Evidence for Concerted and Mosaic Brain Evolution in Dragon Lizards [PDF]
Brain, Behavior and Evolution, 2017 The brain plays a critical role in a wide variety of functions including behaviour, perception, motor control, and homeostatic maintenance. Each function can undergo different selective pressures over the course of evolution, and as selection acts on the outputs of brain function, it necessarily alters the structure of the brain.

Developmental origins of mosaic evolution in the avian cranium. [PDF]
Proc Natl Acad Sci U S A, 2018 Significance Studies reconstructing morphological evolution have long relied on simple representations of organismal form or on limited sampling of species, hindering a comprehensive understanding of the factors shaping biological diversity.

Mosaic and concerted evolution in the visual system of birds. [PDF]
PLoS ONE, 2014 Two main models have been proposed to explain how the relative size of neural structures varies through evolution. In the mosaic evolution model, individual brain structures vary in size independently of each other, whereas in the concerted evolution ...

The mosaic evolution of Left Dislocation in Xhosa
Stellenbosch Papers in Linguistics Plus, 2016 This paper demonstrates that the status of Clitic LD in Xhosa is a result of the mosaic evolution of Xhosa grammar. It emerges as an accumulation and combination of two more individual, distinct and, at least, initially separated developments and ...

Spatial mosaic evolution of snail defensive traits [PDF]
BMC Evolutionary Biology, 2007 Background Recent models suggest that escalating reciprocal selection among antagonistically interacting species is predicted to occur in areas of higher resource productivity.

“Living fossils” and the mosaic evolution of characters
Frontiers in Ecology and Evolution, 2023 The modern discussion of living fossils turns mostly on the persistence of archaic, or ancestral, traits in extant organisms. Prime examples mentioned by Darwin already—who also coined the term “living fossil”—include the platypus and the extant ...

Systematic determination of the mosaic structure of bacterial genomes: species backbone versus strain-specific loops [PDF]
BMC Bioinformatics, 2005 Background Public databases now contain multitude of complete bacterial genomes, including several genomes of the same species. The available data offers new opportunities to address questions about bacterial genome evolution, a task that requires ...

Mosaic Evolution of the Phosphopantothenate Biosynthesis Pathway in Bacteria and Archaea. [PDF]
Genome Biol Evol, 2021 Abstract Phosphopantothenate is a precursor to synthesis of coenzyme A, a molecule essential to many metabolic pathways. Organisms of the archaeal phyla were shown to utilize a different phosphopantothenate biosynthetic pathway from the eukaryotic and bacterial one.

Mosaic evolution underlies feliform morphological disparity. [PDF]
Proc Biol SciConstraint is a fundamental concept in evolutionary theory. Morphology and ecology both are limited by functional, historical and developmental factors to a subset of the theoretical range species could occupy. Cat-like carnivorans (Feliformia) offer a unique opportunity to investigate phenotypic constraint, as several feliform clades are purported to ...
