“…There is also some disagreement about the relation between Chiroptera and Ferungulata as well as the branch order within the latter clade Nishihara et al, 2006;Nery et al, 2012), but analyses of retroposed elements (Kriegs et al, 2006) and phylogenomic data (Hou et al, 2009) support the configuration on which our analysis is based. Some character transformations occur in the common ancestor of Ferungulata and Chiroptera and our interpretation would not be affected by a difference in branch order.…”

Molecular phylogenetics has made a substantial contribution to our understanding of the relationships between mammalian orders and has generated trees that can be used to examine the evolution of anatomical and physiological traits. We here summarize findings on fetal membranes and placentation in Ferungulata, a clade comprising carnivores, pangolins, and even-and odd-toed ungulates. Their early ontogeny shows several conserved traits such as superficial attachment of the blastocyst, amnion formation by folding, a large allantoic sac and a temporary yolk sac placenta. In contrast, several characters of the chorioallantoic placenta are derived, including the diffuse and cotyledonary placental types in ungulates and zonary placenta in carnivores, specializations of the interhaemal barrier, the presence of areolae or haemophagous regions and lack of stromal decidual cells. Ungulates produce large amounts of placental proteins including placental lactogens and pregnancy-associated glycoproteins. Evolutionary innovations of the placental system may contribute to the high diversity of lifestyles within Ferungulata and be linked to the evolution of highly precocial offspring in ungulates.

“…Recently, Nery et al (2012) choose 3 733 orthologous genes (~50 Mb) obtained from available genome sequences of five orders, namely Eulipotyphla, Chiroptera, Carnivora, Cetartiodactyla, and Perissodactyla. They obtained a Laurasiatheria phylogeny of (Eulipotyphla, ((Chiroptera, Cetartiodactyla), (Perissodactyla, Carnivora))) with high supports ( Figure 1P, Table 1).…”

“…The lack of Pholidota genome sequences in those studies may be one of the reasons causing inconsistent phylogenetic relationships (Bashir et al, 2005;Dos Reis et al, 2012;Hallström et al, 2011;Hou et al, 2009;McCormack et al, 2012;Nery et al, 2012;Nishihara et al, 2006;Prasad et al, 2008;Romiguier et al, 2010;Song et al, 2012), given that tree topology of phylogenetic trees can be biased by sampling errors, leading to an unreliable and unstable estimation. In addition, we note that previous understanding of Laurasiatheria phylogeny largely depended on the analyses of coding DNA sequences, with only a few studies concerning other characters.…”

“…So, attempts to clarify relationships among the six Laurasiatheria orders from a variety of studies have encountered serious challenges due to the rapid evolutionary radiations and recent speciation events. Although there has been a general consensus regarding the earliest divergence of the order Eulipotyphla (Dos Reis et al, 2012;Hallström et al, 2011;Lin et al, 2002;Murphy et al, 2001a, b;Nery et al, 2012;Nishihara et al, 2006;Romiguier et al, 2010;Song et al, 2012;Wildman et al, 2006;Zhou et al, 2011a, b), conflicting phylogenetic hypotheses exist for the other orders that evolved subsequently (Figure 1). In this article, we review the higher-level (inter-ordinal) phylogenies of Laurasiatheria based on previous cytogenetic, morphological and molecular data, and discuss the controversies of its phylogenetic relationship.…”

Laurasiatheria is one of the richest and most diverse superorders of placental mammals. Because this group had a rapid evolutionary radiation, the phylogenetic relationships among the six orders of Laurasiatheria remain a subject of heated debate and several issues related to its phylogeny remain open. Reconstructing the true phylogenetic relationships of Laurasiatheria is a significant case study in evolutionary biology due to the diversity of this suborder and such research will have significant implications for biodiversity conservation. We review the higher-level (inter-ordinal) phylogenies of Laurasiatheria based on previous cytogenetic, morphological and molecular data, and discuss the controversies of its phylogenetic relationship. This review aims to outline future researches on Laurasiatheria phylogeny and adaptive evolution.

Comparative morphology of gigantopyramidal neurons in primary motor cortex across mammals

Gigantopyramidal neurons, referred to as Betz cells in primates, are characterized by large somata and extensive basilar dendrites. Although there have been morphological descriptions and drawings of gigantopyramidal neurons in a limited number of species, quantitative investigations have typically been limited to measures of soma size. The current study thus employed two separate analytical approaches: a morphological investigation using the Golgi technique to provide qualitative and quantitative somatodendritic measures of gigantopyramidal neurons across 19 mammalian species from 7 orders; and unbiased stereology to compare the soma volume of layer V pyramidal and gigantopyramidal neurons in primary motor cortex between 11 carnivore and 9 primate species. Of the 617 neurons traced in the morphological analysis, 181 were gigantopyramidal neurons, with deep (primarily layer V) pyramidal (n = 203) and superficial (primarily layer III) pyramidal (n = 233) neurons quantified for comparative purposes. Qualitatively, dendritic morphology varied considerably across species, with some (sub)orders (e.g., artiodactyls, perissodactyls, feliforms) exhibiting bifurcating, V-shaped apical dendrites. Basilar dendrites exhibited idiosyncratic geometry across and within taxonomic groups. Quantitatively, most dendritic measures were significantly greater in gigantopyramidal neurons than in superficial and deep pyramidal neurons. Cluster analyses revealed that most taxonomic groups could be discriminated based on somatodendritic morphology for both superficial and gigantopyramidal neurons. Finally, in agreement with Brodmann, gigantopyramidal neurons in both the morphological and stereological analyses were larger in feliforms (especially in the Panthera species) than in other (sub)orders, possibly due to specializations in muscle fiber composition and musculoskeletal systems.
