Molecular evolution is the area of evolutionary biology that studies evolutionary change at the level of the DNA sequence. It includes the study of rates of sequence change, relative importance of ...

A longstanding question in evolutionary biology is how sexual selection influences how entire genomes develop. Sexual ...

Studies have suggested that genes under strong sexual selection tend to evolve rapidly, particularly those associated with male reproductive traits, such as body size or colour. Additionally, genomic ...

Camouflage is a common defensive strategy among animals. By modifying their coloration and patterning, animals evade ...

Along with the Journal of Molecular Evolution and Molecular Biology and Evolution there is now a third journal, Molecular Phylogenetics and Evolution, which will no doubt contribute to the field, as ...

A genetic mutation in horses that would typically halt protein production has become a molecular asset. Researchers at Johns ...

Enzymes originally evolved in high-temperature environments and later adapted to lower temperatures as Earth cooled. Scientists discovered that a key shift in enzyme function occurred over ...

Feathers, essential for thermoregulation, flight, and communication in birds, originate from simple appendages known as proto-feathers, which were present in certain dinosaurs.By studying embryonic ...

The world’s largest multidisciplinary scientific society honored Brown faculty members from molecular biophysics and ...
