In one, intelligent life like humans generally arises very quickly on planets, geologically speaking – in perhaps millions of years. In another, it typically arises in about the time it took on ...

Intelligent life may develop on planets as a rule, not an exception — increasing the odds of humanity existing beyond Earth, according to a new study. Researchers from Penn State University ...

The evolution of humans on Earth may not be entirely exceptional. That is because intelligent life is likely to form if certain planetary conditions are met, a new study suggests. This idea ...

The path toward intelligent life, they argue, may be more of a predictable process, unfolding as global conditions allow in a manner that should not be considered unique to Earth.

Intelligent life, on the other hand, isn’t nearly as likely. Based on his calculations, Kipping puts the odds at around 3:2 in favor of intelligent life, but notes that even on Earth, ...

Scientists propose a new idea about why intelligent life hasn't contacted humanity. A planet would need continents, oceans, and plate tectonics for a civilization to emerge in a galaxy.

Intelligent life may be extremely rare in our universe, according to Princeton University Astrophysical Sciences Professor Ed Turner. This view is not surprising, since intelligence is also rare ...

Evolving intelligent life took billions of years—but it may not have been as unlikely as many scientists predicted. by Daniel Brady Mills, Jason Wright and Jennifer L. Macalady, The Conversation ...
