Biologists are closing in on a puzzle that seems to turn classic evolutionary logic inside out, yet may be so common that it ...

A major evolutionary theory says most genetic changes don’t really matter, but new evidence suggests that’s not true. Researchers found that helpful mutations happen surprisingly often. The twist is ...

In regressive evolution, organisms lose complex features and can appear to evolve "in reverse." But evolution doesn't retrace its steps, experts said. When you purchase through links on our site, we ...

Environmental change doesn’t affect evolution in a single, predictable way. In large-scale computer simulations, scientists ...

Amphioxus, as a basal chordate, offers an insightful window into the evolutionary origins of vertebrate development. Its embryogenesis, characterised by the formation of a notochord, neural tube and ...

Scientists from the University of Tübingen and Monash University studied glycopeptide antibiotics, a key resource in countering drug-resistant pathogens, to uncover their evolutionary origins to gain ...

A new study by researchers at the Max Planck Institute for Evolutionary Biology (MPI-EB) sheds fresh light on one of the most debated concepts in biology: evolvability. The work provides the first ...

Measuring the pace of evolution is tricky, but some species can evolve as quickly as a few generations. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it ...

In fact, it's happened so often that there's a scientific term for it: carcinization. If you close your eyes and think of a crab, you might picture a round, flat body. Big front claws and multiple ...

The hypothalamus is a small but critical region at the base of the brain that controls the autonomic nervous system, regulates body temperature, signals hunger and thirst, exerts hormonal control over ...
