The image above is the northwestern face of the Korombasabasaga Range, Viti Levu Island, Fiji as viewed from the road between Namosi and Wainimakutu villages. A review of neotenous development in termites is available (Korb and Hartfelder 2008). Structurally similar to bioactive plant brassinosteroids, 20E-ecdysone induces a cascade of TF biosynthesis important in the regulation of insect development (Truman and Riddiford 2002, De Loof 2008). One line of paleobiological thinking hypothesizes that insects took flight to exploit new habitat. Did ingestion of seed plant brassinosteroids by pterygote insects affect the evo-devo of wings from thoracic limb pads and JH signaling?
Evolutionary-development of arthropod- and plant organs and molecular tool kits is "highly dynamic in evolutionary time" involving the evolution of cis-acting promoters (page 83, Baum 1998). Reviews by Rothwell (1987), Arthur (2002), Meyerowitz (2002), Becker and Theißen (Figure 1, page 468, 2003), Niklas (2006), Rothwell et al. A key paper on the control of insect body size by Nijhout (2003) outlines the molecular mechanisms involving cis-acting TFs and hormones and environmental controls (nutrition and temperature) behind growth and cell division in hemimetabolous and holometabolous insects.
The clade probably first appeared during Triassic times, possibly as a result of the re-setting of plant evolutionary history following the devastating global extinction event of the Permian Triassic boundary ..." (4. The fossil dataset used by the Cascales-Miñana team is grossly incomplete. Simply put, paleontologic data are required to calibrate and validate molecular phylogenies (Peterson et al. "The interface of these three subject areas (Figure 1 on Page 778), molecular evolution, evolutionary developmental ('evo-devo') biology, and palaeoecology, is the theme of Molecular Palaeobiology, as it [the approach] uniquely integrates the patterns written in the two historical records, genomic and geological ... Labandeira's findings (2014) might also help disprove the notion of a Hauterivian (Lower Cretaceous) origin of flowering plants (Hughes 1994, Friis et al. Errors in molecular-phylogenetic inference may result from effects of LBA (Barrett and Willis 2001, Magallón 2010, Zhenxiang Xi et al. Paraphyly may be underappreciated (Krassilov 2002, Stuessy 2010) and effects on seed plant evolution attributable to possible HT might cloud our understanding of relationships among basal clades of the angiosperm crown group (Bergthorsson et al. "Darwin himself referred to the 'early origin and diversification of angiosperms' as 'an abominable mystery,' and the origin of the flower- and therefore flowering plants- is still a question ..." (page 86, Pamela S. Soltis 2014) Molecular-phylogenetic analyses by Magallón (page 395, 2010) when calibrated with fossil data and compared with different relaxed-clock methods "... Coevolution between phytophagous insect antagonists and Carboniferous, Permian, and Triassic seed plant hosts at the level of their respective developmental tool kits with focus on selective forces that drive the logic of transcriptional regulation is proposed to explain the origin of angiosperms and certain clades of holometabolous insects.
Modern syntheses on the abominable mystery of the origin of angiosperms from unknown Paleozoic seed plant ancestors and modern radiations are published by Frohlich and Chase (2007), Maheshwari (2007), Sokolov and Timonin (2007), Zavada (2007), J. After integrating evidence as a whole with our results, the resulting scenario suggests that there is nothing particularly mysterious about the diversification of angiosperms during Cretaceous times or how it is reflected in the fossil record. The preceding statement is an optimistic appraisal of methodology used by Cascales-Miñana et al. Some "current viewpoints" are left out of the analysis. The preceding statement is from page 35 of Armen Takhtajan (1969), Flowering Plants: Origin and Dispersal (translated by C. Conrad Labandeira is apparently less than enthusiastic on the idea of a coevolutionary origin of the group (2014). "Tight coevolution" between animal disperser and plant was probably rare (page 3, Tiffney 2004). 2007) expressed as often disarticulated and shed, wood-, pollen-, seed-, foliar-, and cone- and floral- organs preserved in the fragmentary rock record of the Carboniferous, Permian, and Triassic periods.
(2014), have contributed to our knowledge of the origin and evolution of flowering plants. fossil-based, molecular, phylogenetic and paleobiogeographic studies) and current viewpoints about the explosive Cretaceous diversification of angiosperms. Further, problems associated with co-radiations of angiosperms and insects are brought to light by phylogenetics (T. 2007) suggesting that evolution of certain clades of late Mesozoic phytophagous ants, bees, beetles, butterflies, flies, and moths might be independent of the explosive origin and spread of eudicot orders and families (Labandeira 2014). Root Gorelick (2001) challenges the validity of a biotic coevolutionary hypothesis on the origin of flowering plants. Deciphering the ancestry of flowering plants and their paleoecologies probably requires an understanding of the paleontology of "fingerprints of developmental regulation" (quoted from page 723, Sanders et al.

"We have examined herein different methodological approaches (i.e. Donoghue (2007), Molecular Palaeobiology, Palaeontology 50(4): 775-804. Presumed co-radiations of flowering plants with chrysomelid beetles are asynchronous (Gómez-Zurita et al. (2014) and Becker (2016), which are determined by expression of CRMs, GRNs, PINs, and TFs.
