What is a Cladogram?

What is a Cladogram?

An evolutionary tree that shows the relationships among organisms is called a cladogram. Cladograms were drawn in the past based on similar phenotypes or physical traits. Cladograms can also be drawn today based on the similarities in DNA sequences between organisms.

How to Create a Cladogram in Your Classroom?

  1. Decide on what to cover

Select the area you want to cover including the group of organisms and the specific questions that you want to cover via the cladogram.

  1. Divide the class into groups

Divide the class into small groups. Assign each group a cladogram for a specific subset of organisms. Each group should choose four to six organisms to be in their cladogram. Those organisms must be in the same family or order.

Assign each group a dedicated folder and workspace to work on. Provide necessary access and permissions to edit. Share the workspace easily via an email or link.

  1. Collect data

Advice on how to collect data. Each group should collect data on the physical and genetic characteristics of the organisms they are focusing on. Data should include information on morphological features, DNA sequences, etc.

  1. Identify characters and determine character states

After collecting the required data, each group should focus on identifying characteristics useful for creating the cladogram. They should determine and assign the possible states for each character. For example, in morphological features, the states may be present or absent. Use Creately’s powerful table function to format the data.

Here is a more thorough breakdown to follow:

  • Select one ancestral and one derived characteristic to designate the outgroup. What do all of these organisms have in common? The purpose of the ancestral characteristic is to link the animal in the outgroup with other animals. It also serves as a comparison point.

  • Pick derived characteristics for the ingroup (Part 1). How are organisms in the ingroup different from one another?

  • Pick derived characteristics for the ingroup (Part 2). After separating the organisms, it is time to separate them from each other.

  • By this point, your group should have derived characteristics for each animal in the ingroup such that you could make a sort of list of them, from ancestral to most derived. For each derived characteristic chosen, the organisms with and those without the characteristic should be separated.

  1. Create the cladograms

Use a pre-drawn Creately template or create one from scratch to visualize each cladogram. Based on character states assigned to each organism, each group can now create their own cladogram.

In the assigned workspace, guide each group on how to drag and drop shapes, import images and draw connections.

  1. Analyze and interpret the cladograms

Analyze each cladogram to understand the evolutionary relationships between the organisms. The groups should be encouraged to interpret the results according to their know-how.

Each group can include their results and interpretations as sticky notes or in the notes panel. Show the class how to include additional information for each element in the notes panel to expand their research and to use the diagram as an information repository for further analysis.

  1. Share each group’s results with the class

Get together and present each cladogram and findings. Discuss any similarities or differences. Use frames, colors and advanced formatting to create interactive presentations.

After each presentation, encourage the class to leave comments right on the canvas for feedback.

  1. Review and revise

Review and revise as necessary.

FAQs About Creately’s Cladogram Maker

How do you read a cladogram?
The main line of a cladogram represents the passage of time. The start of the line is the furthest back in the past, typically millions of years ago. The nodes of a cladogram represent common ancestors that evolved a particular physical trait or characteristic.
What is the difference between a cladogram and a phylogenetic tree?
A cladogram is based on characteristics while a phylogenetic tree is based on genetics. The relationships cladograms show are hypothetical, meaning they haven’t been proven genetically. In contrast, the relationships shown on a phylogenetic tree are backed by molecular evidence.
Can I export the cladograms I create into other documents?
Yes, Creately comes with a host of export options. You can choose to export your cladogram in SVG, PNG, JPEG or PDF formats and use the file downloaded to add to reports and presentations. You could also share a viewable link to your Creately workspace and make a presentation straight from the canvas.
Can I add images into my cladograms?
With Creately you can import images directly onto the canvas. From the ‘assets’ function you can add images from your machine or directly search and add images available on Google.
