These questions, among others (Berendse and Scheffer 2009, Crepet and Niklas 2009) should now be discussed from a late Paleozoic temporal perspective based on evidence presented in the first and second essays. There is growing consensus among some molecular systematists and paleobotanists on the existence of a 160 million year old angiosperm ghost lineage rooted at the angiosperm-gymnosperm split roughly 300 MYA, prior to the end-Permian extinction. Vivian Irish (2006) provides a road map to diversification of the angiosperm clade from the perspective of evo-devo of floral homeotic genes, their phenotypic expression, and molecular phylogenies. Specifically, our results indicate that the heterodimerization between DEF-like and GLO-like proteins was already present in the [most common recent ancestor] MRCA of extant angiosperms and was virtually never rewired" (page 1438, Discussion, Conservation of the MADS-domain protein interaction pattern during angiosperm evolution, Melzer et al. Most of the explosive radiation of floral diversity in basal lineages of flowering plants is explained by duplication and diversification of the MIKC-type MADS-box family of genes (P. The reconstructed physiology and ecology of the Petriellales matches this life form to such detail that we suggest these unusual gymnosperms may represent convergent ecological analogues of early flowering plants" (page 1074, Discussion, Ecology and Paleoenvironment, Bomfleur et al. Taking into account the morphology of reproductive short shoots of Winteraceae (i.e. Hochuli, Palaeontological Institute and Museum, University of Zürich, Zürich, Switzerland. I completely reject the assertion by some workers that angiosperms first appeared in the Cretaceous Period (Feild and Arens 2007). "Angiosperm phylogeny is riddled with examples of convergent morphologies ...
