Mobile consumers influence the shoreward edge of intertidal seagrass ecosystems

Journal of Animal Ecology, EarlyView.
Ecological paradigms suggest that the environmentally stressful edge of a habitat is determined by physical factors. The work finds that, counter to these paradigms, an environmentally stressful edge can also be impacted by biotic interactions and are more complex than suggested.

Recent progress in studies of the last million years of human physical and behavioural evolution Avancées récentes dans l’étude du dernier million d'années d’évolution physique et éthologique de l'espèce humaine

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.

The emergence and complexification of symbolic practices in the Homo lineage: an archaeological and cognitive perspective Émergence et complexification des pratiques symboliques dans la lignée Homo : une approche archéologique et cognitive

Journal of the Royal Anthropological Institute, EarlyView.
Recent archaeological discoveries, reviewed in this essay, challenge traditional views on the emergence of human symbolic cognition. Once believed to have originated in Europe around 40,000 years ago, new evidence shows it emerged much earlier across diverse regions.

The First Quantitative Evidence of Ontogenetic Growth in the Early Cambrian Ecdysozoan Worm Cricocosmia jinningensis Reveals the Earliest Energy Reallocation

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 ...
