An explicit goal of the Open Tree of Life is to create a single phylogenetic tree that encompasses all living (and some extinct) biodiversity on earth. A question some may have, especially non-scientists, is why do we need a tree like that, and what would we do with it? You can’t even see it all at once, right? The answer to this question, of course, is that with bigger and more resolved trees we can answer evolutionary questions on scales not previously possible.

Currently, postdocs from the labs of Doug Soltis (Univ. of Florida) and Stephen Smith (Univ. of Michigan) are collaborating on several projects within the plant world that leverage the power of big trees. Cody Hinchliff, a postdoc in the Smith lab, recently presented some of these findings during a standing room only presentation at the Botanical Society of America conference in Boise, Idaho, employing a tree with…
