Neighbor joining

Neighbor Joining (NJ) is a method used in computational phylogenetics to construct a phylogenetic tree, which represents the evolutionary relationships between a set of species or genetic sequences. It is particularly useful for building trees based on distance data, such as genetic distances derived from molecular sequences. ### Key Features of Neighbor Joining: 1. **Distance-Based Method**: NJ uses a distance matrix that quantifies how different the species or sequences are from one another.
