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.

Inproceedings Reference RESPONSE project: Reactive transport of point source contamination in soils and groundwater
The RESPONSE project aims at improving the use of coupled reactive transport models to simulate the fate of inorganic and organic contaminants within environments, characterised by a fluctuating shallow groundwater table – inducing strong hydraulic, physico-chemical and redox gradients. Three case studies were selected based on the presence of inorganic and/or organic contamination. Two sites are cemeteries where groundwater pollution by herbicides (2,6-dichlorobenzamide (BAM) – a persistent metabolite of herbicide dichlobenil) was detected. Top soil and groundwater samples were collected and the BAM degradation and mineralization potential of soil microbiota is tested in the laboratory. It is hypothesized that BAM degradation is strongly affected by DOC quality (measured through specific UV absorbance) and quantity. RESPONSE will investigate whether predictions of dichlobenil and BAM migration in soils and groundwater can be improved by taking into account DOC quality/quantity.The third site is a former municipal landfill, where redox zonation and contamination by As is observed. This site is primarily used to study the level of hydrogeological and geochemical detail needed to predict the migration of pollutants in a satisfactory way. This hypothesis is tested by comparing predictions using site specific measured parameters (soil and subsoil hydraulic parameters, in-situ groundwater flow characterization, etc.) with predictions using parameters inferred from existing hydrological/ geochemical data available in data bases. Moreover, an integrated tool is developed to simulate water flow and reactive solute transport in the subsurface focusing on the water table interface. This is achieved by loosely coupling the existing HYDRUS, MODFLOW, MT3D-USGS and PHREEQC codes at the lowest level and adding functionalities for the transfer of solute concentrations. The HYDRUS package for MODFLOW (Seo et al., 2007) has been updated and PHREEQC functionalities are coupled to both the unsaturated zone (based on HPx software; Jacques et al., 2018) and the saturated zone.
