Evolution of influenza : ウィキペディア英語版 | Evolution of influenza
The virus causing influenza is one of the best known pathogens found in various species. In particular, the virus is found in birds as well as mammals including horses, pigs, and humans.〔'〕 The phylogeny, or the evolutionary history of a particular species, is an important component when analyzing the evolution of influenza. Phylogenetic trees are graphical models of the relationships between various species. They can be used to trace the virus back to particular species and show how organisms that look so different may be so closely related.〔 ==Mechanisms of evolution== Two common mechanisms by which viruses evolve are reassortment and genetic drift.〔'〕
