Modeling the origins of mammalian sociality: moderate evidence for matrilineal signatures in mouse lemur vocalizations [PDF]
, 2014 Introduction: Maternal kin selection is a driving force in the evolution of mammalian social complexity and it requires that kin are distinctive from nonkin.

Incongruence between genetic and morphological diversity in
BMC Evolutionary Biology, 2006 Background The past decade has seen a remarkable increase in the number of recognized mouse lemur species (genus Microcebus). As recently as 1994, only two species of mouse lemur were recognized according to the rules of zoological nomenclature.

Nasal Fossa of Mouse and Dwarf Lemurs (Primates, Cheirogaleidae) [PDF]
The Anatomical Record, 2008 AbstractDimensions of the external midface in mammals are sometimes related to olfactory abilities (e.g., “olfactory snouts” of strepsirrhine primates). This association hinges on the largely unexplored relationship between the protruding midface and internal topography of the nasal fossae.

Rate variation during molecular evolution: creationism and the cytochrome c molecular clock [PDF]
, 2017 Molecular clocks based upon amino acid sequences in proteins have played a major role in the clarification of evolutionary phylogenies. Creationist criticisms of these methods sometimes rely upon data that might initially seem to be paradoxical.

BMC Ecology, 2012 Background Studies of host-parasite interactions have the potential to provide insights into the ecology of both organisms involved. We monitored the movement of sucking lice (Lemurpediculus verruculosus), parasites that require direct host-host contact ...

Captive Dwarf and Mouse Lemurs Have Variable Fur Growth [PDF]
Animals, 2020 Researchers typically assume constant fur and hair growth for primates, but the few studies that have investigated growth explicitly suggest this may not be the case. Instead, growth may vary considerably among individuals and across seasons. One might expect this variability to be most pronounced for species that have seasonally variable activity ...

An Adaptive Threshold in Mammalian Neocortical Evolution
, 2013 Expansion of the neocortex is a hallmark of human evolution. However, it remains an open question what adaptive mechanisms facilitated its expansion.

The Anatomical Record, EarlyView.Abstract Last year, we challenged the view that large‐bodied theropod dinosaurs such as Tyrannosaurus rex resembled primates in cognition and behavior, a proposition made by Herculano‐Houzel in 2023. More recently, Jensen et al. have criticized our work on this topic, raising methodological and conceptual issues.
