A
Model-based Age Estimate for Polynesian Colonization of Hawai`i
A model-based Bayesian calibration using 14C data from
paleoenvironmental cores and materials introduced to the islands by
Polynesian colonists estimates that the islands were likely colonized
sometime late in the first millennium AD. Two calibrations, one using
14,C dates on floral materials and the other using 14C
dates on floral and faunal materials, indicate that archaeological
materials yield relatively imprecise estimates of the colonization
event with 95% highest posterior density regions 3-5 centuries long.
Materials introduced to the islands by Polynesians date to two
periods, one that coincides with the colonization event, and another
some 3-6 centuries later. A possible disparity between colonization
and the first reliably dated archaeological evidence of human activity
is identified and estimated to be 1-4 centuries long.
Social
Transformation in Old Hawai`i: A Bottom-up Approach
An argument for augmenting the usual top-down approach to traditional
Hawaiian history with a bottom-up approach published in American
Antiquity recently. Hypothesizes that changes
in social organization are responsible for the import of poor-quality
oven stones on the Waimanalo plain and for a decline in the proportion
of tree wood charcoal in firepits over time. The paper relies heavily
on the work of Mike Desilets and Gail Murakami.
A Manual
for the Identification of Fish Remains
Alan Ziegler's fish bone reference collection and Bishop Museum's
collection of fish otoliths are the basis for this manual authored by Tom Dye
and Ken Longenecker and published by the Society for Hawaiian
Archaeology. This is the full manual, not the truncated version
available on the Society for Hawaiian Archaeology web site.
Land Snail
Extinctions at Kalaeloa, O`ahu
This paper was written with Dave Tuggle after he came to the
conclusion that Polynesians hadn't driven land snails to extinction at
Kalaeloa. The paper was originally published in Pacific
Science, then was reworked for the journal Internet
Archaeology. The Internet Archaeology version includes
interactive data analyses and graphics; the reader can download the
data on which the paper is based, recreate the graphs published in the
paper, and carry out alternative analyses. This requires that
Lisp-Stat, a freely available software package that runs on most
operating systems, be installed on the reader's computer.
Unfortunately, the Lisp-Stat user base, which probably never numbered
among its faithful more than a handful of archaeologists (probably
fewer), is now declining. Even more unfortunately, Internet
Archaeology, which used to be freely accessible, now requires a
subscription. Thus, the Internet Archaeology paper, and its
attempt to provide convenient and unfettered access to the primary
data of archaeology, is becoming obsolete and difficult to find.
Effects of
14C Sample Selection in Archaeology: An Example From Hawai`i
This is a preprint of an article published in Radiocarbon. It
illustrates the effect of careless archaeology on the dating record of
old Hawaii. Dating samples that haven't been selected for short-lived
species can add up to 1,000 years to the age of the sample.
Inattention to sample provenience, i.e. dating materials that can't be
confidently associated with human activity, can add several hundred
years to the age of a sample. These sources of error are huge
compared to the short span of prehistoric time in Hawai`i. Failure to
control for them, still a common practice in Hawai`i, makes it
virtually impossible to distinguish between interesting hypotheses
about what happened in the past.
How to Fix the
Inventory Survey Rule
These brief comments argue that it is in the public interest for the
Society for Hawaiian Archaeology to debate changes in the Hawai`i
State Historic Preservation Division inventory survey rule. Two
fundamental changes to the rule are proposed. First, strip
the rule of its preoccupation with site function so that a greater
proportion of archaeological energy and funds can be spent on data
recovery investigations. Second, rewrite the rule so that it does
not prescribe archaeological practice per se; this is necessary if
Hawaiian archaeology is going to track progress in the discipline as a
whole. These changes will simplify the inventory survey rule
and strengthen the role of research in archaeological work.
The Age of the O18
Site
A paper co-authored with Jeffrey Pantaleo and published in Archaeology
in Oceania. On current evidence, the O18 site was established more
than 200 years after O`ahu Island was first settled by Polynesians.
