Convergent phenotypic evolution often results from similar genetic changes in independent species by a process known as parallel evolution. Sometimes, convergent evolution results from the evolution ...

Top: The ninespine stickleback, Pungitus pungitus, is typical of the saltwater form. Bottom: A freshwater form of stickleback with fewer bony plates and fewer spines. Image based on drawings from the ...

Parallel evolution is the independent evolution of similar traits, starting from a similar ancestral condition. Frequently this is the situation in more closely related lineages, where several species ...

An important question in evolutionary genetics concerns the extent to which adaptive convergence in protein function is caused by convergent or parallel changes at the amino acid level. Even when ...

Few technologies have a more interesting history than parallel computing, in which multiple processors in a single system combine to tackle a problem. A chronicle of events in parallel computing says ...
