Six species of swallowtail butterflies occur locally, and they combine yellow, black, orange, blue and red in several diverse patterns that invariably catch the eye. We can marvel at them, but our ...

When most people think about natural selection, they imagine individuals competing with one another: The fastest animal ...

The common view of natural selection is based solely on the individual: A trait allows an organism to out-compete its rivals and is thus passed down to its offspring. To suggest otherwise can provoke ...

How do intermittent events like hurricanes impact natural selection? How do animals adapt to challenging weather? A University of Rhode Island professor has set out to track natural selection in the ...

New research challenges the one-level view of evolution, showing natural selection works on individuals and groups together.

A new mathematical approach for analyzing the complex, subtle patterns of natural mutation in DNA will, according to its developers, help biologists understand how mutation contributes to evolutionary ...

Most of us know that as living things evolve, they take on traits that help them thrive in their home environments. But how are certain traits "chosen" for future generations, and how are others cast ...

A new study led by the University of Rhode Island's Jason Kolbe examines adaptive selection in Anolis lizards in the southeastern U.S. How do intermittent events like hurricanes impact natural ...

A new study by researchers at the University of Wisconsin–Madison provides the first empirical evidence connecting the chromosomal location of genes to natural selection, indicating the arrangement of ...

Charles Darwin’s On the Origin of Species was first published in 1859, introducing much of the world to evolutionary theory. By that time, Darwin had lived through most of the first Industrial ...
