Phylogenomics of an Adaptive Radiation
Wild tomatoes contain immense natural trait diversity. This study by Pease et al. describes the evolutionary processes that have generated this diversity over only a few million years, revealing evidence for three unique sources of genetic variation that have fuelled adaptive diversification in this group—postspeciation hybridization, rapid accumulation of new mutations, and recruitment from ancestral variation. The image shows fruit from the wild tomato Solanum pimpinellifolium, a close relative of the domesticated tomato and member of the red-fruited subclade.
