Estimating the phylogeny and divergence times of primates using a supermatrix approach
Background
The primates are among the most broadly studied mammalian orders, with the published literature containing extensive analyses of their behavior, physiology, genetics and ecology. The importance of this group in medical and biological research is well appreciated, and explains the numerous molecular phylogenies that have been proposed for most primate families and genera. Composite estimates for the entire order have been infrequently attempted, with the last phylogenetic reconstruction spanning the full range of primate evolutionary relationships having been conducted over a decade ago.
Results
To estimate the structure and tempo of primate evolutionary history, we employed Bayesian phylogenetic methods to analyze data supermatrices comprising 7 mitochondrial genes (6,138 nucleotides) from 219 species across 67 genera and 3 nuclear genes (2,157 nucleotides) from 26 genera. Many taxa were only partially represented, with an average of 3.95 and 5.43 mitochondrial genes per species and per genus, respectively, and 2.23 nuclear genes per genus. Our analyses of mitochondrial DNA place Tarsiiformes as the sister group of Strepsirrhini. Within Haplorrhini, we find support for the primary divergence of Pitheciidae in Platyrrhini, and our results suggest a sister grouping of African and non-African colobines within Colobinae and of Cercopithecini and Papionini within Cercopthecinae. Date estimates for nodes within each family and genus are presented, with estimates for key splits including: Strepsirrhini-Haplorrhini 64 million years ago (MYA), Lemuriformes-Lorisiformes 52 MYA, Platyrrhini-Catarrhini 43 MYA and Cercopithecoidea-Hominoidea 29 MYA.
Conclusion
We present an up-to-date, comprehensive estimate of the structure and tempo of primate evolutionary history. Although considerable gaps remain in our knowledge of the primate phylogeny, increased data sampling, particularly from nuclear loci, will be able to provide further resolution.

Tailoring cultural offers to meet the needs of older people during uncertain times: a rapid realist review
Background
Non-medical issues (e.g. loneliness, financial concerns, housing problems) can shape how people feel physically and psychologically. This has been emphasised during the Covid-19 pandemic, especially for older people. Social prescribing is proposed as a means of addressing non-medical issues, which can include drawing on support offered by the cultural sector.
Method
A rapid realist review was conducted to explore how the cultural sector (in particular public/curated gardens, libraries and museums), as part of social prescribing, can support the holistic well-being of older people under conditions imposed by the pandemic. An initial programme theory was developed from our existing knowledge and discussions with cultural sector staff. It informed searches on databases and within the grey literature for relevant documents, which were screened against the review’s inclusion criteria. Data were extracted from these documents to develop context-mechanism-outcome configurations (CMOCs). We used the CMOCs to refine our initial programme theory.
Results
Data were extracted from 42 documents. CMOCs developed from these documents highlighted the importance of tailoring—shaping support available through the cultural sector to the needs and expectations of older people—through messaging, matching, monitoring and partnerships. Tailoring can help to secure benefits that older people may derive from engaging with a cultural offer—being distracted (absorbed in an activity) or psychologically held, making connections or transforming through self-growth. We explored the idea of tailoring in more detail by considering it in relation to Social Exchange Theory.
Conclusions
Tailoring cultural offers to the variety of conditions and circumstances encountered in later life, and to changes in social circumstances (e.g. a global pandemic), is central to social prescribing for older people involving the cultural sector. Adaptations should be directed towards achieving key benefits for older people who have reported feeling lonely, anxious and unwell during the pandemic and recovery from it.

