Just like with biological species, the moment when the last (or even last few members) die is just a symbolic event, most of the diversity is lost much earlier. (It is a small subset of language/folklore/traditions/etc. one person can keep in their head, just as one individual carries just a small part of the genetic diversity of the species).
"Languages in the Andamans are thought to originate from Africa. Some may be 70,000 years old."
Wow - I wouldn't mind a linguist vetting that claim. How would we even know that a language hasn't evolved enough to become an entirely different language in over ten times the length of recorded human history?
That claim is utterly bogus. There's no indication that the languages have anything in particular to do with Africa, and indeed, no evidence that the language has 'evolved' more or less than any other. There is nothing unique to Andamanese languages to support the rapidly multiplying claims that they're 'ancient' or 'neolithic'. They're just isolated.
There have been some attempts to study language drift over time and geography. The proponent that springs to mind is Joseph Greenberg. His work is an attempt to work backwards to the common core of language, the starting place.
If you knew approximately how fast language changed, and you saw two related languages, you would know when they drifted apart. There are also linguistic isolates like Basque where you can't really play this trick.
This article doesn't mention any efforts that might have taken place to preserve the language, did they record her speaking it? Did she try to teach anyone else the language? etc.
I thought the same thing -- if this is such a big deal, did they try to preserve the language by having someone else learn it? I would have liked it if they at least commented on this; maybe there's a good reason they weren't able to.
The picture with the subtitle "Professor Abbi and Boa Sr became firm friends" is rather striking evidence of the diversity of human types present in that area of the world.
Some Google searching brings up an article with a descriptions of mitochondrial sequencing done on the Andamanese. Apparently they are of African pygmoid descent.
It's a rather good object lesson -- if you want to be a professor (the one on the right), don't let your ancestors get trapped in a genetic backwater for tens of thousands of years, missing out on all those good brain gene selection events.
EDIT: Not pygmoid after all. The pygmoid features are the product of convergent evolution. The evolutionary trend towards small stature seems to be due to resource competition from living on an island with barely enough space to support human habitation. It looks like they came through southern Asia.
