Species interactions that vary across environments can create geographical mosaics of genetic coevolution. However, traits mediating species interactions are sometimes culturally inherited. Here we show that traditions of interspecies communication between people and wild birds vary in a culturally determined geographical mosaic. Honey hunters in different parts of Africa use different calls to communicate with greater honeyguides (Indicator indicator) that lead them to bees’ nests. We show experimentally that honeyguides in Tanzania and Mozambique discriminate among honey hunters’ calls, responding more readily to local than to foreign calls. This was not explained by variation in sound transmission and instead suggests that honeyguides learn local human signals. We discuss the forces stabilizing and diversifying interspecies communication traditions, and the potential for cultural coevolution between species.

In Search of a Borderland: Material Culture Patterns on the Southern Limits of the North American Southwest
Recent research conducted in southern Sonora, Mexico provides an opportunity to revisit debates about interaction between Mesoamerica and the North American Southwest (NAS). In the borderland between these traditions, communities show few signs of cultural amalgamation, instead exhibiting either an avoidance of overt identity markers or an emphasis on more local connections. This pattern contrasts with most discussions of Mesoamerican influence on the NAS that focus on regionally atypical centers of foreign goods consumption or evidence of foreign religious traditions in distant localities. By recentering on local contexts where cultural amalgamation is expected but minimal, we raise important questions about why more distant groups found Mesoamerican societies to be worthy of emulation. The results suggest researchers should devote equal attention to cases in which distinct identities are erased or suppressed as they do to cases in which social boundaries are maintained or created anew.

The Archaic period in the Maya region represents six millennia (7000-1000 BCE) when non-ceramic-using peoples began to experiment with domesticates and reduce their settlement ranges. The single longest epoch of the Mesoamerican chronology, these early millennia are often overshadowed by the investigation of more recent peoples who built cities and have left evidence of elaborate artistic traditions. The Belize Archaic Project (BAP) began work over 20 years ago after the fortuitous discovery of aceramic deposits containing heavily patinated lithic tools and debitage under Postclassic settlements in the Freshwater Creek drainage of northern Belize. The 2019 field season marks a renewed phase of this project and initiates a program of systematic settlement survey and test excavations. This paper presents initial results of a systematic program of auguring that documented 87 Archaic-period sites and excavations at four of these locales during the summer of 2019. The renewed BAP investigates local land use patterns and foraging adaptation as well as the dynamic manner in which they affect (and are impacted by) climate change and evolving local forest and lacustrine ecology.more » « less

Did human culture arise through an evolutionary transition in individuality (ETI)? To address this question, we examine the steps of biological ETIs to see how they could apply to the evolution of human culture. For concreteness, we illustrate the ETI stages using a well-studied example, the evolution of multicellularity in the volvocine algae. We then consider how those stages could apply to a cultural transition involving integrated groups of cultural traditions and the hominins that create and transmit traditions. We focus primarily on the early Pleistocene and examine hominin carnivory and the cultural change from Oldowan to Acheulean technology. We use Pan behaviour as an outgroup comparison. We summarize the important similarities and differences we find between ETI stages in the biological and cultural realms. As we are not cultural anthropologists, we may overlook or be mistaken in the processes we associate with each step. We hope that by clearly describing these steps to individuality and illustrating them with cultural principles and processes, other researchers may build upon our initial exercise. Our analysis supports the hypothesis that human culture has undergone an ETI beginning with a Pan -like ancestor, continuing during the Pleistocene, and culminating in modern human culture. This article is part of the theme issue ‘Human socio-cultural evolution in light of evolutionary transitions’.more » « less

Abstract Our study situates the classic period center Matacanela, located in southern Veracruz, Mexico, within the context of shifting regional political‐economic systems. Specifically, we assess the potential for utilizing neutron activation analysis (NAA) of pottery in the study of changing interactions through a focus on three ceramic wares: Coarse Orange, Fine Orange, and Coarse Brown. NAA identified four compositional groups, suggesting that Matacanela selectively utilized ceramics from a variety of sources, but the center's inhabitants overwhelming used ceramics that were only occasionally exploited by their contemporaries in the nearby Catemaco and Tepango valleys. Instead, the center's primary ceramic exchange partners were in the southern Tuxtlas foothills. This divergent pattern of ceramic exchange parallels earlier obsidian exploitation differences that revealed participation in the networks of the western Tuxtla uplands as well as the southern foothills and centers within eastern Olman. The findings of this study contribute to (1) the geological characterization of ceramic resources used by ancient Gulf lowland societies, (2) to the comparative ceramic database in a region that was an important nexus for diverse cultural traditions spanning Mesoamerican prehistory, and (3) the refinement of our knowledge relevant to the divergent strategies employed by groups.more » « less

Abstract Pre-hispanic ballgames have an extensive temporal depth and geographical breadth across Mesoamerica, with over 1,500 ball courts recorded on 1,200 archaeological sites in Mexico alone. It is likely that ballgames played critical but variable roles in how communities related to each other. Most interpretations emphasize ballgames as cosmological rituals and legitimation practices exclusive to elites, perhaps often overlooking the more mundane sociopolitical processes and reasons why they carried such critical meaning for people of all classes and statuses. Ethnographic research on modern ballgames played by Indigenous and mestizo communities today can helpfully provide some insights or maybe deeper understandings into ancient ballgame practices and their relation to Mesoamerican communities. While modern games are not isomorphic with the ancient games, the duration of these traditions underscores their continuing importance and their relativity to current research. In this article I present the results of an ethnographic study of the modern ballgame pelota mixteca de hule (Mixtec rubber ballgame) in the southern Mexican state of Oaxaca. Considering the results from the ethnographic data, I then discuss an archaeological case study in the Nejapa Valley of southeastern Oaxaca where numerous ballcourts were recently documented over the past decade.more » « less
