During the Pleistocene, South America had several genera and species of large hypercarnivorous canids, which became completely extinct at end this epoch. This paper presents a comprehensive systematic review group (four genera, seven species) based on new cladistic analyses that include genomic information study intraspecific variation in canids. The results generated are discussed context know...

The four extant species of hyenas (Hyaenidae; Carnivora) form a morphologically and ecologically heterogeneous group of feliform carnivorans that are remnants of a formerly diverse group of mammalian predators. They include the aardwolf (Proteles cristatus), a termite-feeding specialist, and three species with a craniodental morphology adapted to cracking the bones of prey and/or carcasses, the...

In response to Quinn (Biol Philos, 2017. 10.1007/s10539-017-9577-z) we identify cladistics to be about natural classifications and their discovery and thereby propose to add an eighth cladistic definition to Quinn's list, namely the systematist who seeks to discover natural classifications, regardless of their affiliation, theoretical or methodological justifications.

Artiopoda was a diverse group of Palaeozoic euarthropods that proliferated in the early Palaeozoic, epitomized by ubiquitous trilobites. Their possible phylogenetic position outside mandibulates and chelicerates offers potential for understanding evolution more detail. However, this opportunity remains unexploited given identification deep-splitting artiopodans to be fully explored. Here, we de...
