About Phylogenetic Tree Maker
The Phylogenetic Tree Maker builds cladograms from character matrices using UPGMA distance-based clustering. Add species, define traits as present or absent, and generate a rooted phylogenetic tree with synapomorphies labeled at each branching point.
Includes pre-loaded examples for vertebrates, plants, and primates. Perfect for biology students studying evolution and taxonomy.
FAQ
A phylogenetic tree is a branching diagram showing evolutionary relationships among species based on shared characteristics and common ancestry.
Parsimony is the principle that the simplest explanation is preferred. Maximum parsimony selects the tree requiring the fewest evolutionary changes to explain the observed data.
Read from the root outward. Each branching point represents a common ancestor. Species sharing a more recent node are more closely related. Branch labels show synapomorphies that define each clade.
Synapomorphies are shared derived characters — traits that evolved in a common ancestor and are inherited by all its descendants. They define monophyletic groups (clades) on a phylogenetic tree.
