A team of researchers at NYU Abu Dhabi (NYUAD) has uncovered how a common color variation in frogs has helped them thrive and ...

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 ...

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 ...

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 ...

Researchers at the Texas A&M School of Veterinary Medicine & Biomedical Sciences (VMBS) and an interdisciplinary team of collaborators have uncovered new information about the history of cat evolution ...

The concept of phenotypic trade-offs is a central element in evolutionary theory. In general, phenotypic models assume a fixed trade-off function, whereas quantitative genetic theory predicts that the ...

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 ...

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 ...

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 ...
