Abstract:
If we were to describe all the species on Earth and determine their distributions, we would solve the popularly termed 'Linnean' and 'Wallacean' shortfalls in biodiversity conservation. Even so, we would still be hindered by a 'Darwinian shortfall', that is, the lack of relevant phylogenetic information for most organisms. Overall, there are too few comprehensive phylogenies, large uncertainties in the estimation of divergence times, and, most critically, unknown evolutionary models linking phylogenies to relevant ecological traits and life history variation. Here, we discuss these issues and offer suggestions for further research to support evolutionary-based conservation planning.
