A strange tiny species of crustacean has challenged the way we think about natural selection and evolution. This microscopic animal, known as a water flea or Daphnia pulex, generates genetic variation ...

New research suggests that natural selection, famous for rewarding advantageous differences in organisms, can also preserve similarities. The researchers worked with a plant called wild radish and its ...

When most people think about natural selection, they imagine individuals competing with one another: The fastest animal escapes predators, the strongest plant produces more seeds, and the most ...

Study of 280 empirical papers suggests evolution is shaped by both individual advantage and competition between groups.

In natural populations, the mechanisms of evolution do not act in isolation. This is crucially important to conservation geneticists, who grapple with the implications of these evolutionary processes ...

Antibiotic resistance, when infection-causing bacteria evolve so they are no longer affected by typical antibiotics, is a global concern. New research at the University of Tokyo has mapped the ...

Learn how repeated burn injuries may have acted as a form of natural selection, influencing human genes linked to healing and immune response. Fire transformed human society in obvious ways. Less ...
