(2017) compile particularly relevant reference lists. Flowering material of Degeneria vitiensis is shown in the right-hand image (photographed by Paddy Ryan, Ph. Fragrance of this species resembles Cananga odorata according to Professor Al Smith (A. While discussing the effects of ice-house/hot house planetary climatic switches on expansion of land plant invertebrate herbivores Labandeira (2006) states: "One possibility is that these atmospheric variables have direct physiologic consequences on the selection and turnover of particular plant clades globally, which in turn elicit an associational response from selected clades of insect herbivores." The preceding statement is quoted from page 425 of C. Labandeira (2006), The four phases of plant-arthropod associations in deep time, Geologica Acta 4(4): 409-438. Additional compilations on the origin of angiosperms and floral morphology include Krassilov (1991), Thorne (1992), Endress (1993, 2001 [a book chapter and two papers], 2004), Friedman (1992 [two papers]), Stewart and Rothwell (1993), Nixon et al. Studies on Drosophila melanogaster eggs, specifically, artificial size-selection experimentation, affects larval patterning and body allometry (Miles et al. Do host seed plant brassinolides and other hormones affect insect antagonist egg size, potentially controlling larval tissue patterning? At the very earliest, flying insects were known from the Devonian Period. The International Journal of Plant Sciences devotes most of Number 7 of Volume 169 (2008) toward the ongoing search for the earliest flowers, based on an international symposium held during the summer of 2007 at the Swedish Museum of Natural History (von Balthazar et al. More than twenty articles in Volume 96, Number 1 of the American Journal of Botany explore the origin, evolution, and radiation of flowering plants to celebrate the Charles Darwin Bicentennial (Stockey et al. Conrad Labandeira's several reviews on fossil insect-plant phytophagous associations (Labandeira 2000, 2006, 2007 [two papers], 2010, 2014) contain extensive bibliographies. 2008) and assembly of chitin and cuticle proteins into the exoskeleton (Charles 2010, Moussian 2010). Another Hox protein Abd-B, when combined with the Dsx enzyme, represses expression of the wg gene in fruit flies (W. I also add hexamerin moulting storage proteins which are related to hemocyanin respiratory enzymes (Burmester et al. 2006, Burmester and Hankein 2007), JH esterases, vitellogenin genes and yolk proteins (Isoe and Hagedorn 2007), pheromone chemoreceptors (Robertson and Wanner 2006), and certain nuclear receptor proteins (Bonneton et al. 2008) including ultraspiracle, and ecdysone inducible TFs to the list of molecular developmental tools among early diverging arthropod lineages. The first appearance of insect wings in the rock record of the Paleozoic Era has yet to be established. The three essays on the succeeding web pages are written from this research perspective. Gómez-Zurita and Galián (2005) discuss the utility of molecular phylogenetic characters appearing in the entomological literature in a review paper, which is organized along the lines of Floyd and Bowman (2007) for land plants (see section below). Understanding the land plant developmental tool kit and gene regulation from a deep time research perspective ties-in with models of cone and floral organization, cell geometry and regulation of growth from SAMs, paleobiology of homeodomain TF trafficking, phyllotaxis, leaf development, and morphogenesis of fertile organs. Were insect and shrub coevolutionary compartments of the late Paleozoic hypoxic icehouse and later hot house, venues of the first angiosperms? This question among others is explored in this first of three essays on the origin of angiosperms. Long-branch attraction (LBA) continues to cloud molecular-phylogenetic studies of seed plants, including angiosperms (Lipeng Zeng et al. Evolutionary-development of early land plants was probably intertwined with regulatory changes in polycomb repressive 2 gene complexes and other stem cell factors as evidenced from studies of the extant model bryophyte Physcomitrella (Okano et al. Floyd and Bowman (2007) are the first workers to estimate the developmental tool kit of early land plants including Paleozoic seed plant homeotic genes potentially important in the later evolution and diversification of angiosperms and origin of the first flowers from bisexual cone axes sensu Melzer et al. The work by Floyd and Bowman (2007) focuses on a molecular-phylogenetic analysis of Chara (a green alga), Physcomitrella (a moss), Selaginella (a lycophyte), Arabidopsis (angiosperm malvid), Antirrhinum (angiosperm asterid), Oryza (angiosperm monocot), Populus (angiosperm fabid), Picea (gymnosperm conifer), and Pinus (among others). I discuss potential coevolution of insect and seed plant helix-turn-helix proteins, specifically Engraled and Leafy enzymes that bind to cis-regulatory promoters controlling downstream expression of genes determining paedomorphic insect body patterns and plant cone and floral organ development. (2017) report low support ( The Fiji Islands have long been of interest to biogeographers (Raven and Axelrod 1974, Thorne 1986, Morley 2001), to geologists as a tectonic puzzle (Rodda and Kroenke 1984), and to botanists as a "cradle of flowering plants" (title, Chapter 12, Takhtajan 1969), where some "missing links in the chain of angiosperm phylogeny" are known (page 141, Between Assam and Fiji, Takhtajan 1969). There are several conifers endemic to the Fiji Archipelago including Agathis vitiensis, Acmopyle sahniana, Dacrycarpus imbricatus, Dacrydium nausoriense, Dacrydium nidulum, and Decussocarpus vitiensis. The only known species at the time, Degeneria vitiensis (pictured below), combines a number of primitive features that have ignited many debates (I. Some paleontologists regard the problem of flowering plant origins, "... Juvenile hormone and its homologs are integral in vitellogenesis (Hartfelder 2000), regulation of moult cycles (Truman and Riddiford 2002), and caste development and behavior in social Hymenoptera (Guidugli et al. Were bioactive brassinolides and sesquiterpenes manufactured by Paleozoic seed plants used as chemical warfare agents to affect growth, development, and behaviour of herbivorous insects? Another avenue of deduction somehow ties-in insect evo-devo of wings from gill halteres with increases in atmospheric oxygen during the De CARB. The place and time to begin a molecular phylogenetic analysis is the late Frasnian-Famennian Age hypoxic icehouse that extended into the Tornaisian Age of the Carboniferous Period.
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?

Family: Her parents were the primary suspects in the case for over a decade, but were finally cleared in 2008, two years after Patsy died of ovarian cancer (Jon Benet, John, Patsy and Burke in their 1993 Christmas photo)The body of Jon Benet was found bludgeoned and strangled hours after she was reported missing and covered by a white blanket with a nylon cord around her neck, her wrists bound above her head and her mouth covered by duct tape.
On Christmas Day of 1996, the family received a ransom note saying they had kidnapped Jon Benet and were demanding 8,000 - the amount of a bonus Mr Ramsey had recently received - or else she would be beheaded.
