Human brains are exceptionally large, support distinctive cognitive processes, and evolved
by natural selection to mediate adaptive behavior. Comparative biology situates the human …

Trait databases have become important resources for large-scale comparative studies in
ecology and evolution. Here we introduce the AnimalTraits database, a curated database of …

Variation in spatial complexity and foraging requirements between habitats can impose
different cognitive demands on animals that may influence brain size. However, the …

Ecomorphological studies evaluating the impact of environmental and biological factors on
the brain have so far focused on morphology or size measurements, and the ecological …

Complex evolutionary dynamics have produced extensive variation in brain anatomy in the
animal world. In guppies, Poecilia reticulata, brain size and anatomy have been extensively …

Brain region size generally scales allometrically with brain size, but mosaic shifts in brain
region size independent of brain size have been found in several lineages and may be …

Brains, and the distinct regions that make up brains, vary widely in size across vertebrates
[1, 2]. Two prominent hypotheses have been proposed to explain brain region scaling …

How do large and unique brains evolve? Historically, comparative neuroanatomical studies
have attributed the evolutionary genesis of highly encephalized brains to deviations along …

The usage of telomere length (TL) in blood as a proxy for the TL of other tissues relies on the
assumption that telomere dynamics across all tissues are similar. However, telomere attrition …

Understanding the origins of the vertebrate brain is fundamental for uncovering evolutionary
patterns in neuroanatomy. Regarding extinct species, the anatomy of the brain and other soft …
