Dear morphometricians,
I like to draw your attention to some new papers (all are open access): Grunstra NDS, Bartsch S, Le Maître A, Mitteroecker P (in press) Detecting Phylogenetic Signal and Adaptation in Papionin Cranial Shape by Decomposing Variation at Different Spatial Scales. *Systematic Biology* https://doi.org/10.1093/sysbio/syaa093 Here, we show how to decompose shape variation into shape components that are likely to be functionally relevant and components that capture "constructional details," such as the contributions of different bones to overall shape. These latter components are largely hidden from selection and thus tend to evolve more neutrally than functional shape components. In a sample of papionin monkeys, we show that these components of cranial shape indeed lead to a more reliable phylogenetic reconstruction than overall cranial shape. Mitteroecker P, Stansfield E (2021) A model of developmental canalization, applied to human cranial form. *PLOS Computational Biology* 17(2): e1008381 https://doi.org/10.1371/journal.pcbi.1008381 In this paper we introduce a statistical model of canalized development (sensu Waddington) and show how the strength of canalization and the canalized variance can be estimated from longitudinal data, even if the "target trajectories" of individual development are unobserved. We extend this model to multivariate measures and apply it to longitudinal geometric morphometric data on human postnatal craniofacial size and shape as well as to the size of the frontal sinuses. Waltenberger L, Rebay-Salisbury K, Mitteroecker P (in press) Three-dimensional surface scanning methods in osteology: A topographical and geometric morphometric comparison. *American Journal of Physical Anthropology *https://doi.org/10.1002/ajpa.24204 This paper gives an overview and some empirical tests of 3D surface scanning methods, especially photogrammetry, with applications to human pelves.
