Functional morphological integration related to feeding biomechanics in the hominine skull
Body size and allometric variation in facial shape in children
OBJECTIVES: Morphological integration, or the tendency for covariation, is commonly seen in complex traits such as the human face. The effects of growth on shape, or allometry, represent a ubiquitous but poorly understood axis of integration. We address the question of to what extent age and measures of size converge on a single pattern of allometry for human facial shape. METHODS: Our study is based on two large cross-sectional cohorts of childr…
Genes, development, and evolvability in primate evolution
Development is the process whereby a fertilized cell becomes a mature individual. In metazoans, this complex process involves the differentiation of somatic cells into committed cell and tissue types; the organization and migration of cells, tissues, and anatomical structures relative to one another; and growth. Development matters to evolution in two ways. First, development carries out heritable genetic instructions contained in zygotes to prod…
Response to Almécija and Alba (2014) – On manual proportions in Australopithecus afarensis
Reassessing manual proportions in Australopithecus afarensis
Previous analyses of hand morphology in Australopithecus afarensis have concluded that this taxon had modern human‐like manual proportions, with relatively long thumbs and short fingers. These conclusions are based on the A.L.333 composite fossil assemblage from Hadar, Ethiopia, and are premised on the ability to assign phalanges to a single individual, and to the correct side and digit. Neither assignment is secure, however, given the taphonomy …
A resampling approach and implications for estimating the phalangeal index from unassociated hand bones in fossil primates
Primate fossil assemblages often have metacarpals and phalanges from which functional/behavioral interpretations may be inferred. For example, intrinsic hand proportions can indicate hand function and substrate use. But, estimates of intrinsic hand proportions from unassociated hand elements can be imperfect due to digit misattribution. Although isolated metacarpals can be identified to a specific digit, phalanges are difficult to assign to a spe…
