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 ...

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 adaptive evolution relies ...

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 ...

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 ...
