A phylogenetic tree is arranged in a branching pattern that shows the relationships between different organisms or groups of organisms based on their evolutionary history. The tree is usually depicted with a single ancestral species at the base, and each branch represents a different lineage or evolutionary path. The branches can further divide into smaller branches, representing the divergence of different species or groups of organisms from a common ancestor. The arrangement of the branches in the tree indicates the relatedness and evolutionary distance between different organisms or groups.
