Sexual dimorphism is one of the most prevalent, and often the most extreme, examples of phenotypic variation within species, and arises primarily from genomic variation that is shared between females ...

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 ...

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 ...

Natural selection generally favours phenotypic variability in camouflaged organisms, whereas aposematic organisms are expected to evolve a more uniform warning coloration. However, no comprehensive ...

Introduction. Definition of natural selection ; Relationship to genetic drift and evolution ; Restricted meanings of "natural selection" ; Modes of selection ; Summary -- Philosophical comments.

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 ...

For years, the story of recent human evolution looked relatively quiet. Scientists studying ancient human DNA had found only a few dozen clear cases where natural selection appeared to strongly favor ...
