In the 1996 book Darwin’s Dangerous Idea, the philosopher Daniel Dennett argues that evolution might be the best idea anyone ever came up with. “If I were to give an award,” Dennett writes, “I’d give ...

A major event in the evolution of organisms on earth was the development of complex, multicellular life forms made of eukaryotic cells, which are thought to have come from prokaryotic cells. Studies ...

A new analysis of roughly 25,000 amino acid substitutions from evolved E. coli shows that adaptive laboratory evolution ...

Small really does seem to be beautiful in evolutionary terms. The largest dinosaurs, pterosaurs and mammals may look impressive but these giants are vastly outnumbered by microscopic bacteria and ...

Experimental evolution harnesses controlled laboratory regimes to unravel the principles of genetic adaptation across generations. By exposing replicate populations of microorganisms, invertebrates ...

Dr. Luis Buatois (Ph.D.) traces a series of hexagons with his finger, following the path carved by tiny organisms millions of years ago that have long since left these unique fossils in their wake. It ...

The study shows that it’s possible to model how competition for resources, symbiosis or predation shapes the evolution and survival of species. Erin Malsbury The Evolution of Terrestrial Ecosystems ...

How will life on Earth and the ecosystems that support it adapt to climate change? Which species will go extinct – or evolve into something new? How will microbes develop further resistance to ...

The process of speciation allows a single species to diverge into two. Dive into the different versions of this process, including “allopatric speciation” and “sympatric speciation,” and discover how ...

The intersection of human evolution and Earth’s environmental history brings together two areas of scientific study with exceptionally high public visibility and broad societal interest—human ...
