, Scientists Say
A new study rewrites the story of human evolution, suggesting that intelligent life is not rare but a natural planetary process rather than an improbable event.
Life might be much more likely than we realised, scientists say – and it could help us find aliens
If so, that has important effects for life throughout the universe. It suggests that life might have been likely to form elsewhere, too – and that alien life could be waiting in more places than we thought. The “hard steps” theory had suggested that life was probably rare: it would need a whole host of things to go right to begin.
Evolving intelligent life took billions of years − but it may not have been as unlikely as many scientists predicted
We suggest that as the Earth changed physically and chemically over time, its surface conditions allowed for a greater diversity of habitats for life. And these changes operate on geologic timescales – billions of years – explaining why the proposed hard steps evolved when they did, and not much earlier.
Intelligent Aliens May Be All Across the Universe, a Controversial New Theory Suggests
According to an alternative model of how intelligent life emerges on planets like Earth, the existence of aliens—and human beings–could be the result of natural planetary processes.
Alien life is 'only a matter of time' - if they're not out there already, scientists say
Scientists have said that in a cosmos filled with trillions of stars, intelligent alien life will form ‘in only a matter of time’. If it hasn’t already, that is. Many astronomers say that for life to form,
Humans evolved to live on an icy planet. Earth is usually much hotter.
As Earth approaches warmer levels experienced earlier in its geologic history, it may be bad news for human survival.
