Lithic analysis in African archaeology: Advances and key themes
Archaeometry, EarlyView.Abstract Stone artifacts (lithics) preserve for extended periods; thus they are key evidence for probing the evolution of human technological behaviors. Africa boasts the oldest record of stone artifacts, spanning 3.3 Ma, rare instances of ethnographic stone tool‐making, and stone tool archives from diverse ecological settings, making it an anchor for ...

Investigating relationships among strontium, barium, and seasonality in wild baboons
Archaeometry, EarlyView.Abstract Geochemical profiles of Australopithecus africanus and baboon teeth show fluctuating trace elements, possibly reflecting seasonal diets. Here we use laser ablation–inductively coupled plasma–mass spectrometric measurements of calcium‐normalized strontium and barium ratios (Sr/Ca and Ba/Ca) and ion microprobe analyses of oxygen isotopes (δ18O ...

Boreas, EarlyView.The characteristics of settlement of Neanderthals in northern Central Europe during the earlier phases of the Middle Palaeolithic (Marine Isotope Stage 8–6) have been a matter of debate for decades, specifically regarding the population dynamics at such latitudes during the coldest phases. In this paper, we review the known archaeological record of the

Journal of Fish Biology, EarlyView.Abstract Early life‐history traits of seahorses are closely linked to juvenile survival, dispersal potential and the onset of substrate attachment; however, detailed stage‐resolved descriptions remain limited for many Hippocampus species. This study examined reproductive behaviour and early ontogenetic development of the Korean seahorse, Hippocampus ...

Révision de l’espèce Homo erectus (Dubois, 1893)
Bulletins et Mémoires de la Société d’Anthropologie de Paris, 2000 The hypodigm for Homo erectus is a problem which remains unresolved. Most disagreements are based on chronological rather than morphological data. A methodology based neither on simple global similarity nor on chronological position is required to ...

Journal of Anatomy, EarlyView.Graviportal proboscideans differ in limb morphology, adopting slender or more robust long bone morphotypes. Finite element analyses (FEA) on extant and extinct taxa reveal functional differences between morphotypes, with robust humeri exhibiting lower peak stress under neutral and off‐axis loading.

The significance of early hominid cranial variability [PDF]
, 1991 The aims of this thesis are: 1. To examine patterns of morphological variation in the crania of extant species {Pan, Gorilla, Pongo, and H. sapiens) to determine if any common pattern of primate sexual dimorphism exists which could be used in the ...

Nano Select, Volume 7, Issue 10, October 2026.Surface‐modified niosomes are introduced as multifunctional nanoparticles for precision tumor treatment that combine hydrophilic and lipophilic drug encapsulation with ligand‐based targeting via antibodies, peptides, transferrin, and folic acid. This modification leads to increased tumor selectivity, facilitates cell entry, and enables enhanced ...
