«This is an interesting example where mild mutations in a gene that is critical for normal development leads to phenotypic [observable] evolution,» said lead researcher Leif Andersson, a professor of functional genomics at Uppsala University, the Swedish University of Agricultural Sciences, and Texas A&M University.

Khila said it's rare for experiments to be able to bring together biomechanics, transcriptomics, evolutionary biology, ecology and developmental genetics, but that combination is what's needed to provide a complete answer to how phenotypic evolution occurs.

With this unique resource in hand, we have already characterized several candidate structural variation which show evidence for phenotypic adaptation, which can function to drive species evolution,» said Emerson.

For genome evolution driven by selection there are observations of various phenotypic correlates consistent across both mammals and birds.

Besides ensuring correct chromosome segregation during the first meiotic division, crossovers create new allele combinations in gametes, thereby increasing genomic diversity, increasing the chance of creating offsprings with better phenotypic fitness, and providing the basis for faster evolution.

These dynamics are the basis for models that predict the evolution of clade frequencies, as well as broad genetic and phenotypic changes.

Moreover, variation in breeding success between males is a main source of phenotypic selection pressures, and, hence, elephant seals are a modal species for the study of sexual selection and evolution of secondary sexual traits.

Any projected adverse impacts of rising temperatures or declining seawater and freshwater pH levels («acidification») will be largely mitigated through phenotypic adaptation or evolution during the many decades to centuries it is expected to take for pH levels to fall.
