However, in nature, true panmictic populations are vanishingly rare. As an idea conceived for modelling evolutionary dynamics, it has been thought that the assumption of panmixia was formalised during the development of the Modern Synthesis. Here, we show that while the idea's longevity is almost certainly due to its mathematical convenience, it became embedded in evolutionary thought much earlier, initially as a way to reconcile long-standing essentialist ideas with the advent of Darwin's theories. Though the principles of essentialism and reversion have been largely rejected, these ideas persist in shaping assumptions made about populations in contemporary genetics research, including how they are conceptualised and sampled. This legacy has important implications for the interpretation of genomic findings in human evolution, conservation and medicine. From an evaluation of this history and its legacy, we contend that while the panmictic population concept has been, and continues to be useful, with the generation of terabytes of genomic data in the 21st century, its utility is likely to diminish as the need for continuous space models grows.</p>\u0000 </section>\u0000 </div>","PeriodicalId":8085,"journal":{"name":"Annals of Human Genetics","volume":"89 5","pages":"274-284"},"PeriodicalIF":1.2,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ahg.70015","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144726877","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is characterized by the presence of comedones (blackheads), papules, and pustules. The condition is associated with sebaceous glands in the face and chest, which produce an oily substance called sebum. In developed nations, acne affects over 80% of adolescents. Mild disease usually resolves spontaneously. More severe acne can leave permanent, disfiguring scarring and strongly affects quality of life. In those cases, medical intervention is warranted. To date, antibiotics and retinoids (synthetic vitamin A derivatives) are the mainstays of treatment. Depending on the severity of the condition, these drugs may be administered either topically or systemically.</p><p>Whilst generally effective, they do come with significant drawbacks. Antibiotic use for treating acne is contributing to antimicrobial resistance. In addition, indiscriminate eradication of the skin microbiome negatively impacts skin health. Retinoids are teratogenic and have other undesirable side effects, such as skin irritation and increased UV sensitivity. Thus, there is a clear need for effective interventions that target the underlying disease mechanism, minimizing side effects.</p><p>Rapid progress has recently been made in understanding the mechanisms underlying acne. For decades, it was assumed that blackhead formation results from the accumulation of sebum in the hair follicle opening, due to increased sebum production at the onset of puberty. Subsequent colonization by the commensal bacterium <i>Cutibacterium acnes</i> then was thought to cause inflammation. It was also postulated that this micro-organism could induce blackheads. There are, however, several problems with this supposed sequence of events, not the least of which is that it doesn't explain how retinoids work, or why sebaceous glands associated with blackheads are atrophic and hence produce less sebum, not more.</p><p>Both GWAS and single gene disorders unequivocally indicate stem/progenitor cell maintenance and cellular migration as the most important processes in the pathogenesis of acne.
