Summary:  1999 Macmillan Magazines Ltd
The pattern of human colonization of the
islands of the central and eastern Pacific
is contentious. Two models have been widely
considered: the `express train to Polynesia'
and the `entangled bank' hypotheses14
. Here
I analyse the mitochondrial DNA sequences
of the lizard Lipinia noctua, which lives
alongside humans on these Pacific islands,
with a view to distinguishing between these
two hypotheses. From a phylogenetic analy-
sis of mitochondrial DNA sequence varia-
tion, I find that these lizards colonized the
central and eastern Pacific as a result of
human-mediated dispersal, presumably as
stowaways on early Polynesian canoes. The
extreme genetic similarity between the dif-
ferent colonies indicates rapid colonization
from a single source, which I take as support
