Natural selection causes genetic variants that increase fitness to spread within a population. Individuals bearing such alleles will leave behind more descendants and those descendants …
The environments in which animals live are complex and disruptive. These qualities contrast with the steady, smooth, and stereotyped movements that comprise foundational studies in …
As a malaria patient takes and metabolizes weekly doses of an anti-malarial pyrimethamine, there is a periodic change in drug concentration. The growth rate, or …
Most mutations that occur in biological systems are deleterious. It is of fundamental interest to understand how natural populations can evolve to cope with this. …
Reciprocal recombinant F2 populations of the fruitfly were created and analyzed using a pooled whole-genome sequencing approach to investigate the effects of divergent mitochondrial DNA …
An elongate ‘snake-like’ body form has evolved more than 65 times within vertebrates and is present within almost every major clade. Of the disparate taxa …
Transposons are parasitic DNA sequences that pose threats to genome stability across a range of eukaryotes. To defend against transposition into essential genes and destabilizing …
Knowledge of genetic diversity within natural populations, how this variation is maintained, and its underlying selective drivers are central to both evolutionary ecology and biological …
Concentric (shortening) and isometric (constant-length) muscle contractions are well documented across tetrapod species. Less is known, however, about how fish differentiate uses of concentric and …
Statistical and computational methods for detecting evolutionary processes in human genomic data have been going through rapid advances across multiple fields of study and timescales. …
