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 ...

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 ...

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 ...

The present theory offers a unified solution to three closely related evolutionary problems. (1) Why does an evolving population explore only a small fraction of the accessible pathways in genotype ...

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 ...

Coccolithophores are microscopic algae that form tiny limestone plates, called coccoliths, around their single cells. They are responsible for half of the limestone produced in the oceans and ...

Believe it or not, evolution isn’t blind or random chance. It is the natural result of having an advantage, even if it is very slight, that makes the difference between dying young or living to ...

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 ...
