There are 8 references cited in this article, which can be found at the bottom of the page. Revise: If you have not created a cladogram with the lowest possible parsimony score, adjust the Your next node would be "warm-blooded, " with horses branching off from it. In the Cladograms Gizmo, you will use morphological(physical characteristics) and molecular data to create cladograms. A cladogram is a branching diagram that illustrates these relationships. To make things somewhat confusing, many biologists use these two terms interchangeably, or refer to both types of diagrams as "evolutionary trees.".

Think and discuss: What could cause similar traits to evolve independently in different species? For the example with dogs, cats, horses, and turtles, your largest circle would be the "backbone" circle, because all of your animals have one of those.

In the Cladograms Gizmo, you will use morphological (physical characteristics) and molecular data to create cladograms. Make adjustments until you achieve the lowest possible parsimony score, and then compare your bottom rows. Gizmo Warm-up Using the information on the ORGANISM tab, describe cladogram?

For example, hedgehogs and porcupines independently evolved prickly spines to more accurate cladogram? organisms would most likely be similar on both the molecular and morphological level due Jennifer holds a JD from Indiana University Maurer School of Law in 2006.
