Anatomically modern Carboniferous harvestmen demonstrate early cladogenesis and stasis in Opiliones
(Springer Nature, 2011)Harvestmen, the third most-diverse arachnid order, are an ancient group found on all continental landmasses, except Antarctica. However, a terrestrial mode of life and leathery, poorly mineralized exoskeleton makes ... -
Biology of tiny animals: three new species of minute salamanders (Plethodontidae: Thorius) from Oaxaca, Mexico
(PeerJ Inc., 2016)We describe three new species of minute salamanders, genus Thorius, from the Sierra Madre del Sur of Oaxaca, Mexico. Until now only a single species, T. minutissimus, has been reported from this region, although molecular ... -
Collaboration encourages equal sharing in children but not in chimpanzees
(Nature Publishing Group, 2011)Humans actively share resources with one another to a much greater degree than do other great apes, and much human sharing is governed by social norms of fairness and equity. When in receipt of a windfall of resources, ... -
FishFace: interactive atlas of zebrafish craniofacial development at cellular resolution
(BioMed Central, 2013)Background: The vertebrate craniofacial skeleton may exhibit anatomical complexity and diversity, but its genesis and evolution can be understood through careful dissection of developmental programs at cellular resolution. ... -
How comparative psychology can shed light on human evolution: Response to Beran et al.’s discussion of “Cognitive capacities for cooking in chimpanzees”
(Springer Nature, 2016)We recently reported a study (Warneken & Rosati Proceedings of the Royal Society B, 282, 20150229, 2015) examining whether chimpanzees possess several cognitive capacities that are critical to engage in cooking. In a ... -
Inclusive fitness theory and eusociality
(Nature Publishing Group, 2011)Nowak et al. argue that inclusive fitness theory has been of little value in explaining the natural world, and that it has led to negligible progress in explaining the evolution of eusociality. However, we believe that ... -
Insights into the evolution of Darwin’s finches from comparative analysis of the Geospiza magnirostris genome sequence
(BioMed Central, 2013)Background: A classical example of repeated speciation coupled with ecological diversification is the evolution of 14 closely related species of Darwin’s (Galápagos) finches (Thraupidae, Passeriformes). Their adaptive ... -
Melting Lizards and Crying Mailboxes: Children's Preferential Recall of Minimally Counterintuitive Concepts
(Wiley-Blackwell, 2013)Previous research with adults suggests that a catalog of minimally counterintuitive concepts, which underlies supernatural or religious concepts, may constitute a cognitive optimum and is therefore cognitively encoded and ... -
Morphospaces and Databases: Diatom Diversification through Time
(Springer Science + Business Media, 2015)The diversity of diatom form inspired Art Nouveau designers, an interest renewed by recent advances in biomimetic design. The fossil record provides two windows on the diversification history of diatoms: taxonomic diversity ... -
Notch/Delta signalling is not required for segment generation in the basally branching insect Gryllus bimaculatus
(The Company of Biologists, 2011)Arthropods and vertebrates display a segmental body organisation along all or part of the anterior-posterior axis. Whether this reflects a shared, ancestral developmental genetic mechanism for segmentation is uncertain. ... -
Practical Applications of Cosmology to Human Society
(Scientific Research Publishing, Inc,, 2014)Complex systems throughout Nature display structures and functions that are built and maintained, at least in part, by optimal energies flowing through them—not specific, ideal values, rather ranges in energy rate density ... -
Protistan Skeletons: A Geologic History of Evolution and Constraint
(Springer Science + Business Media, 2015)The tests and scales formed by protists may be the epitome of lightweight bioconstructions in nature. Skeletal biomineralization is widespread among eukaryotes, but both predominant mineralogy and stratigraphic history ... -
Recency, Consistent Learning, and Nash Equilibrium
(National Academy of Sciences, 2014)We examine the long-term implication of two models of learning with recency bias: recursive weights and limited memory. We show that both models generate similar beliefs and that both have a weighted universal consistency ... -
Resolving the evolutionary relationships of molluscs with phylogenomic tools
(Nature Publishing Group, 2011)Molluscs (snails, octopuses, clams and their relatives) have a great disparity of body plans and, among the animals, only arthropods surpass them in species number. This diversity has made Mollusca one of the best-studied ... -
Response to vocal music in Angelman syndrome contrasts with Prader-Willi syndrome
(Center for Open Science, 2018-08-13)Parent-offspring conflict, or the conflict over resources between parents and their children due to differences in genetic relatedness, is the biological foundation for a variety of psychological phenomena, including sibling ... -
A system for the continuous directed evolution of biomolecules
(Nature Publishing Group, 2011)Laboratory evolution has generated many biomolecules with desired properties, but a single round of mutation, gene expression, screening or selection, and replication typically requires days or longer with frequent human ... -
Uncovering the Neoproterozoic Carbon Cycle
(Nature Publishing Group, 2012)Interpretations of major climatic and biological events in Earth history are, in large part, derived from the stable carbon isotope records of carbonate rocks and sedimentary organic matter1,2. Neoproterozoic carbonate ...
