BIOL 3454 1st Edition Lecture 5 Current LectureI. Example exam phylogeny problemsII. = character evolves III. = character doesn’t evolveIV. 1 = character is present V. 0 = character absent Example:Charater 1 2 3A 1 0 0Taxa B 1 1 0C 1 1 1 C B A 321I. A, B & C all have character 1 in common II. B & C have character 2 in commonIII. C has character 3IV. Easier to evolve something once than it is multiple timesV. 2 is phylogeneticly informative VI. B & C are more alike than B to A or A to C Example:Character 1 2 3 4 5A 1 0 0 0 0Taxa B 1 1 0 0 0C 1 1 1 0 0These notes represent a detailed interpretation of the professor’s lecture.
