Oceans, Islands, and Coasts: Current Perspectives on the Role of the Sea in Human Prehistory

ABSTRACT Archaeological studies of island and coastal societies have advanced significantly over the years. Long marginalized as relatively recent developments, coastal, maritime, and island adaptations are now recognized as having a much longer and more complex history. Consequently, the archaeology of island and coastal societies has become increasingly relevant to a variety of important anthropological and historical topics. In this paper, we discuss some current issues in island and coastal archaeology, including: (1) the antiquity of coastal adaptations and maritime migrations; (2) variations in marine or coastal productivity; (3) the development of specialized maritime technologies and capabilities; (4) underwater archaeology and drowned terrestrial landscapes; (5) cultural responses to insularity, isolation, and circumscription; (6) cultural contacts and historical processes; (7) human impacts and historical ecology in island and coastal ecosystems; and (8) the conservation and management of island and coastal sites.

Human impacts and adaptations in the Caribbean Islands: an historical ecology approach

Archaeological investigations demonstrate that peoples first settled the Caribbean islands approximately 6000–7000 years ago. At least four major, and multiple minor, migrations took place over the next millennia by peoples from Mesoamerica and South America who practised various subsistence strategies and had different levels of technology. For decades, researchers have been interested in investigating how these groups adapted to and impacted insular environments through time. This paper combines archaeological, palaeoecological, historical, and modern biological data to examine the effects of humans on Caribbean island ecosystems using a historical ecology approach. By synthesising a wide range of data sources, we take a human/nature dialectical perspective to understanding how peoples adapted to and modified their environments. The data suggest that earlier foraging/fishing Archaic groups (ca. 6000–3000 BP), who used a stone tool and shell technology and transported few, if any non-indigenous plants or animals, still impacted island landscapes as evidenced by bird and sloth extinctions. As more advanced ceramic making horticulturalists entered the Antillean chain around 2500 BP, there is an observable change to island environments as a result of forest clearance, overexploitation of both terrestrial and marine resources, and growing populations. Palaeoecological and palaeoenvironmental records also suggest, however, that an increased moisture regime during the late Holocene probably led to a decrease in near-shore salinity and heavier sediment and nutrient loads in rivers. These conditions would have been exacerbated by land clearance for agriculture, leading to coastline progradation, increased turbidity, and mangrove development resulting in changes to the availability of resources for humans on some islands. Although prehistoric peoples in the Caribbean were certainly impacting their environments, it was not until Europeans arrived and population centres grew that intensive and widespread degradation of island landscapes and resources occurred. Modern ecological studies, along with historical and archaeological data, indicate that hundreds of species have been driven to extinction or extirpation – many others have significantly diminished in number, especially within the last two millennia.

Islands of Isolation: Archaeology and the Power of Aquatic Perimeters

ABSTRACT Isolation has contributed over time to the development of humans culturally and biologically. The concept of isolation was popular in earlier anthropological and archaeological discussions of island settlement, but it has waned in favor of models emphasizing interaction. Although many islanders around the world developed sophisticated techniques for seafaring, these did not assure them of constant access to other peoples or places. Using case studies from the Pacific, we stress the importance that isolation played in island societies; the sea may have been a highway to some but for others it remained a difficulty to overcome. While we emphasize here the need to consider isolation factors in the archaeological study of islands, it is clear that we should move beyond the “isolation” versus “interaction” debate and recognize that, for varying environmental and sociocultural reasons, different levels of connections and separation existed between island peoples.

Coastal Erosion and Site Destruction on Carriacou, West Indies

Abstract Archaeological investigations on the island of Carriacou in the southern Lesser Antilles, west Indies, have revealed prehistoric sites dating from CAL A.D. 400 to 1400. Grand Bay is one of the largest and archaeologically richest sites on the island and in the region, but is rapidly succumbing to erosion from natural forces and human activities. A similar problem affects the site of Sabazan. Both sites are located on the windward east coast of the island and have been, or are currently, mined for sand; two hurricanes also occurred recently. Photographs and extensive mapping of Grand Bay and preliminary work at Sabazan indicate that both sites are eroding at an average rate of approximately 1 m per year along the lengths of their coastal profiles. These data, combined with a quantification of materials recovered from excavation at Grand Bay, indicate that the loss of cultural remains from natural and human causes is catastrophic and that these sites will likely be completely destroyed within the next two decades if erosion continues at its present rate.

Anthropogenic impacts to coral reefs in Palau, western Micronesia during the Late Holocene

The Palauan archipelago contains one of the most ecologically diverse coral reef systems in the Indo-Pacific that was as attractive for humans prehistorically as it is today. New evidence is emerging that during the past few thousand years there has been increasing exploitation of coral reef resources, particularly finfish and mollusks, leading to a decline in taxa numbers, richness, and diversity in various locales. This paper examines the historical interactions between human populations and coral reef ecologies in Palau by combining known archaeological data and results from modern biological data of different reef fauna. The integration of these data sources provides a framework for attempting to explain variations in taxa composition between islands in the archipelago and how this may relate to human exploitation or other phenomena through time. By using this perspective to link past events with present-day conditions, we can gain a better sense of the extent to which anthropogenic changes may have affected island environments in western Micronesia during the Late Holocene. The study also illustrates the many difficulties researchers face in attempting to synthesize and explain past and present human predation behavior when using disparate sources of data.

