Published in Science 310 (5750) pp. 979-980.

Summary from publisher:
Phylogenetic trees are widely used to study the relationships among living species and genes. In their Perspective, Baum et al. discuss how it has become apparent that trees are commonly misunderstood, leading to confusion about the concept of common ancestry. Although challenging, tree thinking should be taught as an element of evolution training at all levels.

Two tree-thinking quizzes were published as supplemental materials to this paper.
