Survey of Branch Support Methods Demonstrates Accuracy, Power, and Robustness of Fast Likelihood-based Approximation Schemes (2011, background): “In particular, support measures are crucial to validating or refuting biological hypotheses on the basis of trees (e.g., Baum et al. 2005).”
Understanding Evolutionary Trees (2008, methodology): “See also the “Tree Thinking Challenge” supplemental quiz by Baum et al. (2005). 3 For the purposes of this discussion and regardless of whether this will annoy some specialists, “evolutionary tree,” “phylogenetic tree,” and “phylogeny” are used interchangeably. Fig. 1 The first evolutionary tree ske”
Active learning and student-centered pedagogy improve student attitudes and performance in introductory biology. (2009, background): “Two striking misconceptions in our class concerned the ability to interpret a phylogenetic tree (see the “tree thinking” exercise by Baum et al., 2005) and the failure to recognize that photosynthetic organisms not only fix CO2 through photosynthesis but also release CO2 through cellular…”
