Article Reference Complex geographical variation patterns in Tropheus duboisi Marlier, 1959 (Perciformes, Cichlidae) from Lake Tanganyika
Intra-specific morphological variation in the cichlid Tropheus duboisi from 10 localities over its entire known distribution area along the central eastern and northern shore of Lake Tanganyika was investigated. This revealed significant differences between various populations that are geographically isolated. These morphological observations only partially correspond to the results of a haplotype network, based on mtDNA. In addition, a difference in the timing of the onset of the adult colour pattern was discovered for one isolated population. The occurrence of morphological intra-specific differentiation is discussed with respect to the basal position of T. duboisi within Tropheus as well as to the presumed morphological stasis of the genus.

Article Reference The evolutionary history of Neanderthal and Denisovan Y chromosomes
The genomes of archaic hominins have been sequenced and compared with that of modern humans. However, most archaic individuals with high-quality sequences available have been female. Petr et al. performed targeted sequencing of the paternally inherited Y chromosomes from three Neanderthals and two Denisovans (see the Perspective by Schierup). Comparisons with available archaic and diverse modern human Y chromosomes indicated that, similar to the maternally inherited mitochondria, the human and Neanderthal Y chromosomes were more closely related to each other compared with the Denisovan Y chromosome. This result supports the conclusion that interbreeding between early humans and Neanderthals and selection replaced the more ancient Denisovian-like Y chromosome and mitochondria in Neanderthals.Science, this issue p. 1653; see also p. 1565Ancient DNA has provided new insights into many aspects of human history. However, we lack comprehensive studies of the Y chromosomes of Denisovans and Neanderthals because the majority of specimens that have been sequenced to sufficient coverage are female. Sequencing Y chromosomes from two Denisovans and three Neanderthals shows that the Y chromosomes of Denisovans split around 700 thousand years ago from a lineage shared by Neanderthals and modern human Y chromosomes, which diverged from each other around 370 thousand years ago. The phylogenetic relationships of archaic and modern human Y chromosomes differ from the population relationships inferred from the autosomal genomes and mirror mitochondrial DNA phylogenies, indicating replacement of both the mitochondrial and Y chromosomal gene pools in late Neanderthals. This replacement is plausible if the low effective population size of Neanderthals resulted in an increased genetic load in Neanderthals relative to modern humans.

Article Reference A secondary mandibular condylar articulation and collateral effects on a Late Neolithic mandible from Bois Madame rockshelter in Arbre, Belgium
A Neolithic Belgian mandible from Bois Madame rockshelter in Arbre presents an asymmetrical morphology resulting from a secondary, or false, articulation of the right mandibular condyle. The pathological articulation produced enlarged masseter, medial pterygoid and mylohyoid musculature on the right side as well as a flattening of the right incisal alveolus curvature. The secondary condylar articulation did not lead to pronounced asymmetry of attrition on the antimeres of the dental arcade. This is the most complete mandible from this Late Neolithic collective burial dating to the beginning of the Bronze Age circa 4000 years BP. It is possible that a fall or blow to the mental symphysis during early adolescence could have resulted in the partial intrusion of the mandibular condyle into the articulation disc of the temporomandibular joint capsule. When the affected condyle healed, a secondary, but serviceable articulation developed, producing unique stresses on the involved muscular tissue and ultimately resulted in an asymmetry of mandibular form.
