How to Make a Cladogram - Boston University
The studnt will learn how a cladogram illustrates an evolutionary hypothesis and makes predictions about evolutionary events (i e the scientific method) 4 The student will learn how cladograms depict relationships between taxa, and represent a “family tree” of life 5 The student will learn how to construct a cladogram from
Cladograms - Integrative Biology
Cladogram of Phyla covered in Bio 11 Cladograms Cladograms are constructed using a method known as ‘cladistics’ This method analyzes a collection of heritable character data compiled by a researcher (morphology and/or DNA) This method groups taxa based on the number of characters that they share with one another Cladograms

a cladogram Here is an example of a cladogram Notice how characteristics such as “jaws” and “fur” appear at certain locations along the branches of the cladogram These locations are the points at which these characteristics first arose You can see that

construct a cladogram, and properly interpret and analyze that cladogram in terms of how it shows common ancestry and degrees of evolutionary relationship D Procedure : Step 1 Using your textbook and the explanations below, determine which of the characteristics each animal has
Cladistics (reading and making of cladograms)
Cladogram – a diagram that depicts the relative levels of relatedness relationships among groups Node – The intersection of two or more branches on a cladogram The node represents an evolutionary split between lineages as well as a hypothetical common ancestors of all taxa higher on the cladogram Evolution – descent with modification
How to Build a Cladogram - SawyerScience
How to Build a Cladogram Background: Cladograms are diagrams that we use to show phylogenies A phylogeny is a hypothesized evolutionary history between species that takes into account things such as physical traits, biochemical traits, and fossil records To build a cladogram one must take into account all of these traits and compare them among
Activity: Create a Cladogram
Step 5 Create the cladogram The long line is the continuation of all the traits you identified in the charts The lines that branch off end in a clade, or a group of organisms with a last common ancestor
