Extrachromosomal elements as possible agents of adaptation and development
Abstract
Despite the increasing credence accorded the
concept, the ecology of extrachromosomal elements is still poorly documented, theories concerning their phylogeny and interrelationships are speculative, and the terminology applied to such agents remains confused. In many instances, extrachromosomal elements are regarded as bizarre curiosities that are something
of an epiphenomenon in general evolutionary
biology. The present review attempts to construct a balanced theory of evolution in which proper emphasis is given to possible roles for plasmids and viruses in the processes of growth, adaptation, and speciation.... [Show full abstract]
