However, there is little data available on body size in historical populations; therefore, the relationship between body size and 1918 influenza pandemic outcomes is virtually unknown. Alaskan death records from the Alaska Bureau of Vital Statistics with recorded height and mass at death (<i>n</i> = 2724) were analyzed to illuminate this relationship during both the pandemic (1918–20) and a non-pandemic period (1917, 1921–25). Binomial logistic regression models were fit to predict the likelihood of a P&amp;I death against four other major causes of death, first using only BMI as a predictor, then controlling for demographic variables. BMI alone can predict the probability of P&amp;I death, but only during the pandemic period (<i>p</i> &lt; 0.001). BMI (ORs = 0.90–1.51), all regions (ORs = 2.08–9.17), age (OR = 0.98), sex (male: OR = 0.66–0.75), and ethnicity group (non-Alaska Native: OR = 0.36–0.37) significantly predicted the likelihood of a P&amp;I death during the pandemic. The results suggest that as BMI increases, the risk of P&amp;I death also increases with additional predictors, but only during the 1918 influenza pandemic period. There is no significant relationship between BMI and P&amp;I death outside of pandemic years. This result may contribute an additional unique feature to our understanding of the 1918 influenza pandemic and its epidemiological novelty. This research further contributes new data on historical population biology and contextualizes results within the framework of developmental origins of health and disease for ultimate explanations of differential risks between Alaska Native and settler populations.</p>","PeriodicalId":50809,"journal":{"name":"American Journal of Human Biology","volume":"37 10","pages":""},"PeriodicalIF":1.7,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ajhb.70151","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145196481","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Asymmetrical gene flow was observed within all Roma subpopulations, while the male-biased gene flow was observed only within the predominantly Orthodox group from the central region of Serbia.

This paper reexamines the question of Neandertal cold adaptation using updated fossil, physiological, and archaeological evidence. While some populations lived outside glacial extremes, all faced periodic cold stress, and their survival depended on a diverse set of strategies. Technological buffers, including fire use, hide processing tools, and possible clothing and footwear, likely played a primary role in reducing cold exposure. Anatomically, Neandertals exhibit high body mass, broad trunks, and abbreviated limbs, consistent with thermoregulatory principles. The Neandertal nasal region, long considered paradoxical, now appears well suited to cold-dry air-conditioning; computational fluid dynamics and new endoscopic data support a functionally integrated nasal cavity with substantial internal surface area. Physiological adaptations remain inferential but plausible, including elevated basal metabolism, energy-dense diets, and potential use of brown adipose tissue. These factors likely contributed to high total energy expenditures, enabling thermoregulation in demanding environments. Rather than a single trait or “signature” adaptation, Neandertals present an integrated response to cold stress shaped by geography, development, culture, and genetics. This holistic view reframes Neandertal biology as deeply thermally engaged and sets the stage for targeted tests of function and mechanism in future research.</p>","PeriodicalId":50809,"journal":{"name":"American Journal of Human Biology","volume":"37 10","pages":""},"PeriodicalIF":1.7,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ajhb.70150","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145197338","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
