Roughly 300,000 years ago, our species first appeared on the African landscape before spreading globally and coming to dominate the planet. All this happened about 4.5 billion years after Earth formed,

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

Scientists challenge the idea that intelligent life is rare. They argue that evolution follows planetary changes, not random luck.

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.
