“…Recently, a new Bovidae species – saola ( Pseudoryx nghetinhensis , PNG, 2n = 50) was discovered, living in the forest jungle, which separates Vietnam from Laos [13]. Molecular phylogenetic studies place this species in subfamily Bovinae, tribe Bovini.…”

BackgroundPronghorn (Antilocapridae, 2n = 58) and saola (Bovidae, 2n = 50) are members of Pecora, a highly diversified group of even-toed hoofed mammals. Karyotypes of these species were not involved in chromosome painting studies despite their intriguing phylogenetic positions in Pecora.ResultsTo trace the chromosome evolution during very fast radiation of main families from the common Pecoran ancestor, high-resolution comparative chromosome maps of pronghorn and saola with human (HSA) and dromedary camel (CDR) painting probes were established. The human and dromedary camel painting probes revealed 50 and 64 conserved segments respectively in the pronghorn genome, while 51 and 63 conserved segments respectively in the saola genome. Integrative analysis with published comparative maps showed that inversions in chromosomes homologous to CDR19/35/19 (HSA 10/20/10), CDR12/34/12 (HSA12/22/12/22), CDR10/33/10 (HSA 11) are present in representatives of all five living Pecoran families. The pronghorn karyotype could have formed from a putative 2n = 58 Pecoran ancestral karyotype by one fission and one fusion and that the saola karyotype differs from the presumed 2n = 60 bovid ancestral karyotype (2n = 60) by five fusions.ConclusionThe establishment of high-resolution comparative maps for pronghorn and saola has shed some new insights into the putative ancestral karyotype, chromosomal evolution and phylogenic relationships in Pecora. No cytogenetic signature rearrangements were found that could unite the Antilocapridae with Giraffidae or with any other Pecoran families. Our data on the saola support a separate position of Pseudorigyna subtribe rather than its affinity to either Bovina or Bubalina, but the saola phylogenetic position within Bovidae remains unresolved.

“…Biologists and Paleontologists use cladistics as a method to investigate the common origins, or 'tree' of life (Darwin 1859;Hennig 1965;Hug et al 2016), and how different species are related to one another (e.g. Van Dung et al 1993;Salisbury et al 2006;Říčan et al 2011;Smith et al 2017;Aria & Caron 2017). Historically, the investigation into relationships between different organisms reaches back to Darwin (1859).…”

Jupiter and Saturn each have complex systems of satellites and rings. These satellites can be classified into dynamical groups, implying similar formation scenarios. Recently, a larger number of additional irregular satellites have been discovered around both gas giants that have yet to be classified. The aim of this paper is to examine the relationships between the satellites and rings of the gas giants, using an analytical technique called cladistics. Cladistics is traditionally used to examine relationships between living organisms, the 'tree of life'. In this work, we perform the first cladistical study of objects in a planetary science context. Our method uses the orbital, physical and compositional characteristics of satellites to classify the objects in the Jovian and Saturnian systems. We find that the major relationships between the satellites in the two systems, such as families, as presented in previous studies, are broadly preserved. In addition, based on our analysis of the Jovian system, we identify a new retrograde irregular family, the Iocaste family, and suggest that the Phoebe family of the Saturnian system can be further divided into two subfamilies. We also propose that the Saturnian irregular families be renamed, to be consistent with the convention used in Jovian families. Using cladistics, we are also able to assign the new unclassified irregular satellites into families. Taken together, the results of this

“…Such circumscription is highly undesirable when novel forms may be present (as here): the most dramatic example of this is that numerous picture-based interviews in the Lao range of saola Pseudoryx nghetinhensis failed to reveal the presence of this animal in the years immediately before it was discovered in Vietnam in 1992 (Vu Van Dung et al 1993), whereas verbal discussions using such topics as "please name and describe each species of large animal living round here" would certainly stimulated mention of this remarkably distinctive animal. It is quite possible that, if there are François'-group leaf monkeys in Lao PDR's northern highlands, they will be known by one or more Lao or minority-language names different from any yet recorded, so they cannot predictably be picked up by interviews asking whether each of a list of named (Lao name) species lives in the area.…”
