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 ...

Mosaic evolution in an asymmetrically feathered troodontid dinosaur with transitional features [PDF]
Nature Communications, 2017 Troodontids were theropod dinosaurs closely related to birds. Here, Xu and colleagues describe a new, feathered troodontid species,Jianianhualong tengi, dating from the Lower Cretaceous period in China that provides insight into troodontid mosaic ...

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 ...

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 ...

“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 ...

Mosaic evolution of a learning and memory circuit in Heliconiini butterflies
Current BiologyAbstract A critical function of central neural circuits is to integrate sensory and internal information to cause a behavioural output. Evolution modifies such circuits to generate adaptive change in sensory detection and behaviour, but it remains unclear how selection does so in the context of existing functional and

The earliest dipodomyine heteromyid in North America and the phylogenetic relationships of geomorph rodents [PDF]
PeerJ, 2023 Dipodomyine heteromyids (kangaroo rats and mice) are a diverse group of arid-adapted ricochetal rodents of North America. Here, a new genus and species of a large dipodomyine is reported from early Miocene-aged deposits of the John Day Formation in ...

eLife, 2022 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 related to the evolution of behavioral novelty.
