Objectives Synovial joints in human limbs strike a balance between mobility, stability, and
articular fit, yet little is known about how these conflicting demands pattern intraspecific …

The goal of evolutionary biology is to explain the diversity of the entire sweep of the natural
world; population biology only examines tiny slices of time of a few individuals of single …

Quantitative genetic theory on multivariate character evolution predicts that a population's
response to directional selection is biased towards the major axis of the genetic covariance …

Among Primates, forelimb suspension appears to have evolved in only a handful of clades,
but within a majority of those clades it likely evolved multiple times. The question of parallel …

Observations of phenotypic trait differences between taxa are one fundamental way in which
biologists seek to understand how evolution has driven diversification. However, phenotypic …
