2. Fill in a character table that will be used to make the cladogram. The taxon with the least number of derived characters should be the first row. The taxon with the greatest number of derived characters should be the last row.

1. Examples of cladograms from a suitable reference, e.g.Strahler, A.N. "Science & Earth History" . 1987 Prometheus Books. Page 328 (a pdf copy of this can be found at the end of this lesson). Make overhead transparency for class introduction, and/or make copies for students, and attach to background sheet.

Willi Hennig is credited with coming up with a simple rule for reconstructing the evolutionary changes that have occured in a clade that has revolutionized the way comparative biology is carried. First let me contrast phylogenetic analysis ...

To make a cladogram, scientists first collect data on the features of all the organisms they hope to classify. This data is then analyzed to determine which characteristics were present in what could have been a common ancestor and which might have been developed in later times.

The data matrix above has one character that is considered "uninformative." That is the character of "size." Although the character states are "large" and "small," since all the geometric shapes have the character state of "large," there is no way to use the character of "size" to help make the cladogram.

Backtracking through the cladogram is accomplished by clicking on the red circle at the bottom of the cladogram you advanced to. The green circles are there only to make node text easier to read.

This is a story about how short, ... Maybe the first gliding mammals were tiny little things which you wouldn't easily recognize as gliders at all, unless the fossils were very well-preserved and showing the delicate webs. They wouldn't need very long arms or fingers to make it work, but could easily take advantage of big...
