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 ...

Humanity may not be extraordinary but rather the natural evolutionary outcome for our planet and likely others, according to a new model for how intelligent life developed on Earth. Humanity may not ...

A new suggestion that complexity increases over time, not just in living organisms but in the nonliving world, promises to rewrite notions of time and evolution. In 1950 the Italian physicist Enrico ...

It is the ultimate mystery of biology: How did life begin? A team of Harvard scientists has brought us closer to an answer by creating artificial cell-like chemical systems that simulate metabolism, ...

In a groundbreaking discovery, scientists at Trinity College Dublin have identified a "universal thermal performance curve" that governs how all living organisms respond to temperature. This finding ...

In the coming decades, we might figure out how to make an entirely new kind of life: a mirror cell, in which every molecule is the mirror image of those found in normal cells. Such reversed cells have ...

Evolution supporters argue: Courts have affirmed evolution's place in education. Creationism is just a belief, not based on empirical data, and not testable. Creationism undermines critical thinking ...
