Journal of the Royal Anthropological Institute, EarlyView.This article presents a synthesis of recent developments in the study of human evolution over the past five years. It begins with an overview of hominin species nomenclature and diversity, followed by an examination of the proposed population bottleneck ∼900,000 years ago.

BiologyPhosphorus (P) availability critically limits plant growth in ecosystems. Plants adapt by regulating internal P fractions, yet how these fractions underpin ecological strategies in wild plants remains unclear.

Integrative Zoology, EarlyView.We report the first ontogenetic information for the compression‐preserved Cambrian ecdysozoan worm Cricocosmia jinningensis. Its mosaic growth strategy unifies panarthropod and priapulid developmental patterns. Sclerite allometry reverses at the juvenile‐to‐adult transition, providing the earliest evidence of developmental resource allocation ...

Microbiome Dynamics During Translocation of the Critically Endangered Frog Craugastor ranoides
Animal Conservation, EarlyView.A female Craugastor ranoides fitted with an LB‐2X radio transmitter using a silicone waist‐belt harness for post‐translocation monitoring. ABSTRACT Amphibian populations are declining, and species are going extinct due to habitat loss, climate change, and emerging infectious disease, prompting the increasing use of translocations as a conservation tool.

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 ...

Archaeometry, EarlyView.ABSTRACT Lake sediments are natural archives of past environmental dynamics and how these systems have responded to past climate variability. Sediment geochemistry, governed by local geology and climate processes, is unique to each lake‐catchment and geochemical proxies must be validated for each study site.

A Newly Discovered Tablet‐Making Facility in Nineveh: Insights From Scientific Analysis
Archaeometry, EarlyView.ABSTRACT This paper addresses the question of tablet technology in the Neo‐Assyrian capital city of Nineveh. Recent excavations in the lower town of Nineveh by the Iraqi–Italian Archaeological Expedition uncovered an exceptional assemblage of more than 200 tablets from an elite residence that appears to have included a scriptorium.

Archaeometry, EarlyView.ABSTRACT Vlaardingen (VL) communities on the Dutch West coast (3400–2200 bce) are part of a unique, long‐term continuity in the European Neolithic. Despite large‐scale changes in European populations during the Neolithic, the genomic diversity and cultural practices of VL communities can be retraced to the Mesolithic.

Archaeometry, EarlyView.ABSTRACT Riverine and valley systems across the globe have been central to the development of past urban centres. By AD 900, the Shashe and Limpopo Rivers seem to have facilitated the interaction and integration of early farming communities in southern Africa. This paper focuses on the application of geoarchaeological perspectives made available by the
