Abstract Objectives Stable isotope analysis of sequential dentine samples is a potentially powerful method to reveal insights into early life‐histories of individuals in the past. Dentine incremental growth structures are complex, however, and current approaches that apply horizontal sectioning of demineralized tooth halves or quarters risk combining multiple growth layers and may include unwanted cementum or secondary dentine. They also require destruction of large parts of a tooth....

Abstract Objectives The paleontological description and comparative analysis using discrete morphology, morphometrics (linear and geometric) and cross‐sectional geometry of three femoral diaphyseal sections from the Middle Pleistocene site of Hualongdong, China. Materials and Methods The material consists of the original Hualongdong femoral fossils and available data on femoral diaphyses from Middle and Late Pleistocene archaic humans and Middle and earlier Upper Paleolithic modern humans....

Abstract The transition from solitary life to sociality is considered one of the major transitions in evolution. In primates, this transition is currently not well understood. Traditional verbal models appear insufficient to unravel the complex interplay of environmental and demographic factors involved in the evolution of primate sociality, and recent phylogenetic reconstructions have produced conflicting results. We therefore analyze a theoretical model for the evolution of female social philopatry...

Convalescent plasma (CP) therapy has been used since the early 1900s to treat emerging infectious diseases; its efficacy was later associated with the evidence that polyclonal neutralizing antibodies can reduce the duration of viremia. Recent large outbreaks of viral diseases for which effective antivirals or vaccines are still lacking has renewed the interest in CP as a life-saving treatment. The ongoing COVID-19 pandemic has led to the scaling up of CP therapy to unprecedented levels. Compared...
