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 ...
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 ...
Mammal species diversified more rapidly early in their history – peaking roughly 66 million years ago – before a long-term decline in diversification punctuated by diminishing bursts of evolutionary ...
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 ...
Evolution, Vol. 68, No. 3 (MARCH 2014), pp. 720-728 (9 pages) In variable environments, selection should favor generalists that maintain fitness across a range of conditions. However, costs of ...
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 ...
A new study has shown that person-to-person variation in antibody immunity plays a key role in shaping which influenza (flu) strains dominate in a population. The work, published today as a Reviewed ...