Morphometric characterization of Holocene mandibles expands the ecological baseline for understanding gibbon extinction dynamics
Human activities have driven biodiversity loss for millennia, and conservation of ‘refugee species’ that survive as remnant populations requires insights from historical baselines. However, reconstructing the past distribution and ecology of such species is challenging due to data limitations with specimen-based archives. Here, we assess the taxonomic identity of two gibbon mandibles from the Wumingshan Neolithic site in Guangxi, China. Although ancient DNA extraction was unsuccessful, a suite of linear and geometric morphometric analyses using dental and mandibular characters reveals that these mandibles fall within or close to variation shown by extant Chinese Nomascus gibbons and can be assigned to the cao vit gibbon N. nasutus . This is now one of the world’s rarest mammals, with a surviving population of 74 individuals in one site. Comparative assessment of bioclimatic, abiotic and anthropogenic parameters for Wumingshan and other sites where N. nasutus historically occurred reveals the species was formerly a landscape generalist but is now restricted to a high-elevation refugium with reduced human pressures. Our multidisciplinary analyses provide a new baseline on niche requirements and vulnerability for N. nasutus with implications for population management, demonstrating the importance of integrating environmental archives into conservation planning.

Effects of a museum-based social prescription intervention on quantitative measures of psychological wellbeing in older adults
Aims:
To assess psychological wellbeing in a novel social prescription intervention for older adults called Museums on Prescription and to explore the extent of change over time in six self-rated emotions (‘absorbed’, ‘active’, ‘cheerful’, ‘encouraged’, ‘enlightened’ and ‘inspired’).
Methods:
Participants (n = 115) aged 65–94 years were referred to museum-based programmes comprising 10 weekly sessions, by healthcare and third sector organisations using inclusion criteria (e.g. socially isolated, able to give informed consent, not in employment, not regularly attending social or cultural activities) and exclusion criteria (e.g. unable to travel to the museum, unable to function in a group situation, unlikely to be able to attend all sessions, unable to take part in interviews and complete questionnaires). In a within-participants’ design, the Museum Wellbeing Measure for Older Adults (MWM-OA) was administered pre-post session at start-, mid- and end-programme. A total of 12 programmes, facilitated by museum staff and volunteers, were conducted in seven museums in central London and across Kent. In addition to the quantitative measures, participants, carers where present, museum staff and researchers kept weekly diaries following guideline questions and took part in end-programme in-depth interviews.
Results:
Multivariate analyses of variance showed significant participant improvements in all six MWM-OA emotions, pre-post session at start-, mid- and end-programme. Two emotions, ‘absorbed’ and ‘enlightened’, increased pre-post session disproportionately to the others; ‘cheerful’ attained the highest pre-post session scores whereas ‘active’ was consistently lowest.
Conclusion:
Museums can be instrumental in offering museum-based programmes for older adults to improve psychological wellbeing over time. Participants in the study experienced a sense of privilege, valued the opportunity to liaise with curators, visit parts of the museum closed to the public and handle objects normally behind glass. Participants appreciated opportunities afforded by creative and co-productive activities to acquire learning and skills, and get to know new people in a different context.

The transition from in-person to virtual museum programing for individuals living with chronic pain – A formative evaluation
Museum engagement may be an effective approach for decreasing social disconnection and pain among individuals living with chronic pain. In October 2019, we launched a randomized controlled trial to assess the feasibility of museum engagement for individuals living with chronic pain; the study was halted in March, 2020 due to Covid-19-related safety concerns. This paper describes the process of transitioning from in-person to virtual museum programing in order to continue the study. Virtual museum programing is a feasible option for individuals living with chronic pain that is amenable to research and which may improve accessibility, inclusivity, and scalability relative to in-person programing.

Museums and art galleries as partners for public health interventions
The majority of public health programmes are based in schools, places of employment and in community settings. Likewise, nearly all health-care interventions occur in clinics and hospitals. An underdeveloped area for public health-related planning that carries international implications is the cultural heritage sector, and specifically museums and art galleries. This paper presents a rationale for the use of museums and art galleries as sites for public health interventions and health promotion programmes through discussing the social role of these organisations in the health and well-being of the communities they serve. Recent research from several countries is reviewed and integrated into a proposed framework for future collaboration between cultural heritage, health-care and university sectors to further advance research, policy development and evidence-based practice.

