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 ...

The conservation of genome regulatory elements over long periods of evolution is not limited to vertebrates, as previously ...

For a long time, evolutionary biologists have thought that the genetic mutations that drive the evolution of genes and proteins are largely neutral: they're neither good nor bad, but just ordinary ...

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 ...

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 ...
