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 ...

It’s not often that a paper attempts to take down an entire field. Yet, this past January, that’s precisely what University of New Hampshire assistant philosophy professor Subrena Smith’s paper tried ...

In the article "To Effectively Discuss Evolution, First Define 'Theory'" in the May 12 issue of The Scientist (R. Lewis, page 13), it was stated that the term "theory of evolution" should be replaced ...

IN 1981 PETER and Rosemary Grant, a husband-and-wife team of evolutionary biologists, spotted something odd on Daphne Major. Every year for the previous decade they had travelled from Princeton ...

Over the past 500 million years, nearly all evolutionary changes in octopuses and squids occurred in rapid bursts during the emergence of new species, according to research from the University of ...
