Neighbor-Joining Method

The neighbor-joining method is a technique used in genetic analysis to build a family tree, called a phylogenetic tree, showing how different species are related. It starts with a list of genetic differences between species and groups the two most similar ones together first. Then, it recalculates the differences considering these groups as single entities, repeating the process until all species are connected. This method efficiently creates a tree that reflects evolutionary relationships based on genetic data, helping researchers understand how species are related over time.
