- Title
Ever deeper phylogeographies: trees retain the genetic imprint of Tertiary plate tectonics.

- Abstract
Changes in species distributions after the last glacial maximum ( c. 18 000 yearsbp) are beginning to be understood, but information diminishes quickly as one moves further back in time. In this issue of Molecular Ecology, Magri et al. (2007 ) present the fascinating case of a Mediterranean tree species whose populations preserve the genetic imprints of plate tectonic events that took place between 25 million years and 15 million years ago. The study provides a unique insight into the pace of evolution of trees, which, despite interspecific gene flow, can retain a cohesive species identity over timescales long enough to allow the diversification of entire plant and animal genera.
