Examine the caminalcules carefully referring to the following diagram showing their morphological characters B C D Character Anterior Appendages Eyes Posterior Appendag State 1 Tentacles Firs Present Absent Sucker Anterior Ridge Present Dorsal Ridas Absent Present Posterior i Assent Present State 0 A Le Bum Greidar Triangular tel B Absent 2 C Use the above data matrix you just created to compile the number of synapomorphic traits between each pair of caminalcule species in this table by dragging and dropping the appropriate numbers 0 6 D State 2 D Lass Legs E Arend W 8 Dal Proge OG 0 0 0 O CM A L Eyee s p oppentage O a Ob to complete the data matrix below by dragging either 0 1 or 2 character states Watch the lecture 7 50 of the answer is in there CHARACTER STATE Eyes CHARACTER OG A Anterior Appendages 0000 000000 BCDE Fosterior Appendages 00 Auterio Ridge00 Dorsal Ridge 000000 Potetice R00 Lateral Bump 00000 7 Now you can use these data to cluster your caminalcule species nto a tree that represents their phylogeny based on parsimony Which of the following trees is the most parsimonious tree The parsimony principle is basic to all science and tells us to choose the simplest scientific explanation that fits the evidence In terms of tree building that means that all other things being equal the best hypothesis is the one that requires the fewest evolutionary changes I hope you answered a in the previous question Now let s ma one of the traits eyes onto th most parsimonious tree Drag a drop the traits so that you minimize the steps OG B C D A
