1. A comparison of catarrhine genetic distances with pelvic and cranial morphology: Implications for determining hominin phylogeny.

    Journal of Human Evolution 77:179 (2014) PMID 25439629

    Inferring the evolutionary history of the hominins is necessarily reliant on comparative analyses of fossilized skeletal anatomy. However, the reliability of different primate skeletal regions for recovering phylogenetic relationships is currently poorly understood. Historically, postcranial var...

  3. From cultural traditions to cumulative culture: parameterizing the differences between human and nonhuman culture.

    Journal of Theoretical Biology 359:29 (2014) PMID 24928150

    Diverse species exhibit cultural traditions, i.e. population-specific profiles of socially learned traits, from songbird dialects to primate tool-use behaviours. However, only humans appear to possess cumulative culture, in which cultural traits increase in complexity over successive generations...
  4. The role of raw material differences in stone tool shape variation: an experimental assessment

    Journal of Archaeological Science 49:472 (2014)

    Lithic raw material differences are widely assumed to be a major determining factor of differences in stone tool morphology seen across archaeological sites, but the security of this assumption remains largely untested. Two different sets of raw material properties are thought to influ...

  7. The interaction of neutral evolutionary processes with climatically-driven adaptive changes in the 3D shape of the human os coxae.

    Journal of Human Evolution 73:64 (2014) PMID 24935167

    Differences in the breadth of the pelvis among modern human populations and among extinct hominin species have often been interpreted in the light of thermoregulatory adaptation, whereby a larger pelvic girdle would help preserve body temperature in cold environments while a narrower pelvis woul...
  8. Dynamics of cultural transmission in Native Americans of the high Great Plains.

    PLoS ONE 9(11):e112244 (2014) PMID 25372277 PMCID PMC4221622

    Culture is a phenomenon shared by all humans. Attempts to understand how dynamic factors affect the origin and distribution of cultural elements are, therefore, of interest to all humanity. As case studies go, understanding the distribution of cultural elements in Native American communities dur...

  10. Considering the role of time budgets on copy-error rates in material culture traditions: an experimental assessment.

    PLoS ONE 9(5):e97157 (2014) PMID 24809848 PMCID PMC4014615

    Ethnographic research highlights that there are constraints placed on the time available to produce cultural artefacts in differing circumstances. Given that copying error, or cultural 'mutation', can have important implications for the evolutionary processes involved in material culture change,...

  12. Are bigger flakes always better? An experimental assessment of flake size variation on cutting efficiency and loading

    Journal of Archaeological Science 41:140 (2014)

    Previous studies have indicated that the cutting efficiency of flake tools increases with increased tool size. Here, we undertook to examine the relationship between flake size and efficiency parameters using a larger and more variable flake dataset than used in previous analyses. Our ...

  15. Levallois economics: an examination of ‘waste’ production in experimentally produced Levallois reduction sequences

    Journal of Archaeological Science 40(5):2384 (2013)

    Mathematical modelling has suggested that Levallois core morphology represents a reduction strategy driven by economic considerations; particularly the minimization of ‘waste’ while aiming to maximize cutting edge length of flakes obtained from cores of a given size. Such models are el...
  16. Understanding the comparative catarrhine context of human pelvic form: A 3D geometric morphometric analysis

    Journal of Human Evolution 64(4):300 (2013)

    Comparative studies of catarrhine pelvic morphology in an evolutionary framework play an important role in paleoanthropology, especially since this is the context from which human bipedalism eventually arose. Given the abundance of potentially confounding evolutionary and mechanical fa...

  18. A 3D morphometric analysis of surface geometry in Levallois cores: patterns of stability and variability across regions and their implications

    Journal of Archaeological Science 40(3):1508 (2013)

    Levallois cores and products were manufactured by hominin populations distributed across wide regions of Africa and Eurasia. Levallois technology remains an important focus for research in Palaeolithic archaeology, yet quantitative morphological comparisons of Levallois core morphology...
  19. Global geometric morphometric analyses of the human pelvis reveal substantial neutral population history effects, even across sexes.

    PLoS ONE 8(2):e55909 (2013) PMID 23409086 PMCID PMC3567032

    Recent applications of population genetic models to human craniodental traits have revealed a strong neutral component to patterns of global variation. However, little work has been undertaken to determine whether neutral processes might also be influencing the postcranium, perhaps due to substa...
