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 ...

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

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 ...
