Cryptic genetic variation (CGV) is genetic variation that normally has little or no effect on phenotype but that, under atypical conditions that were rare in the history of a population, generates ...

In a study, published in Science Advances, an international team of researchers have identified 28 gene regions that have been particularly important in the evolution of Darwin's finches. These ...

Morphological diversity is generated by a continually shifting balance between variation and constraint. As modern evolutionary biology takes advantage of an enormous wealth of genetic and genomic ...

A pair of studies sheds new light on genetic variation that may have played a key role in human evolution. The study researchers used an animal model to study a gene variant that could have helped ...

Identifying complex mutations in the structure of an organism's genome has been difficult. But ecologists and evolutionary biologists have applied new methods of genome analysis to identify these ...

Cerion uva (L.) and Tudora megacheilos (Potiez and Michaud) are the dominant land snails of Aruba, Bonaire and Curaçao; both display the high degree of intraspecific character variation so often noted ...

Hadropus Schoenherr, 1826 is a monotypic genus of Naupactini (Curculionidae: Entiminae), ranging in Brazil and Paraguay. It is easily recognized by the nebulose pattern of the elytral vestiture, the ...
