Grammar analysis reveals ancient language tree
It's not the words, it's how you use them that counts.
The languages used in Papua New Guinea have few common words, making it hard to determine their origins.
When it comes to working out the relationships between ancient languages, grammar is more enlightening than vocabulary, scientists say.
There are some 300 language families in the world today. Researchers have long studied similarities between the words in different languages to try to work out how they are related. But the rate of change in languages means that this method really only works back to 10,000 years ago.
Homo sapiens evolved more than a hundred thousand years ago and by 10,000 years ago had already settled around the globe. So researchers are keen to peer further back in time to see how language evolved and spread.
To do this, Michael Dunn and colleagues at the Max Planck Institute for Psycholinguistics in Germany decided to look at grammar.
They took Papuan languages of people in the South Pacific as their challenge. Radiocarbon dating shows humans lived more than 35,000 years ago in Melanesia, a group of islands including Papua New Guinea. But the 23 languages that have evolved in this area share few, if any, common words. So the standard techniques cannot reveal much about the languages' histories.
The researchers made a database of 125 grammatical features in 15 Papuan languages. This included how word types, such as nouns and verbs, are ordered in a sentence, and whether nouns have a gender, as they do in languages such as German and French.
As a test case, the team did the same for 16 Austronesian languages - the languages of the Philippines, Indonesia and Southeast Asia - for which vocabulary analysis has already revealed evolutionary roots.
A computer program then analysed the data to determine ancestral language links. This produced up to 10,000 possible family trees and a 'consensus tree' that best fitted the data, the team reports in Science1.
The consensus tree for the Austronesian languages closely fitted the accepted lineage from previous study of vocabulary, which demonstrated the validity of the method. The consensus tree for the Papuan languages then revealed previously unknown relationships between those languages. The people of the Solomon Islands and Bougainville Island, for example, seem to be related in language. Perhaps these people were living in one community on a common land mass more than 10,000 years ago, the researchers suggest.
The tree will need further work before it can be validated, the researchers say. The team's next step is to apply this method to old languages in the Amazon.
That would be Sundaland before the end of the Ice Age.
Sundaland is an area around Indonesia that is twice the size of present day India that went underwater from Ice Age melt.
Thanks to 'Right Wing Professor' for this post.
Heck, I can't understand (and usually don't want to) people from Massachusetts, so it's not surprising that languages are so diverse.

Who came up with that name? I'd call it "Sundawater".
I live within sight of glaciers from the last dang Ice Age.
Sundaland sounds like it may be a good place to move to if the glaciers fill my valley again.
I'll betcha that underwater property is cheap like borscht!
BTW, thanks for all your interesting posts.
Sundaland is where the Mackems live next to Newcastle and the Geordies
I found a cute t-shirt at AnimeBoston this year. It reads "English does not borrow from other languages. English follows other languages down dark alleys, knocks them down, and goes through their pockets for loose grammar." I got it for our #1 son, an English major who is finishing Law School this year.

By the way, if it weren't for Latin-educated academics who couldn't bear to use anglicized Latin words rather than properly declined Latin words and couldn't write an English grammer without claiming that you shouldn't split your infinitives, well, because you just can't do that in Latin, we wouldn't have mugged Latin for it's grammar. Instead, we'd be happily talking about indexes, datums, genuses, and so on without Latin grammar pedants telling us it's improper.
We only ended up having to write three compositions that summer, and he made sure we didn't fill it up with what he called "Easter Vocabulary"; words we never used, but put in papers to make it sound fancy.
Poing. Both science-related, and appropriate for the evolution list (languages evolve from common roots, and the kind of analysis done on these languages uses the same principles as DNA analysis which determines biology phylogenies).
