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 ...
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 ...
Researchers have found that bird species with multiple plumage color forms within in the same population, evolve into new species faster than those with only one color form, confirming a 60-year-old ...
A recent statistical study has revealed some of the constraints and directions in the evolution of the structure and function of proteins. Better models of protein structural dynamics may allow ...

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 ...
