Latine adults in the US often experience menopause earlier and have more frequent vasomotor symptoms (VMS) compared to non-Latine White adults. These differences may be partly attributed to early-life adversity, such as adverse childhood experiences (ACEs), which may alter energy allocation towards faster maturation and reproductive efforts, potentially shaping variations in menopausal experiences. Using data from a sample of primarily immigrant, Mexican adults living in an agricultural region in California (<i>N</i> = 459), we evaluated the extent to which ACEs were associated with age at menopause and VMS (hot flashes and night sweats). In adjusted models, having ACEs (vs. none) was significantly associated with experiencing hot flashes (1-3 ACEs: odds ratio [OR] = 2.50, 95% confidence interval [CI]: 1.57-4.00; 4+ ACEs: OR = 2.51, 95% CI: 1.49-4.24) and night sweats (1-3 ACEs: OR = 1.67, 95% CI: 1.02-2.76; 4+ ACEs: OR = 2.36, 95% CI: 1.37-4.06) but not earlier menopause (e.g., 1-3 ACEs: HR = 0.85, 95% CI: 0.59-1.21).

In particular, individual and social learning allow populations to accumulate knowledge across generations. Here, we examine how stochasticity in the production and social acquisition of knowledge influences the evolution of learning schedules and cumulative knowledge. Using a mathematical model where learning is stochastic, we show that learning stochasticity enhances cumulative knowledge by generating variability in knowledge levels. This allows selection to enhance population knowledge: individuals who acquire more knowledge by chance are more likely to survive and reproduce, and therefore to transmit their knowledge to the next generation. As knowledge accumulates, social learning exemplars tend to possess more of it, favouring greater time investment in social learning. Because social learning provides access to substantially more knowledge when learning is stochastic, selection also favours the evolution of greater investment into learning, at the expense of a fecundity cost. Moreover, when knowledge enhances fecundity but not survival, learning stochasticity favours learning from parents rather than other adults, because learning stochasticity increases uncertainty about exemplar knowledge, making parenthood a cue for possessing fecundity-enhancing knowledge. Finally, when learning occurs predominantly from parents, learning stochasticity itself is favoured by selection.</p>","PeriodicalId":36414,"journal":{"name":"Evolutionary Human Sciences","volume":"8 ","pages":"e18"},"PeriodicalIF":2.1,"publicationDate":"2026-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13150785/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147869670","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The advent of ancient DNA analysis has made it possible to evaluate past social structures from a genetic perspective as well, with the majority of ancient DNA studies identifying patrilocal communities and highlighting genetic patriline connections.

However, empirical findings on the use of second-order information have been mixed. Drawing upon the literature on group-bounded indirect reciprocity, we tested the hypothesis that individuals would be more sensitive to second-order information when evaluating in-group interactions, compared to when evaluating out-group interactions. We conducted a preregistered online experiment (<i>N</i> = 604), where we independently manipulated group membership (in-group vs. out-group), target behaviour (cooperation vs. defection), and recipient reputation (good vs. bad).

Partly consistently with our hypothesis, when individuals evaluated coopering donors, second-order information influenced reputation for in-group donor-recipient interactions more than for out-group donor-recipient interactions.

Yet individuals can simultaneously belong to multiple groups, which may be nested within larger groupings. Here, we introduce the <i>generalized Bach or Stravinsky game</i>, a co-ordination game with ordered preferences, which allows us to construct a model that captures the overlapping and hierarchical nature of social identity.

Our model also allows agents to express complex social identities through multidimensional signalling, which we use to explore a variety of complex group structures.
