Cladistics (ancient Greek: , klados , "branch") is a form of biological systematics which classifies living organisms on the basis of shared ancestry. It can be distinguished from other taxonomic s...

A cladogram is a stylized diagram that looks like a series of Y's or forks in a road. At each branch, or "Y" junction, novel characters of evolutionary origin are ... The process of constructing a cladogram begins with data; a table of traits or characteristics that have evolved or been derived by the evolutionary process.

2. Given a cladogram, the student will properly interpret and analyze that cladogram in terms of recognizing the concepts of common ancestry and degrees of evolutionary relationship. ... 3. Given a cladogram of vertebrates and some new "unclassified" vertebrates, the student will show where the new animals would be placed.

The shared derived features of the homologous structures are shown on the cladogram by solid square boxes along the branches, ... On the cladogram, close relationships are shown by a recent fork from the supporting branch. The closer the fork in the branch between two organisms, the closer is their relationship.

1. Start with a list of taxa that are to be fit into the cladogram (the ingroup) and their derived characters. Choose an outgroup; a taxa that shares a primitive character with the ingroup, but exhibits none of the derived characters.

Welcome to the first ever online cladogram practice Web site. This online assignment will help you get more comfortable with cladograms. They are not as confusing as you probably thought they were. After completing the following steps, you will be on your way.

This cladogram can be written several ways. The most inclusive group always goes at the top, by convention. However, we could describe precisely the same set of relationships like this: ... But we can see what they are posited to be and can challenge the cladogram with evidence. It is testable, unlike a Linnaean scheme.

Encyclopedia information on Cladogram ... A cladogram is a tree-like diagram showing evolutionary relationships. Any two branch tips sharing the same immediate node are most closely related. All taxa that can be traced directly to one node (that is they are "upstream of a node") are said to be members of a monophyletic group.

A cladogram is a branching diagram representing the most parsimonious distribution of derived characters within a set of taxa. We may use this distribution as an hypothesis of the evolutionary propinquity [(kinship)] of those organisms.
