From: A valid assessment of students’ skill in determining relationships on evolutionary trees
Students interpret evolutionary trees using alternate conceptions. Excerpt transcripts and accompanying evolutionary trees from preliminary interviews. a Student 1 determined the relationship among taxa using morphological and environmental criteria. Student 2 determined the relationship among taxa by counting the number of intervening internal nodes. Student 3 determined the relationship among taxa by identifying how recently they share a MRCA. b Student 3 subsequently used the proximity of taxa at the terminal nodes to answer a separate question
