Drift voyages across the mid-Atlantic
Pre-Columbian transoceanic contacts have long been controversial. The controversy stems from the fact that those supporting arguments for such crossings have often not evaluated the evidence as critically as was necessary. On the other hand, those dismissing these arguments have frequently ignored the inevitability of such events over long periods of time. One aspect of these debates that is seldom evaluated is the likelihood of vessels, with or …
From west to east
The prime movers behind the prehistoric colonization of Remote Oceania, and in particular the large c. 2000-year temporal gap (i.e. ‘long pause’) seen between West and East Polynesia, has long been major point of interest in the Pacific. To address these events and the processes that may have led to the known chronological disparity of these diasporas, we present results from two different, but equally powerful, analytical tools which are used to…
Estimating trajectories of colonisation to the Mariana Islands, western Pacific
The colonisation of the Pacific islands represents one of the major achievements of early human societies and has attracted much attention from archaeologists and historical linguists. Determining the pattern and chronology of colonisation remains a challenge, as new discoveries continue to push back dates of earliest settlement. The length and direction of the colonising voyages has also led to lively debate seeking to trace languages and artefa…

Prehistoric trade between Ecuador and West Mexico
The author studies prehistoric sea travel along the coast between West Mexico and Ecuador using a computer simulation incorporating the performance characteristics of sailing rafts. The model predicts that while northward voyages may have taken as little as two months, southward voyages would have entailed at least five months and may have required a strategy that took the rafts offshore for as long as a month
Ceramic Age Seafaring and Interaction Potential in the Antilles
Analysis of The fluoride Content of Human remains From the Gray site, Saskatchewan
The paper describes a method for sequencing osteological recoveries using F-/P2O5 ratios. The method is applied to a sample of 101 individuals from the Gray site cemetery, southern Saskatchewan. The results, coupled with 14C dates, provide a seriation which may be used to choose future radiocarbon samples, to assess apparent hiatuses in the use of the site, to analyze morphological variation in the skeletal material over time, and to assess the p…