Rapid Evidence Review of Community Engagement and Resources in the UK during the COVID-19 Pandemic: How Can Community Assets Redress Health Inequities?
Community engagement, such as participating in arts, nature or leisurely activities, is positively associated with psychological and physiological wellbeing. Community-based engagement during the COVID-19 pandemic facilitated informal and local mutual aid between individuals. This rapid evidence review assesses the emergence of community-based arts, nature, music, theatre and other types of cultural engagement amongst UK communities in response to the COVID-19 pandemic. Here, we focus on all community engagement with a sub-focus on provisions accessed by and targeted towards vulnerable groups. Two hundred and fifty-six resources were included that had been created between February 2020 and January 2021. Resources were identified through Google Scholar, PubMed, Web of Science, MedRXic, PsycharXiv and searches for grey literature and items in the public domain. The majority reported services that had been adapted to become online, telephone-based or delivered at a distance from doorsteps. Several quality assessment frameworks were used to evaluate the quality of data. Whilst a number of peer-reviewed, grey literature and public domain articles were identified, less than half of the identified literature met quality thresholds. The pace of the response to the pandemic may have meant that robust evaluation procedures were not always in place.

The Impact of Culture-, Health- and Nature-Based Engagement on Mitigating the Adverse Effects of Public Health Restrictions on Wellbeing, Social Connectedness and Loneliness during COVID-19: Quantitative Evidence from a Smaller- and Larger-Scale UK Survey
Numerous UK surveys conducted during COVID-19 examined the pandemic’s detrimental effects on health, and the consequences of lockdown and other public health restrictions on mental health. Some surveys considered specific populations and social inequities exacerbated during COVID-19. Fewer surveys examined the ways in which the adverse effects of public health restrictions, such as lockdown, shielding and social distancing, might be alleviated. Drawing upon self-determination theory, the purpose of the current study was to assess whether culture-, health- and nature-based engagement would mitigate the effects of these restrictions on psychological wellbeing, social connectedness and loneliness. Quantitative data from a smaller-scale survey (n = 312) and a subset of questions embedded in a larger-scale survey (n = 3647) were analyzed using univariate and multivariate methods. Frequency of engagement, whether participation was online or offline and with or without other people, and the extent to which type of participation was associated with psychological wellbeing, social connectedness and loneliness were examined. Sports and fitness, gardening and reading occurred frequently in both surveys. For the smaller-scale survey, increases in connectedness and frequency of participation and decreases in loneliness were significantly associated with improved wellbeing, whereas the type of participation and age range were not significant predictors. Outcomes from the smaller-scale survey approximated the larger-scale survey for measures of loneliness, type and frequency of participation and proportion of respondents in each age range. As the frequency of participation was a significant predictor of wellbeing, but the type of participation was not significant, the findings implied that any type of participation in a sufficient quantity would be likely to boost wellbeing.

New genus of extinct Holocene gibbon associated with humans in Imperial China
Human activities are causing extinctions across a wide array of taxa. Yet there has been no evidence of humans directly causing extinction among our relatives, the apes. Turvey et al. describe a species of gibbon found in a 2200- to 2300-year-old tomb ascribed to a Chinese noblewoman. This previously unknown species was likely widespread, may have persisted until the 18th century, and may be the first ape species to have perished as a direct result of human activities. This discovery may also indicate the existence of unrecognized primate diversity across Asia. Science , this issue p. 1346 A previously unknown gibbon species found in a Chinese tomb suggests that past Asian ape diversity has been lost. Although all extant apes are threatened with extinction, there is no evidence for human-caused extinctions of apes or other primates in postglacial continental ecosystems, despite intensive anthropogenic pressures associated with biodiversity loss for millennia in many regions. Here, we report a new, globally extinct genus and species of gibbon, Junzi imperialis , described from a partial cranium and mandible from a ~2200- to 2300-year-old tomb from Shaanxi, China. Junzi can be differentiated from extant hylobatid genera and the extinct Quaternary gibbon Bunopithecus by using univariate and multivariate analyses of craniodental morphometric data. Primates are poorly represented in the Chinese Quaternary fossil record, but historical accounts suggest that China may have contained an endemic ape radiation that has only recently disappeared.
