A cladogram is a diagram that communicates the path of common ancestry between a group of organisms. A node in the diagram indicates a common ancestor. Nodes higher on the cladogram are more recent ancestors, those further down are more ancient.

In the evaluation of the Gallotia species of the canary islands we evaluated multiple types of evidence to help us arrive produce a cladogram that is best supported by the available evidence.

Prepare a final cladogram that represents your best model based upon the evidence. Record a screencast that:

Shows a neat, (hopefully computer generated) version of your cladogram.

Pictures you in the video.

Is less than 2 minutes.

Explains what the cladogram is showing about who shares very recent ancestors and who does not.

Discusses the types of data you evaluated and which data was most influential to your final cladogram.

Identifies where lines of data pointed to different conclusions.
