Speleothem climate capture of the Neanderthal demise
… climatic zones and was the last refuge of the Neanderthals. The influence of climate changes on Neanderthal populations remains a mystery due to the lack of independently-dated high-resolution terrestrial records of past climate and environmental change from the Iberian Peninsula. The primary …

The Distribution of Neanderthal Ancestry Across Populations And Within Genomes
… in time and space with archaic humans such as Neanderthals and Denisovans. We now know that modern and archaic humans interbred, and that modern human populations carry some amount of archaic ancestry. The complexities of this admixture history, however, have persisted as outstanding questions …

Patterns of Archaic Hominin DNA in Modern Human Genomes
… humans that is similar to the divergence time of Neanderthals. In a sample of 379 European and 279 East Asian genomes, I identify on average 1/4 of each individual's introgressed Neanderthal sequence, composing a total of 600Mb of the Neanderthal genome. I use characteristics of this sequence to …

Analyse de la répartition spatiale des restes fauniques du site éémien de Caours (Somme). Apport des systèmes d'information géographique.
… us a large amount of data about this period of Neanderthal history. We now questioning about the choice of this locality and the spatial organisation of Neanderthal. Then, spatial analysis using the Geographic Information System (GIS) appear to being a useful tool to answer it. We show the …

Image analysis in the morphological and morphometric study of teeth
… is furnished by the study of certain early Neanderthal and preneanderthal molars recovered in two caves in southern Italy [Grotta Taddeo (Taddeo Cave) and Grotta del Poggio (Poggio Cave), near Marina di Camerata, Campania]. To these we can add other molars of Neanderthal and modern man of …

A comprehensive analysis of long bone curvature in Neanderthals and modern humans using 3D morphometrics
Since their discovery Neanderthals were described as having a marked degree of anteroposterior curvature of the femoral shaft. Although initially believed to be pathological, subsequent discoveries of Neanderthal remains made femoral curvature as well as the lateral curvature of the radius to be …

Investigating the genetic diversity, population structure and archaic admixture history in worldwide human populations using high-coverage genomes
… Applying the model on the HGDP dataset using two Neanderthal genomes and one Denisova genome, I detected variations in the level of archaic ancestry across continental regions, populations, and individuals within each population. I further compared Neanderthal and Denisovan segments regarding …

Neanderthal and Modern Human Adaptations to Climate Change in Southwest Asia: Climate Reconstruction of Marine Isotope Stage 5 to 3 based on small mammal records from Shanidar Cave (Iraqi Kurdistan)
… sapiens (‘Modern Humans’) and the extinction of Neanderthals in Eurasia between 50,000 to 30,000 years BP (Higham et al. 2014). The exact causes of Neanderthal extinction are still widely debated, but one widely considered theory is that Neanderthals were less able to cope with rapid climate …

Faunal and human biogeography during the Terminal Pleistocene.
… taxon was investigated in detail: the Neanderthal. The climatic niche of the Neanderthal was explored with climatic niche modelling. The models confirm the Neanderthal was a temperate adapted taxon that retreated to the southwest of Europe during MIS3. Furthermore, the climatic niche …

Archaeology, archaeogenetics, and identity genetic research within the Maltese context
… genetic make-up) and macro-scale (human and Neanderthal genome). Given the current political climate in Europe and Malta, which has seen a steady rise in nationalistic and xenophobic sentiments, as well as the sensitive nature of the subject matter, archaeogenetic discoveries can provoke a …

Using 3-D Geometric Morphometric Techniques to Further Understand the Relationship Between Neanderthals and Homo sapiens
… has been a heated subject of debate since Neanderthals were first recognized. Neanderthals are either a distinctly separate species from Homo sapiens that were replaced by Homo sapiens without any genetic interaction, which supports the taxonomical title for Neanderthals as Homo …

Of mice and hominins: using the craniomandibular morphology of hybrid mice to better understand hybrid morphologies in the Hominin fossil record
Since the sequencing of the Neanderthal genome in 2010, there has been an explosion of molecular research into hybridization and gene flow among hominin taxa in the Late Pleistocene. However, little research has focussed on how hybridization affects skeletal morphology. In regions and time periods …

Insights into the genomic histories of diverse human populations using whole-genome sequencing analysis.
… I show that Arabian populations have the lowest Neanderthal ancestry of all non-African populations tested, which is explained by them having elevated Basal Eurasian ancestry. By comparing Levantines and Arabian historical population sizes, I find a divergence that starts before the Neolithic …

Le faune del Paleolitico medio-superiore in Nord Italia: nuovi dati archeozoologici dal Riparo Mochi e dal Riparo Tagliente

It is widely debated how and in what time frame this replacement occurred, and if, when, and where the two human species interacted with eachother. In order to understand the …

Strontium isotope tracing of prehistoric human mobility in France

Cave pollen taphonomy in Kurdish Iraq

HUMAN GENOME VARIATIONS AND EVOLUTION WITH A FOCUS ON THE ANALYSIS OF TRANSPOSABLE ELEMENTS
… recent evolutionary analyses involving the Neanderthal genome. The three data chapters presented in this thesis conclude that the tandem repeats and transposable elements are not two entirely distinctly isolated elements as over 20% TRs are actually derived from TEs. Certain subfamilies of …
