Recently, molecular analyses revealed that African and Eurasian golden jackals are distinct species. This finding suggests re‐investigation of the phylogenetic relationships and taxonomy of other African members of the Canidae. Here, we provide a study on the phylogenetic relationship between populations of African jackals Lupulella mesomelas and L. adusta inferred from 962 bp of the mitochondrial cytochrome b (cytb) gene. As expected from its disjunct distribution, with one population in… 
A young age of subspecific divergence in the desert locust, Schistocerca gregaria
TLDR
It is found that the evolutionary processes that have shaped the present geographical distribution of the species in two disjoint northern and southern regions of Africa were recent, dating back 2.6Ky (90% CI: 0.9 – 6.6 Ky).
A young age of subspecific divergence in the desert locust inferred by ABC random forest
TLDR
Full potential of the ABC‐RF approach including prior knowledge on microsatellite genetic markers is shown to decipher the evolutionary history of the African arid‐adapted pest locust, Schistocerca gregaria, with support for a southern colonization of Africa, from a low number of founders of northern origin, dating back 2.6 Ky.
Morphometric analysis of skull shape reveals unprecedented diversity of African Canidae
TLDR
The results depict the absence of morphological overlap between L. m.
Original data for "Chapuis et al., 2020. A young age of subspecific divergence in the desert locust Schistocerca gregaria inferred by ABC Random Forest."
Dating population divergence within species from molecular data and relating such dating to climatic and biogeographic changes is not trivial. Yet it can help formulating evolutionary hypotheses
Phylogeny of the Caninae (Carnivora): Combining morphology, behaviour, genes and fossils
TLDR
It is concluded that macroevolutionary and palaeoecological analyses of the extinct and extant Caninae were to some extent compromised by the phylogenies used.
High-quality carnivoran genomes from roadkill samples enable comparative species delineation in aardwolf and bat-eared fox
TLDR
It is shown that the two subspecies of aardwolf might warrant species status by comparing their genome-wide genetic differentiation to pairs of well-defined species across Carnivora with a new Genetic Differentiation index (GDI) based on only a few resequenced individuals.
High-quality carnivore genomes from roadkill samples enable species delimitation in aardwolf and bat-eared fox
TLDR
Using roadkill samples to sequence reference genomes and study the genomic diversity of the bat-eared fox and the aardwolf, a well resolved genome-scale phylogeny for Carnivora is obtained with evidence for incomplete lineage sorting among the three main arctoid lineages.
Eucyon khoikhoi sp. nov. (Carnivora: Canidae) from Langebaanweg ‘E’ Quarry (early Pliocene, South Africa): the most complete African canini from the Mio-Pliocene
A new medium-sized canid, Eucyon khoikhoi sp. nov., is described from the early Pliocene site of Langebaanweg ‘E’ Quarry (South Africa). It possesses a robust dentition with large upper- and
Selection and Constraints in the Ecomorphological Adaptive Evolution of the Skull of Living Canidae (Carnivora, Mammalia)
TLDR
The results obtained here show that microevolutionary constraints may have played a role in shaping macroevolutionARY patterns of morphological evolution, and it is confirmed that the evolution of cranial morphology was largely adaptive and molded by changes in diet composition.
An annotated checklist of mammals of Kenya
TLDR
An up-to-date annotated checklist of all mammals recorded from Kenya is developed, expecting the number of species to increase with additional surveys and as the taxonomic status of small mammals becomes better understood.

Genome-wide Evidence Reveals that African and Eurasian Golden Jackals Are Distinct Species
TLDR
Using morphologic data, a striking morphologic similarity between East African and Eurasian golden jackals is demonstrated, suggesting parallelism, which may have misled taxonomists and likely reflects uniquely intense interspecific competition in the East African carnivore guild.

TLDR
The large sequence divergence observed among these mtDNA genotypes suggests there should be many more genotypes of intermediate sequence divergence if they had evolved in sympatry, and the results are difficult to reconcile with ideas of a constant molecular clock based on random fixation of selectively neutral or nearly neutral mtDNA sequence mutations.
The evolution of South American endemic canids: a history of rapid diversification and morphological parallelism
TLDR
It is estimated that the most recent common ancestor of South American canids lived around 4 Ma, whereas all other splits within the clade occurred after the rise of the Panamanian land bridge, and a concatenated morphological and molecular analysis put some extinct canid species well within the South American radiation.
Shape Divergence Associated with Size Convergence in Sympatric East African Jackals
TLDR
The recent insinuation of golden jackals into the East African fauna has resulted in character divergence and probable niche compression of blackbacked jackals as evidenced by ad- aptations for increased carnivory, reduced sexual dimorphism, and reduced variability.
Nuclear versus mitochondrial DNA: evidence for hybridization in colobine monkeys
TLDR
This study provides the most comprehensive view on colobine evolution to date and emphasizes that analyses of various molecular markers, such as mobile elements and sequence data from multiple loci, are crucial to better understand evolutionary relationships and to trace hybridization events.
A molecular phylogeny of the Canidae based on six nuclear loci.
TLDR
Phylogenetic analysis with a data set combining the six nuclear loci using MP, ML, and Bayesian approaches produced a more resolved tree that agreed with previously published mitochondrial trees in finding three well-defined clades, including the red fox-like canids, the South American foxes, and the wolf- like canids.
Molecular systematics of the Canidae.
TLDR
A combined analysis of the mtDNA data and published morphological data provides unexpected support for a monophyletic South American canidae clade, although the homogeneity partition tests indicate significant heterogeneity between the two data sets.
Comparative phylogeography of African savannah ungulates 1
TLDR
Data from across taxa reveal distinct regional lineages, which reflect the survival and divergence of populations in isolated savannah refugia during the climatic oscillations of the Pleistocene, and suggest a stable, long‐standing savannah refuge in the south.
A genome-wide perspective on the evolutionary history of enigmatic wolf-like canids.
TLDR
It is found that these enigmatic canids are highly admixed varieties derived from gray wolves and coyotes, respectively, and divergent genomic history suggests that they do not have a shared recent ancestry as proposed by previous researchers.
Allozyme Divergence Within the Canidae
TLDR
The results suggest that the blade-like trenchant heel on the carnassial tooth has evolved indepen- dently at least twice within the Canidae, and several distinct genetic stocks appear to have led to the extant South American canids.
