So many things had to happen for us (humans) to end up here (Earth). Our species is made possible because a water-filled planet orbits a particular distance away from a star of a particular size.

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 displaces ...

For decades, many scientists have relied on the "hard steps" model to suggest that intelligent life is rare — the improbable result of a series of unlikely evolutionary leaps. But new research by ...
