And Baby Makes Three
In group‐living primates, male investment in infants is highly variable. Previous research on polygynandrous primates found that male care of infants, whether direct or indirect, may be a means to increase offspring survival, increase social status, invest in future mating opportunities, and/or invest in future social or coalition partners, any of which may increase fitness outcomes. Relationships between male white‐faced capuchins ( Cebus imitat…
Reduction of bitter taste receptor gene family in folivorous colobine primates relative to omnivorous cercopithecine primates
Bitter taste perception is important in preventing animals from ingesting potentially toxic compounds. Whole-genome assembly (WGA) data have revealed that bitter taste receptor genes ( TAS2R s) comprise a multigene family with dozens of intact and disrupted genes in primates. However, publicly available WGA data are often incomplete, especially for multigene families. In this study, we employed a targeted capture (TC) approach specifically probin…

Genetic variation of olfactory receptor gene family in a Japanese population
The olfactory receptor (OR) gene family is comprised of hundreds of intact and disrupted genes in humans. The compositions and copy number variation (CNV) of disrupted and intact OR genes among individuals is expected to cause variation in olfactory perception. However, little is known about OR genetic variation in many human populations. In this study, we used targeted capture enrichment and massive parallel short-read sequencing methods to exam…
Survey report on the current activity of research and education of anthropology by the members of the Anthropological Society of Nippon in 2021
日本の学会や学術研究を取り巻く状況は年々厳しくなっている。そうした状況に適切に対処していくための基礎データを得る目的で,2021年8–9月に,日本人類学会の会員に対してウェブ調査を実施した。(1)会員の職位による研究活動や教育活動の状況,(2)科研費小区分「自然人類学」に対する意識と申請状況,(3)会員の科研費審査への関与状況,(4)自然人類学の下支えのための方策についてのアンケートに対し,会員の23%にあたる123件の有効回答があった。分析の結果,任期の定めのない常勤職では研究・教育活動に割ける時間的余裕が圧倒的に不足している,有期雇用者(ポスドク,テニュアトラック,非常勤講師など)は研究活動に際して専門的な設備やフィールドにアクセスしづらく所属組織からの理解も得づらい,学生では研究に対する意欲を維持しづらい,という回答傾向があった。科研費小区分に「自然人類学」があるほうがよいと答えた回答者の割合は75%だったが,過去5年間以内に研究代表者として「自然人類学」に科研費を申請したことがあ…

