It was becoming more arid, the tropical forests were disappearing from the northern latitudes, and there was an increase in seasonality. Research of the Chadronian (37- 33.7mya) in the Great Plains region of North America has documented the persistence of several mammalian taxa (e.g. primates) that are extinct in other parts of North America. -
The Beaver's Phylogenetic Lineage Illuminated by Retroposon Reads
www.nature.com/scientificreports OPEN The Beaver’s Phylogenetic Lineage Illuminated by Retroposon Reads Liliya Doronina1,*, Andreas Matzke1,*, Gennady Churakov1,2, Monika Stoll3, Andreas Huge3 & Jürgen Schmitz1 Received: 13 October 2016 Solving problematic phylogenetic relationships often requires high quality genome data. However, Accepted: 25 January 2017 for many organisms such data are still not available. Among rodents, the phylogenetic position of the Published: 03 March 2017 beaver has always attracted special interest. The arrangement of the beaver’s masseter (jaw-closer) muscle once suggested a strong affinity to some sciurid rodents (e.g., squirrels), placing them in the Sciuromorpha suborder. Modern molecular data, however, suggested a closer relationship of beaver to the representatives of the mouse-related clade, but significant data from virtually homoplasy- free markers (for example retroposon insertions) for the exact position of the beaver have not been available. We derived a gross genome assembly from deposited genomic Illumina paired-end reads and extracted thousands of potential phylogenetically informative retroposon markers using the new bioinformatics coordinate extractor fastCOEX, enabling us to evaluate different hypotheses for the phylogenetic position of the beaver. Comparative results provided significant support for a clear relationship between beavers (Castoridae) and kangaroo rat-related species (Geomyoidea) (p < 0.0015, six markers, no conflicting data) within a significantly supported mouse-related clade (including Myodonta, Anomaluromorpha, and Castorimorpha) (p < 0.0015, six markers, no conflicting data). Most of an organism’s phylogenetic history is fossilized in their heritable genomic material. Using data from genome sequencing projects, particularly informative regions of this material can be extracted in sufficient num- bers to resolve the deepest history of speciation. -

The Impact of Locomotion on the Brain Evolution of Squirrels and Close Relatives ✉ Ornella C
ARTICLE https://doi.org/10.1038/s42003-021-01887-8 OPEN The impact of locomotion on the brain evolution of squirrels and close relatives ✉ Ornella C. Bertrand 1 , Hans P. Püschel 1, Julia A. Schwab 1, Mary T. Silcox 2 & Stephen L. Brusatte1 How do brain size and proportions relate to ecology and evolutionary history? Here, we use virtual endocasts from 38 extinct and extant rodent species spanning 50+ million years of evolution to assess the impact of locomotion, body mass, and phylogeny on the size of the brain, olfactory bulbs, petrosal lobules, and neocortex. We find that body mass and phylogeny are highly correlated with relative brain and brain component size, and that locomotion strongly influences brain, petrosal lobule, and neocortical sizes. Notably, species living in 1234567890():,; trees have greater relative overall brain, petrosal lobule, and neocortical sizes compared to other locomotor categories, especially fossorial taxa. Across millions of years of Eocene- Recent environmental change, arboreality played a major role in the early evolution of squirrels and closely related aplodontiids, promoting the expansion of the neocortex and petrosal lobules. Fossoriality in aplodontiids had an opposing effect by reducing the need for large brains. 1 School of GeoSciences, University of Edinburgh, Grant Institute, Edinburgh, Scotland, UK. 2 Department of Anthropology, University of Toronto Scarborough, ✉ Toronto, ON, Canada. email: [email protected] COMMUNICATIONS BIOLOGY | (2021) 4:460 | https://doi.org/10.1038/s42003-021-01887-8 | www.nature.com/commsbio 1 ARTICLE COMMUNICATIONS BIOLOGY | https://doi.org/10.1038/s42003-021-01887-8 hat ecological and evolutionary factors affect brain size striking differences between living sciurids and aplodontiids raise in mammals?

Deinogalerix : a Giant Hedgehog from the Miocene
Annali dell’Università di Ferrara ISSN 1824-2707 Museologia Scientifica e Naturalistica Volume 6 (2010) Deinogalerix : a giant hedgehog from the Miocene Boris VILLIER* * Dipartimento di scienze della Terra, Università degli Studi di Torino [email protected] SUPERVISORS: Marco Pavia e Marta Arzarello __________________________________________________________________________________ Abstract During the Miocene the Abruzzo/Apulia region (Italy), isolated from the continent, was the theatre of the evolution of a vertebrate ecosystem in insular context. At the late Miocene the protagonists of this ecosystem called “ Mikrotia fauna ” show a high endemic speciation level with spectacular giant and dwarf species of mammals and birds. Most of the remains of this peculiar fauna are found exclusively in the “Terre rosse” of Gargano, except for the oldest genus: Deinogalerix and Hoplitomeryx , also found at Scontrone. Deinogalerix is one of the most uncommon forms of the “ Mikrotia fauna ”. It’s the largest Erinaceidea ever lived. Deinogalerix was described for the first by Freudenthal (1972) then by Butler (1980). Today the five species yet described are under discussion cause of the high intraspecific variations in an insular evolution context. In this study we valuated the information that could bring the new discoveries of Deinogalerix remains. The work was divided into three main parts: the preparation of the material, the drawing reconstructions and the anatomical description. The most important specimen was the second sub-complet skeleton ever found. We gave the most objective anatomical description for futures comparison with the first skeleton from a different specie. We put the finger on new juvenile features and on the relation between the growth of Deinogalerix and his feeding behaviours. -

We used linear regressions to investigate the relationship between Si and M, and ANCOVA to compare trends among taxonomic and functional groups. Results Si was significantly and negatively related to the mass of the ancestral or mainland population across all mammals and within all orders of extant mammals analysed, and across palaeo-insular (considered separately) mammals as well. Insular body size was significantly smaller for bats and insectivores than for the other orders studied here, but significantly larger for mammals that utilized aquatic prey than for those restricted to terrestrial prey. -
