dravidian languages are not indo-european

The entire country of India doesn't speak only Dravidian languages. You can understand where the confusion comes from right? The person I was replying too didn't say Dravidian, it says Indian languages.

Sorry for my tone, I didn’t mean to come off as rude. It’s understandable why one would be confused here.

The only interesting thing I know about Aborigines is they're the only known people who didn't invent the bow and arrow. As a hobbyist archer this is fascinating to me. They apparently didn't need it, as they're still around.

It's the wood. You can rank woods by the amount of strain energy per unit of mass that they can take before breaking. The higher this figure, the better the bow, because it'll store more energy for a lower mass in the limbs before it breaks, and the differences can be fairly significant.

The best bow woods are all at the top of this list, along with a few that should be good in theory but aren't used likely for other reasons (i.e. the plant just doesn't produce the kind of limbs you need to make a bow). The best Australian woods are fairly ordinary by comparison. On average they're hopeless. This isn't to say you can't do it (people do with spotted gum, which isn't a good bow wood), just that there are better ways of going about it if you want to hunt.

I'd be surprised if northern Australians at least didn't know about the bow, because there was frequent contact with Indonesia and people from PNG, all of whom practiced archery. There are oral traditions in places like Arnhem land testifying to this contact going back generations.

More than a decade ago I submitted my DNA to the National Genographic Project [1] which was an attempt to trace ancient human migration using Y chromosome and mitochondrial DNA from a sampling of people around the world. My paternal Y-chromosome line showed an ancient mutation (>50K year ago) carried by humans who had likely spread through a coastal migration from Africa around coasts of the Arabian Sea down to South…

It might support the prescientific racial classifications, but it definitely undermines the idea of a nationally pure identity for any country. The "Aryan race" comes from the mixture of several different ancient cultures. The same can be said for north Indians, and other groups which claim to have some pure ancient genetic lineage.

Looks like this is quite old...they will probably find even more introgression. Something like 80% of Australian languages are from Indian-derived language families and developed from around the time of the Dingo introduction (only 4000 years ago), so there basically had to be a substantial amount of gene flow as well. Only a minority of the aboriginal languages come from an earlier substrate. It would be surprising…

> 80% of Australian languages are from Indian-derived language families and developed from around the time of the Dingo introduction (only 4000 years ago) Source? Australia has been continuously populated by Aboriginal people for 60,000+ years, with over 260 languages I find that claim incredibly hard to believe.

It only took 200 years for 200 of those 260 languages to be lost or brought to the edge of extinction. It's at least plausible and to me quite believable that the arrival of a group with a technological advantage 4,000 years ago could have had a substantial impact on the existing languages.

The same set of languages definitely will not have survived for 60,000 years. Tribes come and go, merge and split. Outside influences bring in new words and grammatical structures. Oral tradition is a low fidelity carrier of language and culture, and easily accommodates change in language.

They also didn't invent the wheel or build a space program

Yes, ppl in the same country have more similar genomes. But modern population genetics has found that 1. There is more similarity than difference between any 2 humans on earth (there are africans and europeans who share more dna than with others of their own ancestry. And, 2. People move around, a lot! We knew this already but there are a huge number of undocumented migrations that are being revealed by these studies. Turns out 20th century multiculturalism is just an acceleration of what we already did.

He's talking about the fact that Aboriginals, not unlike Native Americans, reject any attempt to explain their origin via science as they stick to the story of their origin that comes from their religion, and see the science based origin as disrespectful.

And I'm saying the place to have that fight is with the putative Aboriginals and not here on HN where everyone is just talking about the science. I mean, I get it. People are mean. People are unreasonable. Lots of good discussion can't happen because people are mean and unreasonable. But you're not making things better by assuming bad faith and throwing shade at everyone else preemptively. That's just being mean and…

It was very insightful for me to know that its common amongst Aboriginals there to have that view. I will corroborate it elsewhere now what I know what to look for.

I first came across this in the absolutely fascinating documentary The Journey of Man A Genetic Odyssey : https://www.youtube.com/watch?v=W_xTG6VXlIQ It is a "must watch" for everybody who really wants to understand Genetics/Migration. Also see : https://en.wikipedia.org/wiki/The_Journey_of_Man

I recommend too. This is the documentary created by Spencer Wells who led the National Genographic project. This was created using data about 15 years ago - I've been looking forward to an update that accounts for recent data.

Yes, this documentary (and the book) are far more approachable and understandable for the "common man".

No reason to say that though. The person you replied to was saying it is a shame it is an emotionally charged discussion and he is right. That one particular discussion on HN might not be emotionally charged doesn't negate his point.

Were you just pretending not to understand?

This has been known for at least a decade. https://westhunt.wordpress.com/2013/01/15/a-three-hour-tour/ >Here’s a scenario. A ship from some Indian civilization about 4000 years ago [maybe Indus] loses its way and ends up crashing on the shore of Arnhem Land. Like most ships, its crew is all male. They survive the landing, and end up warring with a local tribe. Eventually, they kill off most of the men and annex the…

> incredibly advanced, magicians or gods.

Four thousand years ago pre-dates the Bronze Age in southern India by quite a bit, so not really that advanced.
