Slide #1. Slide 1 Slide #2. The Species-Scape (from Quentin Wheeler, based on data from E. O. Wilson) Slide #3. A reconstruction of the single known colony of Pheidole nasutoides, found at La Selva, Costa Rica (painting by Katherine Brown-Wing) Slide #4. William Morton Wheeler’s 1910 illustration of Pheidole tepicana is the classic depiction of castes in ants. <BR> <BR>P. tepicana is one of several members of the genus that possess continuous polymorphism in the worker caste, culminating at the upper size range in a supermajor. Slide #5. Unit trays of Pheidole species as seen in the collection of the Harvard Museum of Comparative Zoology <BR>(from Rarest of the Rare, by Nancy Pick, 2004) Slide #6. Published by <BR>Harvard University Press, <BR>March 1, 2003 Slide #7. Pheidole mooreorum <BR> (p. 209 in Pheidole in the New World: A dominant, hyperdiverse ant genus, by E. O. Wilson, 2003) Slide #8. Pheidole perryorum new species Major, lateral view Slide #9. Phylogeny of the major subfamilies of ants, inferred from morphological, molecular, and fossil evidence <BR> <BR> <BR> <BR> <BR> Slide #10. Phylogeny of the hominines (B. Wood and P. Constantino, in J. Cracraft and M. J. Donoghue, eds., Assembling the Tree of Life, Oxford, 2004, p. 532) Slide #11. Phylogeny of animals A, consensus from literature B, modification by present authors (D. J. Eernisse and K. J. Peterson, in J. Cracraft and M. J. Donoghue, eds., Assembling the Tree of Life, Oxford, 2004, p. 198) Slide #12. Phylogeny of the basidiomycete fungi (left), and examples of various fruiting bodies (right) (J. W. Taylor et al., in J. Cracraft and M. J. Donoghue, eds., Assembling the Tree of Life, Oxford, 2004, p. 179) Slide #13. Vascular plant phylogeny (K. M. Pryer et al., in J. Cracraft and M. J. Donoghue, eds., Assembling the Tree of Life, Oxford, 2004, p. 146) Slide #14. Radiation of Eukarya Crown radiation: the single branch that gave rise to the familiar eukaryan kingdoms such as animals, plants, and green algae. Thick branches: relative no. SSU rRNA units (N. R. Pace, in J. Cracraft and M. J. Donoghue, eds., Assembling the Tree of Life, Oxford, 2004, p. 83) Slide #15. Phylogeny of Retroviridae genera (left) and Poxviridae (right) (D. P. Mindell et al., in J. Cracraft and M. J. Donoghue, eds., Assembling the Tree of Life, Oxford, 2004, p. 114) Slide #16. Universal tree of life, depicting (arrow) the origin of the mitochondrial symbiosis and suggesting the existence of many extinct or still undiscovered prokaryotic clades. Slide #17. Phylogeny of all known life on Earth Solid bars connote considerable molecular data input (S. L. Baldauf et al., in J. Cracraft and M. J. Donoghue, eds., Assembling the Tree of Life, Oxford, 2004, p. 45)
