Theoretical research indicates that natural selection will increase existing seasonal imbalances between the supply of nectar from flowers and the demand from bees and other insects.
An unusually cold winter in the U.S. in 2014 took a toll on the green anole lizard, a tree-dwelling creature common to the southeastern United States. A new study offers a rare view of natural selecti...
What matters more for the evolution of plants and animals, precipitation or temperature? Scientists have found a surprising answer: rain and snow may play a more important role than how hot or cold it...
Natural selection can act on all the expressed genes of an individual, leaving signatures of genetic differeniation or diversity at many loci across the genome. New power to assay these genome-wide ef...
AMHERST, Mass. – Introducing a new approach that combines evolutionary and engineering analyses to identify the targets of natural selection, researchers report in the current issue of Evolution that ...
The Price equation partitions total evolutionary change into two components. The first component provides an abstract expression of natural selection. The second component subsumes all other evolution...
Aquatic prey species respond to predators with fast (developmental) and slow (selective) feedbacks. Natural selection is assumed to fashion details of induction and to modify baseline morphology, but ...
