Contrary to what many people think, two species can hybridize naturally in the wild to give rise to a third species, a finding that fundamentally alters our understanding of the evolution of species ...

It has long been thought that dramatic changes in a landscape like the formation of the Andes Mountain range or the Amazon River is the main driver that initiates species to diverge. However, a recent ...

Matías Gómez-Corrales, a recent biological sciences Ph.D. graduate from the University of Rhode Island, and his advisor, Associate Professor Carlos Prada, have published a paper in Nature ...

It's a bit like a character in a movie going off and having adventures that change him so drastically that when he returns, the folks in his hometown no longer recognize the way he looks and behaves.

Researchers emphasize that polyploidy and the important role it has played, especially in plant evolution, would not have gained the recognition it deserves would it not have been for its staunch ...

The shifting songs of Darwin's finches have given new insight into processes that shape the course of evolution, preventing newly forked branches on life's tree from growing back together. The birds ...

The process of speciation allows a single species to diverge into two. Dive into the different versions of this process, including “allopatric speciation” and “sympatric speciation,” and discover how ...

A good way to start an argument among biologists is to ask them what seems a simple question: "What is a species?" To evolutionary theorists, a species is a fundamental unit, and transitions between ...
