All precautions were taken to ensure that primatology students and researchers could safely gather inperson at Boston University for the Seventh Annual NEEP Meeting. This year, Drs. Eva Garrett, Cheryl Knott, and Christopher Schmitt took on the challenge of hosting the conference and creating a sense of normalcy as the meeting returned to its traditional in-person format (Figure 1). As the keynote speaker, Dr. Martin Surbeck (Harvard University) started the conference by presenting his work with wild bonobos along with giving sage advice to the student researchers in the audience. As an adventurous field researcher, Surbeck began with the guidance, “do not assume, check!” When Surbeck began his research, bonobos were known for finding “peace through pleasure” in addition to being female dominant, peaceful, egalitarian, tolerant, and vegetarian. At the Lui Kotale study site, Surbeck and collaborators found a finger from an immature black mangabey in bonobo feces along with a nearby pelt of mangabey hair. This finding challenged the notion that meat eating in bonobos is rare and highlighted the need for more field studies of wild bonobos in order to delineate meaningful differences between bonobos, chimpanzees, and humans. Surbeck later discovered high male reproductive skew among bonobos, leading to questions regarding the attractiveness of males and the potential to monopolize mating opportunities with ovulating females. “Is there a 'Ryan Gosling' bonobo attracting all the ovulating female bonobos?” Surbeck asked the audience. By “zooming out” to see the bigger picture, Surbeck found there are large potential indirect fitness gains for mothers that promote their sons. Rather than females choosing their mates based on “attractive” male characteristics, high-ranking mothers (e.g., Queen Elizabeth as Surbeck suggested) seem to ensure their sons mate more often with ovulating females compared to other males. Collectively, these findings show that bonobos are not necessarily the egalitarian vegetarian ape species they are often assumed to be. Their seemingly tolerant and cooperative behaviors are far more complex than what initially meets the eye. Taking his own advice “to get out there,” Surbeck helped establish a bonobo field site at Kokolopori. From constructing a boat to finding a replacement tire in the middle of nowhere, his group faced arduous challenges at every stage of this journey. In collaboration with the Bonobo Conservation Initiative (BCI), Surbeck has overseen the Kokolopori Bonobo Research Project (KBRP) since 2016. Currently, Surbeck collaborates with his graduate students, post-docs, and colleagues to critically assess our conventional understanding of bonobo sexuality, tolerance, and cooperation as they s","PeriodicalId":47849,"journal":{"name":"Evolutionary Anthropology","volume":"31 1","pages":"5-8"},"PeriodicalIF":3.7,"publicationDate":"2021-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/evan.21932","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39760826","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A growing body of literature demonstrates that adults retain brown adipose tissue (BAT) which may play a role in non-shivering thermogenesis. In this narrative review, we apply the timescales of adaptation framework in order to explore the adaptive significance of human BAT. Human variation in BAT is shaped by multiple adaptive modes (i.e., allostasis, acclimatization, developmental adaptation, epigenetic inheritance, and genetic adaptation), and together the adaptive modes act as an integrated system. We hypothesize that plasticity in BAT facilitated the successful expansion of human populations into circumpolar regions, allowing for selection of genetic adaptations to cold climates to take place. Future research rooted in human energetics and biocultural perspectives is essential for understanding BAT's adaptive and health significance.</p>","PeriodicalId":47849,"journal":{"name":"Evolutionary Anthropology","volume":"31 2","pages":"75-91"},"PeriodicalIF":3.7,"publicationDate":"2021-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39728852","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tinbergen clarified that these ‘levels of analysis’ are complementary, not competing, thereby avoiding many fruitless scientific debates. However, the relationships among the four levels was never established. Here, we propose ‘leveling’ Tinbergen's questions to a single temporal timescale divided into <i>causes</i> (encompassing mechanism, development, and evolution) and <i>consequences</i> (encompassing function). Scientific advances now seamlessly link evolution, development, and mechanism into a continuum of ‘causes’.
