Recent progress in reconstructing angiosperm phylogeny.

In the past year, the study of angiosperm phylogeny has moved from tentative inferences based on relatively small data matrices into an era of sophisticated, multigene analyses and significantly greater confidence. Recent studies provide both strong statistical support and mutual corroboration for crucial aspects of angiosperm phylogeny. These include identifying the earliest extant lineages of angiosperms, confirming Amborella as the sister of all other angiosperms, confirming some previously proposed lineages and redefining other groups consistent with their phylogeny. This phylogenetic framework enables the exploration of both genotypic and phenotypic diversification among angiosperms.
