It is demonstrated that phenotypic integration can produce both more and less disparate organisms than would be expected under random walk models by repartitioning variance in preferred directions, and that this effect can also be expected to favour homoplasy and convergent evolution.
Cranial Modularity Shifts during Mammalian Evolution

It is demonstrated that cranial modularity is generally conserved in the evolution of therian mammals but differs between therians and monotremes, the two extant subclasses of Mammalia.

MORPHOLOGICAL INTEGRATION IN THE CARNIVORAN SKULL

Analysis of cranial morphological integration in 30 species from the mammalian order Carnivora, spanning eight extant families and a wide range of ecological and morphological diversity, supports the proposition that evolutionary history is correlated with cranial integration across large clades, although in some smaller clades diet also exerts significant influence on the correlated evolution of traits.
Marine Vertebrates from the ‘Middle’ Cretaceous (Early Cenomanian) of South India

ABSTRACT Vertebrate fossils have been known from South India's Cauvery Basin since the 1840s, but records of marine vertebrates from the late Albian to Turonian Karai Formation have been limited to…
The Influence of Modularity on Cranial Morphological Disparity in Carnivora and Primates (Mammalia)
Within Primates and Carnivora, there was some support for the hypothesis that integration of traits within cranial modules limits morphological evolution, presumably by limiting the variation of individual traits.

This unique fossil assemblage, recovered from middle Miocene deposits of northeastern Peru, greatly increases the known diversity of Cenozoic tropical–equatorial arthropods and microorganisms and provides insights into the biogeography and evolutionary history of modern Neotropical biota.
ISOTOPIC RECORDS FROM EARLY WHALES AND SEA COWS: CONTRASTING PATTERNS OF ECOLOGICAL TRANSITION
Analysis of stable-isotope composition of tooth enamel from several early members of each group to reconstruct the dietary, foraging, and habitat preferences of basal taxa confirms that all of these early forms were primarily aquatic.
Brain size, life history, and metabolism at the marsupial/placental dichotomy

- 7 September 2010
This work provides a direct quantitative comparison of brain size evolution in marsupials and placentals, and suggests that a positive BMR–brain size correlation is a placental trait related to the intimate physiological contact between mother and offspring during gestation.
EMMLi: A maximum likelihood approach to the analysis of modularity
A maximum likelihood approach that takes into account model parameterization is presented, allowing for the direct comparison of models with different parameterizations, providing an important tool for the analysis of modularity across diverse systems.
