It usually takes millions of years for new species to evolve, but not for fish in one African lake.

For 50 years, evolutionary theory has emphasized the importance of neutral mutations over adaptive ones in DNA. Real genomic data challenge that assumption. The neutral theory of molecular evolution ...

Despite substantial progress in cancer treatment, durable benefit is still frequently limited by the ability of tumors to adapt under therapeutic pressure.

For more than half a century, many biologists have leaned on the neutral theory of molecular evolution to explain how DNA and proteins change over time. The idea grew from early work in the 1960s, ...

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 ...

LOGAN, UTAH, USA – Understanding the material basis of adaptive evolution has been a central goal in biology dating back to at least the time of Darwin. One focus of current debates is whether ...

A new study reveals the surprisingly convergent evolution in the inner ear of mammals. An international research team showed that a group of highly divergent mammals known as Afrotheria and distantly ...
