Significance The microbiome plays key roles in human health, but little is known about its evolution. We investigate the evolutionary history of African hominid oral by analyzing dental biofilms humans and Neanderthals spanning past 100,000 years comparing them with those chimpanzees, gorillas, howler monkeys. identify 10 core bacterial genera that have been maintained within lineage play biofilm structural roles. However, many remain understudied unnamed. find major taxonomic functional...
The increasing catalogue of high-quality ice-penetrating radar data provides a unique insight in the internal layering architecture Greenland ice sheet. stratigraphy, an indicator past deformation, highlights irregularities flow and reveals large perturbations without obvious links to bedrock shape. In this work, establish new conceptual model for formation process, we analysed at onset Petermann Glacier, North Greenland, created three-dimensional several distinct stratigraphic layers. We...
Abstract Only a few localised ice streams drain most of the from Greenland Ice Sheet. Thus, understanding stream behaviour and its temporal variability is crucially important to predict future sea-level change. The interior trunk 700 km-long North-East Stream (NEGIS) remarkable due lack any clear bedrock channel explain presence. Here, we present 3-dimensional analysis folding advection stratigraphic horizons, which shows that flow shear margins in upper NEGIS were fully developed only ca...
Hominin evolution is characterized by progressive regional differentiation, as well migration waves, leading to anatomically modern humans that are assumed have emerged in Africa and spread over the whole world. Why or whether was source region of what caused their remains subject ongoing debate. We present a spatially explicit, stochastic numerical model includes mutations, demic diffusion, assortative mating waves. Diffusion alone result structured population with relatively homogeneous...
Abstract We present a dataset of reconstructed three-dimensional (3D) englacial stratigraphic horizons in northern Greenland. The data cover four different regions representing key ice-dynamic settings Greenland: (i) the onset Petermann Glacier, (ii) region upstream 79° North Glacier (Nioghalvfjerdsbræ), near Greenland ice divide, (iii) Northeast Ice Stream (NEGIS) and (iv) 700 km wide extending across central divide over entire part In this paper, we promote advantages 3D perspective...
The taxonomic attribution of the 1.55 million year old young adult fossil calvaria KNM-ER 42700 from Ileret, Kenya, is subject to ongoing controversy. It has been attributed H. erectus based on comparative description and linear measurements. However, 3-D geometric morphometric analysis found that this specimen fell outside range variation in its cranial shape, which was intermediate between modern humans. One problem analyses so far were conducted original specimen, shows slight post-mortem...
Abstract Hailstone structures have been studied for over a century, but so far mainly by manual optical means. This paper presents new texture and microstructure data (i.e. crystal lattice orientations, grain sizes shapes) measured with an Automatic Ice Texture Analyzer, which gives access to high spatial angular resolutions. The hailstones show two main characteristics: (1) they are structured several concentric layers composed of alternating fine equiaxed grains coarse elongated radially...
ABSTRACT A variety of geometric morphometric methods have recently been used to describe dental shape variation in human evolutionary studies. However, the applicability these is limited when teeth are worn or difficult orient accurately. Here we show that elliptical best fits on outlines tissues below crown provide basic size‐ and orientation‐free descriptors. Using dm 2 M 3 as examples, demonstrate descriptors can be for taxonomic purposes, such distinguishing between Neanderthal recent...
Only a few localised ice streams drain most from the Greenland Ice Sheet. Thus, understanding stream behaviour and their temporal variability is crucially important to predict future sea-level change. The interior trunk of 700 km-long North-East Stream (NEGIS) remarkable for lack any clear bedrock channel explain its presence. Here we use isochronous radar reflections an airborne survey as passive tracers deformation. We present first-ever 3-dimensional analysis folding advection...
