WebA clade (also known as a monophyletic group) is a group of organisms that includes a single ancestor and all of its descendents. Clades represent unbroken lines of evolutionary descent. It's easy to identify a clade using a phylogenetic tree. Just imagine clipping any single branch off the tree. All the lineages on that branch WebNotation A phylogenetic tree is denoted as (˝;q), where ˝is a bifurcating tree topology that represents the evolutionary diversification of the species and qis a vector of the associated non-negative branch lengths for the edges of ˝. The leaf nodes of ˝corre-spond to the labeled observed species and the internal
