New research has found that a genetic variant which reduces the chance of contracting diseases such as tuberculosis and leprosy is more prevalent in populations with long histories of urban living.
University of Maryland biologists have identified how changes in both behavior and genetics led to the evolution of the Mexican blind cavefish (Astyanax mexicanus) from its sighted, surface-dwelling ancestor.
An interactive computer model helps teach students about evolution.
A unique experiment at Rice University that forces bacteria into a head-to-head competition for evolutionary dominance has yielded new insights about the way Darwinian selection plays out at the molecular level.
A study led by scientists from the Royal Botanic Gardens, Kew's Jodrell Laboratory, which focuses on epigenetics in European common marsh orchids, has revealed that some plants may be able to adapt more quickly to environmental change than previously thought.
Plant scientists at the John Innes Centre have provided a new solution to an old debate on why species hybrids can be more vigourous than their parents.
ROCHESTER, N.Y., July 9 /PRNewswire-USNewswire/ -- It has been a basic principle of evolution for more than a century that plants and animals can adapt genetically in ways that help them better survive and reproduce.
A new paper by a team of researchers led by University of Notre Dame biologist Jeffrey Feder could herald an important shift in thinking about the genomics of speciation.
By using entire islands as experimental laboratories, two Dartmouth biologists have performed one of the largest manipulations of natural selection ever conducted in a wild animal population.
To look at the tobacco budworm moth and its close cousin, you wouldnâ€™t be able to tell the fuzzy-looking, fingertip-size moths apart.
