MILLER,3 DAVID M. ROHR,4 AND WILLIAM E.

The leaves are simple, symmetrical, mostly oblong or elliptical, and vary in length from 1.2 to about 35 ern. The petioles are short and stout, with a basally enlarged abscission zone. The margins are crenate, with a narrow, indurated border. Venation is in 4 orders: the secondaries and tertiaries are robust, unbranched, and pinnately arranged in a precise "herringbone" pattern, with the secondaries ending in the marginal sinuses; the quaternaries divide sparingly and fuse with others to form a dense reticulum ofsmall meshes. Permineralized petiole and midrib material reflects a bifacial cambium, shown by a semicircular vascular arc, irregularly divided into several collateral bundles with secondary xylem and phloem. Delnortea is referable to the Gigantopteridaceae, a probably artificial family of gymnosperms incertae sedis with important venation features in common, but without known diagnostic reproductive organs. With Delnortea. the North American gigantopterids now include 5 genera, but Gigan­ topteris itselfis lacking.

Tiffney Department of Geological Sciences, University of California, Santa Barbara, California 93106; email: [email protected] KeyWords angiosperm, gymnosperm, fossil seed, fossil fruit, evolution, coevolution ■ Abstract Vertebrate dispersal of fruits and seeds is a common feature of many modern angiosperms and gymnosperms, yet the evolution and frequency of this fea- ture in the fossil record remain unclear. Increasingly complex information suggests that (a) plants had the necessary morphological features for vertebrate dispersal by the Pennsylvanian, but possibly in the absence of clear vertebrate dispersal agents; (b)vertebrate herbivores first diversified in the Permian, and consistent dispersal re- lationships became possible; (c) the Mesozoic was dominated by large herbivorous dinosaurs, possible sources of diffuse, whole-plant dispersal; (d) simultaneously, sev- eral groups of small vertebrates, including lizards and, in the later Mesozoic, birds and mammals, could have established more specific vertebrate-plant associations, but supporting evidence is rudimentary; and (e) the diversification of small mammals and birds in the Tertiary established a consistent basis for organ-level interactions, allowing for the widespread occurrence of biotic dispersal in gymnosperms and angiosperms.

Paleontologists employ a wide variety of metrics to assess differences in herbivory 14 among assemblages: damage type diversity, intensity (the proportion of leaves, or of leaf surface area, 15 with insect damage), the evenness of diversity, and comparisons of the evenness and diversity of the flora 16 to the evenness and diversity of damage types. Although the number of metrics calculated is quite large, 17 given the amount of data that is usually available, the study of insect herbivory in the fossil record still 18 lacks a quantitative framework that can be used to distinguish among different causes of increased insect 19 herbivory and to generate null hypotheses of the magnitude of changes in insect herbivory over time.

  • Natural Selection Drives the Evolution of Ant Life Cycles
    PERSPECTIVE PERSPECTIVE Natural selection drives the evolution of ant life cycles Edward O. Wilsona,1 and Martin A. Nowakb aMuseum of Comparative Zoology, Harvard University, Cambridge, MA 02138; and bProgram for Evolutionary Dynamics, Department of Organismic and Evolutionary Biology, and Department of Mathematics, Harvard University, Cambridge, MA 02138 Contributed by Edward O. Wilson, June 9, 2014 (sent for review December 17, 2013) The genetic origin of advanced social organization has long been one of the outstanding problems of evolutionary biology. Here we present an analysis of the major steps in ant evolution, based for the first time, to our knowledge, on combined recent advances in paleontology, phylogeny, and the study of contemporary life histories. We provide evidence of the causal forces of natural selection shaping several key phenomena: (i) the relative lateness and rarity in geological time of the emergence of eusociality in ants and other animal phylads; (ii) the prevalence of monogamy at the time of evolutionary origin; and (iii) the female-biased sex allocation observed in many ant species. We argue that a clear understanding of the evolution of social insects can emerge if, in addition to relatedness-based arguments, we take into account key factors of natural history and study how natural selection acts on alleles that modify social behavior. sociobiology | claustrality | adaptive radiation | inadequacy of inclusive fitness Comparative studies have revealed that from in the primitive termite species Zootermopsis insects, especially ants, leading to super- the moment of the evolutionary origin of nevadensis.