The allele frequency of ALDH2*Glu504Lys and ADH1B*Arg47His for the Ryukyu islanders and their history of expansion among East Asians
OBJECTIVES: A cline of frequencies of the derived allele of the ALDH2 gene, which causes a deficiency of an enzyme and "facial flushing" in humans who drink alcohol, has been known among the people of the Japanese archipelago. This cline is conventionally explained by admixture with immigrants from the Asian continent occurring during the Yayoi period. Previous studies lack sufficient data from the peripheral regions of the indigenous Jomon peopl…
Infant mortality in white‐faced capuchins
Infanticide is common in the context of alpha male replacements (AMR), particularly in groups where alpha males experience high reproductive skew and the infants are unlikely to be related to a new alpha male. We examined the relationship between the rate of infant mortality, infant age, and the occurrence and type of AMR in white-faced capuchin monkeys (Cebus capucinus imitator) of the Santa Rosa population in Sector Santa Rosa, Área de Conserva…
Paternal kin recognition and infant care in white‐faced capuchins ( Cebus capucinus )
Evidence for paternal kin recognition and paternally biased behaviors is mixed among primates. We investigate whether infant handling behaviors exhibit paternal kin biases in wild white-faced capuchins monkeys (Cebus capucinus) by comparing interactions between infants and genetic sires, potential sires, siblings (full sibling, maternal, and paternal half-siblings) and unrelated handlers. We used a linear mixed model approach to analyze data coll…
The Behavioral Ecology of Color Vision
Color Vision Variation as Evidenced by Hybrid L/M Opsin Genes in Wild Populations of Trichromatic Alouatta New World Monkeys
Platyrrhine (New World) monkeys possess highly polymorphic color vision owing to allelic variation of the single-locus L/M opsin gene on the X chromosome. Most species consist of female trichromats and female and male dichromats. Howlers (genus Alouatta ) are an exception; they are considered to be routinely trichromatic with L and M opsin genes juxtaposed on the X chromosome, as seen in catarrhine primates (Old World monkeys, apes, and humans). …
Male philopatry in spider monkeys revisited
Dispersal patterns are critical for understanding social systems as they influence social interactions and relationships. Spider monkeys ( Ateles spp.) are typically described as being characterized by male philopatry and female dispersal, with these patterns reflected in stronger affiliative and cooperative relationships among males than among females. Recent findings, however, indicate that male–male relationships may not be as uniformly strong…
Why Aye‐Ayes See Blue
The capacity for cone‐mediated color vision varies among nocturnal primates. Some species are colorblind, having lost the functionality of their short‐wavelength‐sensitive‐1 ( SWS1 ) opsin pigment gene. In other species, such as the aye‐aye ( D aubentonia madagascariensis ), the SWS1 gene remains intact. Recent studies focused on aye‐ayes indicate that this gene has been maintained by natural selection and that the pigment has a peak sensitivity …
Autosomal and Y-chromosomal STR markers reveal a close relationship between Hokkaido Ainu and Ryukyu islanders
Understanding the phylogenetic relationship between Hokkaido Ainu and Ryukyu islanders has been of great interest in human genetics, archaeology, and anthropology. We examined short tandem repeat (STR) polymorphisms on autosomes and Y-chromosomes for Ainu, and compared this with data from Ryukyu islanders. A statistical test for nine autosomal (A-STR) loci gave no indication that the Ainu had experienced any bottleneck effect(s). The genetic dist…
A population genetic study on the relationship between medaka fish and the spread of wet-rice cultivation across the Japanese archipelago
It has been generally thought that a tiny freshwater fish, medaka (Oryzias latipes), has expanded its habitat into the Japanese archipelago as wet-rice cultivation spread across the region, and hence the distribution of medaka should be a matter of anthropological interest. However, there has been no study to verify this popular belief. To address the issue, we sampled wild medaka, and undertook genetic analyses of its populations. We collected 9…
A genetic analysis of the Sakishima islanders reveals no relationship with Taiwan aborigines but shared ancestry with Ainu and main‐island Japanese
The Sakishima islands are members of the Ryukyu island chain, stretching from the southwestern tip of the Japanese archipelago to Taiwan in the East China Sea. Archaeological data indicate cultural similarities between inhabitants of prehistoric Sakishima and Neolithic Taiwan. Recent studies based on tooth crown traits show remarkably high inter‐island diversity among Ryukyu islanders, suggesting that the Sakishima islanders might have genetic ba…

Demonstration of a genotype–phenotype correlation in the polymorphic color vision of a non‐callitrichine New World monkey, capuchin ( Cebus apella )
Color‐vision polymorphism in New World monkeys occurs because of an allelic polymorphism of the single‐copy red‐green middle‐to‐long‐wavelength‐sensitive (M/LWS) opsin gene on the X chromosome. Because color‐vision types can readily be estimated from allelic types of the M/LWS opsin gene, this polymorphic system offers researchers an excellent opportunity to study the association between vision and behavior. As a prerequisite for such studies, ge…

Color‐vision polymorphism in wild capuchins ( Cebus capucinus ) and spider monkeys ( Ateles geoffroyi ) in Costa Rica
New World monkeys are unique in exhibiting a color‐vision polymorphism due to an allelic variation of the red‐green visual pigment gene. This makes these monkeys excellent subjects for studying the adaptive evolution of the visual system from both molecular and ecological viewpoints. However, the allele frequencies of the pigments within a natural population have not been well investigated. As a first step toward understanding the relationship be…
Advantage of dichromats over trichromats in discrimination of color‐camouflaged stimuli in nonhuman primates
Due to a middle‐ to long‐wavelength‐sensitive (M/LWS) cone opsin polymorphism, there is considerable phenotypic variation in the color vision of New World monkeys. Many females have trichromatic vision, whereas some females and all males have dichromatic vision. The selective pressures that maintain this polymorphism are unclear. In the present study we compared the performance of dichromats and trichromats in a discrimination task. We examined t…
