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

"This dual effect—reduced volcanic carbon release and enhanced geological carbon storage—cooled Earth's climate and altered ocean chemistry, creating conditions suitable for the evolution of more ...

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 ...

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 molecular clock theory posits that genetic changes happen steadily and gradually, offering a reliable means for peering into the past and theorizing when complex life first emerged. However, there ...

This figure presents a modern tree of Life, highlighting eukaryotes (organisms with complex cells) based on genome-scale analyses from Valt et al. (2025). The newly identified and ancient supergroup ...

The team has proposed a new evidence-based scenario for the emergence of complex life they have called ‘CALM’ - Complex Archaeon, Late Mitochondrion. Complex life began to develop earlier, and over a ...

Add Yahoo as a preferred source to see more of our stories on Google. All life on Earth can be traced back to a Last Universal Common Ancestor, or LUCA. A study suggests that this organism likely ...

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 ...

Physical principles of evolution / Peter Schuster -- The interplay of replication, variation and selection in the dynamics of evolving populations / Richard A. Blythe -- A simple general model of ...

Ten years ago, I would have turned my nose up at the idea that we already understood how to get machines to think. In the 2010s, my team at Google Research was working on a wide variety of ...
