Name: $ \qquad $ Date: $ \qquad $ Hour: $ \qquad $ CLADOGRAM ANALYSIS What is a cladogram? It is a diagram that depicts evolutionary relationships among groups. It is based on PHYLOGENY, which is the study of evolutionary relationships. Sometimes a cladogram is called a phylogenetic tree (though technically, there are minor differences between the two). In the past, biologists would group organisms based solely on their physical appearance. Today, with the advances in genetics and biochemistry, biologists can look more closely at individuals to discover their pattern of evolution, and group them accordingly - this strategy is called EVOLUTIONARY CLASSIFICATION CLADISTICS is form of analysis that looks at features of organisms that are considered "innovations", or newer features that serve some kind of purpose. (Think about what the word "innovation" means in regular language.) These characteristics appear in later organisms but not earlier ones and are called DERIVED CHARACTERS. Fill out the following character matrix. Mark an " $ X $ " if an organism has the frait. \begin{tabular}{|l|l|l|l|l|l|} \hline & Cells & Legs & Antenna & Wings & 2 sets of wings \\ \hline Worm & & & & & \\ \hline Spider & & & & & \\ \hline Carpenter Ant & & & & & \\ \hline House fly & & & & & \\ \hline Dragonfly & & & & & \\ \hline \end{tabular} In the box below, create a cladogram based off your matrix.
