Researchers have found that DNA mutations are not random. This changes our understanding of evolution and could one day help researchers breed better crops or even help humans fight cancer. A simple ...

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 ...

A new study examines mathematical models designed to draw inferences about how evolution operates at the level of populations of organisms. The study concludes that such models must be constructed ...

Ironically, one great unsolved problem in Darwin's master work, On the Origin of Species, was just that: How and why do species originate? Darwin and his later followers were faced with a seeming ...

Darwinian thinking has been challenged many times, starting with co-discoverer of natural selection Alfred Russel Wallace, who disagreed with some aspects of Charles Darwin’s arguments, but was ...

Researchers at the University of Maine are theorizing that human beings may be in the midst of a major evolutionary shift — driven not by genes, but by culture. In a paper published in the Oxford ...
