- The importance of preadapted genomes in the origin of the animal bodyplans and the Cambrian explosionCharles R Marshall
Department of Invertebrate Paleontology, Museum of Comparative Zoology, Harvard University, Cambridge, Massachusetts 02138, USA
Evolution 64:1189-201. 2010..Subsequently, protein-coding genic richness appears to have essentially plateaued. Some genomic evidence suggests that similar stages of genomic evolution may have accompanied the rise of land plants...
- A simple method for bracketing absolute divergence times on molecular phylogenies using multiple fossil calibration pointsCharles R Marshall
Museum of Comparative Zoology, Department of Organismic and Evolutionary Biology, Harvard University, Cambridge, Massachusetts 02138, USA
Am Nat 171:726-42. 2008..The effect of violations of these assumptions is assessed. This method is simple to use and is illustrated with a reanalysis of Near et al.'s turtle data...
- Linking form and function of the fibrous joints in the skull: a new quantification scheme for cranial sutures using the extant fish Polypterus endlicheriiMolly J Markey
Department of Earth and Planetary Sciences, Harvard University, Cambridge, Massachusetts 02138, USA
J Morphol 268:89-102. 2007..Finally, although the sutures of P. endlicherii appear to be significantly less complex than those of mammals, these fish sutures show a similar range of morphologies and perform similar functions as do mammalian sutures...

Proc Natl Acad Sci U S A 107:7365-70. 2010..melpomene and H. erato, rather than being their respective sister species. Estimates of mtDNA divergence suggest a minimum age of 2.8 and 2.1 My for H. erato and H. melpomene, respectively, placing their origins in the late Pliocene...

- Terrestrial-style feeding in a very early aquatic tetrapod is supported by evidence from experimental analysis of suture morphologyMolly J Markey
Department of Earth and Planetary Sciences and Museum of Comparative Zoology, Harvard University, 26 Oxford Street, Cambridge, MA 02138, USA
Proc Natl Acad Sci U S A 104:7134-8. 2007..Thus, our data strongly support the hypothesis that the terrestrial mode of feeding first emerged in aquatic taxa...
- Extinction during evolutionary radiations: reconciling the fossil record with molecular phylogeniesTiago B Quental
Department of Invertebrate Paleontology, Museum of Comparative Zoology, Harvard University, 26 Oxford Street, Cambridge, Massachusetts 02138, USA
Evolution 63:3158-67. 2009..This is important because the fossil record provides more reliable estimates of equilibrium extinction rates than initial speciation rates...
- Dating the origin of the Orchidaceae from a fossil orchid with its pollinatorSantiago R Ramírez
Museum of Comparative Zoology, Harvard University, 26 Oxford St, Cambridge, Massachusetts 02138, USA
Nature 448:1042-5. 2007..These results further support the hypothesis of an ancient origin for Orchidaceae...
- In vivo cranial suture function and suture morphology in the extant fish Polypterus: implications for inferring skull function in living and fossil fishMolly J Markey
Department of Earth and Planetary Sciences, Harvard University, USA
J Exp Biol 209:2085-102. 2006..This is consistent with published correlations of suture form and function in mammals, where interdigitated sutures indicate compression and lack of interdigitation is associated with tension...
- Phanerozoic marine biodiversity dynamics in light of the incompleteness of the fossil recordPeter J Lu
Department of Physics, Jefferson Laboratory, 17 Oxford Street, Harvard University, Cambridge, MA 02138, USA
Proc Natl Acad Sci U S A 103:2736-9. 2006..Thus, although certain individual cases may deviate from the overall pattern, we find that in general the biosphere's response to perturbation is immediate geologically and usually short-lived...
- Phanerozoic trends in the global diversity of marine invertebratesJohn Alroy
National Center for Ecological Analysis and Synthesis, University of California Santa Barbara, 735 State Street, Santa Barbara, CA 93101, USA
Science 321:97-100. 2008..The ratio of global to local richness has changed little, and a latitudinal diversity gradient was present in the early Paleozoic...
- Using the fossil record to estimate the age of the last common ancestor of extant primatesSimon Tavare
Department of Biological Sciences, University of Southern California, Los Angeles, California 90089 1340, USA
Nature 416:726-9. 2002..The approach unites all the available palaeontological methods of timing evolutionary events: the fossil record, extant species and clade diversification models...
