Although masturbation by captive nonhuman primates is sometimes considered abnormal or, at least, undesirable behaviour (e.g., Mallapur & Choudhury 2003), masturbation also occurs under natural conditions and may represent a phylogenetically ancient and widespread trait in primates (Thomsen & Sommer 2017). Several studies have reported masturbation in wild male primates living in multimale–multifemale groups where sperm competition occurs (e.g., Temminck’s red colobus, Piliocolobus badius temminckii; Starin 2004; Japanese macaque, Macaca fuscata; Thomsen & Soltis 2004; rhesus macaque, Macaca mulatta; Dubuc et al. 2013). While the hypothesis that male masturbation functions to increase sperm quality (Baker & Bellis 1993) received support in one study of Japanese macaques (Thomsen & Soltis 2004), masturbation leading to ejaculation was observed rather rarely in most reports, suggesting alternative explanations require consideration (Starin 2004; Dubuc et al. 2013). In chimpanzees, masturbation occurs commonly in captive settings where it has been linked to restricted rearing, which can impede development of speciestypical social and sexual behaviour (Kollar et al. 1968; Rogers & Davenport 1969; Lopresti-Goodman et al. 2013). Masturbation by captive chimpanzees is performed by hand, foot or mouth, against a cage wall or screen, or sometimes using a manipulable object (Shefferly & Fritz 1992). In the wild, object-assisted masturbation occurs in male long-tailed macaques (Macaca fascicularis), which stimulate their genitals using stones (Cenni et al. 2020). Such self-directed employment of a manipulable object meets the criteria of an animal ‘tool’ (Shumaker et al. 2011). In contrast to captivity, masturbation appears to be rare among male chimpanzees in the wild. Male chimpanzees of all ages at Gombe and Mahale, Tanzania, manipulated (or ‘fumbled’ or ‘fiddled’ with) their erect penises occasionally, but this was never observed to lead to ejaculation (van Lawick-Goodall 1968; Nishida 1997). Recently, Nakamura (2018) described an infant chimpanzee at Mahale ‘copulating’ with a discarded fruit wadge, which was likened to a ‘sex toy’. Besides this, there seem to be no other reports of wild male chimpanzees using manipulable objects as tools in sexual behaviour. We observed a wild subadult male chimpanzee at Bulindi, Uganda, using a novel human object—a discarded plastic bottle—as a masturbatory tool. While anecdotal (Ramsay & Teichroeb 2019), this unusual observation raises questions about the function of masturbation in male chimpanzees, and contributes to an understanding of the range in behavioural responses of wild apes to novel objects.","PeriodicalId":358068,"journal":{"name":"Pan Africa News","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127240582","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This was not because I was uninterested, but because it takes me a signif icant amount of t ime to read through a 352-page academic book in English. The reading process actually took three weeks, not simply because of my modest English ability, but also because the book contained rather intricate philosophical discussions referring to Rousseau, Heidegger, Merleau‒Ponty, etc. Nonetheless, I felt compelled to finish because the book’s theme is quite relevant to my own research and many of the people mentioned in the text are familiar to me. In brief, this book is an ethnography of “cultural primatologists” studying chimpanzees. Two famous primatologists, one from Europe and another from Japan, are the main figures of the book, although many other supporting individuals appear at relevant points. These two eminent scholars differ in various ways, which readers will learn in detail from the book, but I would like to highlight their commonalities. First, both study western subspecies of chimpanzees, field studies of which started later than those of eastern subspecies. Second, both belong to academic institutions where they were able to delve entirely into research, avoiding the need to devote time to undergraduate teaching. Third, the two were heads of their respective institutions while also conducting their own research projects (so, they have long been “alpha males!”). Fourth, their research teams are highly international in terms of membership. I draw attention to these points as I think they can affect the behaviors of researchers in the same way as the leaders’ regional or cultural origins. The descriptions of these two stalwarts by Langlitz were quite interesting and useful. Being Japanese myself, I was more familiar with the situation in Japan, but discovered a great deal from accounts of the Max Planck team. For example, it was interesting to learn of the very refined hygiene measures taken at the field site, the important role of a specialized statistician at the institute, the overhabituation problem of chimpanzees, and the tendency for students to rely exclusively on electronic devices to take data and even to read e-books in the forest (though this last point may be more of a generational difference than a cultural one), etc. Perhaps Western readers can learn likewise from descriptions of the Japanese side. The aim of this book is not just to describe the behaviors of two human alpha males, of course. By going into the field sites and laboratories of these primatologists, Langlitz’s ultimate aim is to understand the reflections of “cultural primatologists” from the viewpoint of cultural anthropology. While Langlitz is well aware that his observations are “very much skewed toward the researchers who allowed me” (p. 12), he looks more broadly at the controversy over whether or not chimpanzees have cultures by comparing the backgrounds of “field stu","PeriodicalId":358068,"journal":{"name":"Pan Africa News","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125304862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
