Maximum levels of global phylogenetic diversity efficiently capture plant services for humankind

Abstract

The divergent nature of evolution suggests that securing the human benefits that are directly provided by biodiversity may require counting on disparate lineages of the Tree of Life. However, quantitative evidence supporting this claim is still tenuous. Here, we draw on a global review of plant-use records demonstrating that maximum levels of phylogenetic diversity capture significantly greater numbers of plant-use records than random selection of taxa. Our study establishes an empirical foundation that links evolutionary history to human wellbeing, and it will serve as a discussion baseline to promote better-grounded accounts of the services that are directly provided by biodiversity.
