Complex cells are thought to be the result of a union between two ancient microorganisms, but scientists have long been ...

STARKVILLE, Miss.—Mississippi State biologist Matthew W. Brown, the university’s Donald L. Hall Professor of Biology, is part of an international research team whose groundbreaking discovery is ...

Researchers investigating the origin of complex life on Earth might have just made a major breakthrough. The origin of humanity and the planet Earth is probably debated more than whether the chicken ...

Life’s leap from single-celled to multicellular organisms marks a pivotal moment in evolutionary history. This transformation laid the foundation for the complex life forms we see today. By studying ...

Assembly Theory is a way to understand how the complexity of life emerged through a mechanism of “self-assembly.” It could explain how life formed on Earth—or other planets—via the shortest path to ...

Most days you move through the world without thinking about the invisible creatures that surround you. Yet one of them, a tiny marine organism called Solarion arienae, is quietly reshaping what you ...

A biochemist, building on the pillars of evolutionary theory and drawing on cutting-edge research into the link between energy and genes, argues that the evolution of multicellular life was the result ...

For decades, experts have tried to explain how simple cells evolved into the complex organisms that make up plants, animals ...

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 ...

The catastrophic impact of an asteroid 66 million years ago brought death and devastation on Earth—but also fascinating new life.
