Organisms that reach “peak fitness” still keep evolving, even with no external pressures pushing them towards survival.

Evolution describes changes in inherited traits of populations through successive generations. To fully understand the ...

(Stanley45/E+/Getty Images) The basics of evolution are pretty straightforward to grasp: organisms better equipped to survive ...

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 ...

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 ...

Tuberculosis is the world's deadliest infectious disease, due in part to its ability to hide out for years in the lungs before starting an infection. Now, a new computational method developed by ...

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 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 ...

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 ...

Computer programs designed to “evolve” solutions to mathematical problems support the idea that complexity in nature emerges in small, often apparently unremarkable, steps. Complex biological ...
