Neighbour joining method phylogenetic tree
WebMay 17, 2009 · Neighbor Joining (NJ) is a so-called distance-based method that, thanks to its good accuracy and speed, has been embraced by the phylogeny community. It takes the distances between n taxa and produces in Θ ( n 3) time a phylogenetic tree, i.e., a tree which aims to describe the evolutionary history of the taxa.
