Phylogenetic methods have revolutionised evolutionary biology and have recently been applied to studies of linguistic and cultural evolution. However, the basic comparative data on the languages of the world required for these analyses is often widely dispersed in hard to obtain sources. Here we outline how our Austronesian Basic Vocabulary Database (ABVD) helps remedy this situation by collating wordlists from over 500 languages into one web-accessible database. We describe the technology underlying the ABVD and discuss the benefi ts that an evolutionary bioinformatic approach can provide. These include facilitating computational comparative linguistic research, answering questions about human prehistory, enabling syntheses with genetic data, and safe-guarding fragile linguistic information.

It is widely assumed that modern hunter-gatherer societies lived until very recently in isolation from food-producing societies and states and practiced neither cultivation, pastoralism, nor trade. This paper brings together data suggesting a very different model of middle to late Holocene hunter-gatherer economy. It is argued that such foraging groups were heavily dependent upon both trade with food-producing populations and part-time cultivation or pastoralism. Recent publications on a number of hunter-gather societies establish that the symbiosis and desultory food production observed among them today are neither recent nor anomalous but represent an economy practiced by most hunter-gatherers for many hundreds, if not thousands, of years. Psychological and political reasons for Westerners' attachment to the myth of the "Savage Other" are discussed.

The Austronesian comparative dictionary (ACD) is an open-access online resource that currently (June 2013) includes 4,837 sets of reconstructions for nine hierarchically ordered protolanguages. Of these, 3,805 sets consist of single bases, and the remaining 1,032 sets contain 1,032 bases plus 1,781 derivatives, including affixed forms, reduplications, and compounds. Historical inferences are based on material drawn from more than 700 attested languages, some of which are cited only sparingly, while others appear in over 1,500 entries. In addition to its main features, the ACD contains supplementary sections on widely distributed loanwords that could potentially lead to erroneous protoforms, submorphemic “roots,” and “noise” (in the information-theoretic sense of random lexical similarity that arises from historically independent processes). Although the matter is difficult to judge, the ACD, which prints out to somewhat over 3,000 single-spaced pages, now appears to be about half complete.

A number of well-documented sound changes in Austronesian languages do not appear to be either phonetically or phonologically motivated. Although it is possible that some of these changes involved intermediate steps for which we have no direct documentation, the assumption that this was always the case appears arbitrary, and is in violation of Occam's Razor. These data thus raise the question whether sound change must be phonetically motivated, as assumed by the Neogrammarians, or even linguistically motivated, as assumed by virtually all working historical linguists.