Precolumbian Settlements on Carriacou, West Indies

Abstract The first systematic archaeological investigation of Precolumbian sites on the island of Carriacou in the West Indies provides a rich source of information regarding Amerindian settlement in the southern Caribbean. Herein, we report results from an island-wide survey and subsequent excavation at two large village sites—Grand Bay and Sabazan—that provide evidence for an intensive late Ceramic Age occupation dating between CAL. A.D. 400–1200. Results from four seasons of excavation at Grand Bay and two at Sabazan indicate that inhabitants colonized the island later than larger nearby islands (although an earlier settlement is possible); were engaged in inter-island and South American interactions as evidenced through analysis of pottery, stylistic artifacts, and faunal remains; exploited a variety of marine and terrestrial foods, including several animals rarely found in the Antilles that were translocated to the island from elsewhere; and buried their dead in and around shell middens and, at least once, under a habitable structure.

Prehistoric migration in the Caribbean: past perspectives, new models and the ideal free distribution of West Indian colonization

Abstract Historically, archaeologists have pursued two basic approaches to prehistoric Caribbean colonization: those relying on historical narratives and those informed by theoretical modelling. With few exceptions, the latter have not been widely employed. Here, we introduce a behavioural ecology model used in Pacific archaeology, the ideal free distribution (IFD), to understand Caribbean migration and island settlement as a form of adaptive behaviour. We assess the sequences of Ceramic Age (post-2500 bp) colonization and overall prehistoric island colonization for fit against the predictions of the IFD using terrestrial net primary production and island area as measures of habitat suitability. We conclude that certain aspects of Caribbean colonization – the initial settlement of larger, high-quality-habitat islands and temporal pauses between migration pulses – are consistent with the IFD. Model inconsistencies observed for Ceramic Age colonization, however, are best explained in terms of the limitations of Pre-Columbian seafaring and territorial behaviour on the part of pre-existing Archaic occupants.

The Pre-Columbian Caribbean: Colonization, Population Dispersal, and Island Adaptations

Abstract Once considered a backwater of New World prehistory, the Caribbean has now emerged from the archaeological shadows as a critical region for answering a host of questions related to human population dispersal, Neotropical island adaptations, maritime subsistence, seafaring, island interaction networks, and the rise of social complexity, among many others. In this paper, I provide a review of: (1) what is currently known about the antiquity of Pre-Columbian colonization of the Caribbean using archaeological, biological, and oceanographic data; (2) how these data inform on the dispersal of what appear to be many different population movements through time; and (3) the subsequent adaptations (e.g., technological, subsistence, and economic) that took place across the islands after initial contact. Results of more than a century of research demonstrate that the Antilles were settled much earlier than once thought (ca. 7000 cal yr BP), in multiple waves that show strong linkages to South America, but possibly originated from more than one source location. Dispersal was patchy, with several intriguing chronological and spatial disparities that scholars are now investigating in more detail. Beginning ca. 2500 cal yr BP, and accelerating around 1500 cal yr BP, the frequent transport and exchange of goods, services, animals, plants, knowledge, and spiritual ideologies between the islands as well as mainland areas — particularly South America — testify to the interconnected nature of Pre-Columbian societies in the region. The use of more advanced analytical techniques, including ancient DNA, archaeobotany, stable isotopes, and various approaches to geochemical and mineralogical sourcing of artifacts, which until recently have been largely underused in the Caribbean, is opening new avenues of research that are creating exciting opportunities for examining ancient Amerindian lifeways.

Ceramic petrography and cultural interaction in Palau, Micronesia

Because of their durability and widespread use, ceramics in the Pacific are important artifacts for examining patterns of prehistoric subsistence, settlement, and societal interaction. Numerous studies demonstrate that petrographic analysis of prehistoric pottery in western Oceania can differentiate temper sands and other mineral constituents unique to geotectonically different islands. However, a detailed study of tempering agents has not been attempted for ceramic assemblages in Palau, Western Caroline Islands, Micronesia. We present the first major synthesis of Palauan ceramic petrography and petrological classification. The analysis of several sherd suites recovered from both the volcanic and limestone islands in the archipelago and other nearby western Micronesian atolls suggest that pottery was locally made, manufactured using primarily grog or composite (mixed-grog sand) tempers, and transported to smaller islands within and outside of the Palauan archipelago. The research has implications for determining raw material acquisition by ancient Palauan potters and is a critical step for developing regional models of intra- and inter-island exchange and interaction.
