Why didn't Aboriginal Australians invent agriculture?

Why didn't Aboriginal Australians invent agriculture?

They did.

Indigenous Australians were farming eels over 6000 years ago.

These traps involved building channels, dam walls, pond areas for aquaculture and cover a significant ground area (stretching over a 30km length).

Hundreds of tonnes of basalt blocks were moved to create a 200m long fish trap channel:

First reports of these channels and ponds, by government explorers in 1841, were ignored or dismissed as evidence of irrigation by an earlier, more advanced people living in Australia prior to the appearance of the Aborigines. This may have contributed to the erroneous belief that Indigenous Australians didn't invent agriculture.

Recent interest may possibly lead to eel farming, fishing and selling on a commercial basis.

How come Aboriginal Australians didn't manage to raise their civilization levels to that of other continents?

It might be a fine point but, GG&S was more about competition between civilizations rather than whether one civilization advanced or not. In fact GG&S was rather silent on scientific advanced civilizations except when it came to 3 specific technologies which became important when two civilizations clashed. Those technologies were

• how early or if they developed Guns,
• how early or if they developed steel.
• how strong their germs were
  • whether they domesticated animals, dependent upon whether animals suitable for domestication were present on their continent,
  • latitudinal width of their home continent

Aboriginal Australians likely didn't advance as fast as other civilizations because their was no pressure on them too. Australia is a big isolated place and the first Australians had abundance of water, food, game and land all wrapped up on a temperate climate. They didn't need to innovate. Didn't need to pressure themselves to survive or outcompete one another for resources or even overcome invaders.

Also they didn't benefit from other cultures innovations like civilizations which grew up proximal to other civilizations did in Eurasia. In Eurasia's community of nations one civilization invents the wheel, bronze, iron, gunpowder and it spreads to multiple civilizations through trade. Aboriginal Australians didn't benefit from such proximity.

More on GG&S
Guns Germs and Steel assembles a collections of ideas over why Britain or England rose militarily and was able to basically conquer and dominate a global empire relative to Papua New Guinea. An island about the same size as England which didn't have the same military successes. More broadly why Eurasian civilizations when they came in contact with North Central South American, African, and Australian civilizations invariable came out on top. The answer notes that diseases did the majority of the killing when such Civilizations met; Eurasia civilizations have more plentiful germs given their wide longitudinal span, and abundance of domesticated animals which lived in close proximity to the populations ( horse, ox, mule, cow etc ). That and how quickly they developed steel and gunpowder were additional factors.

A quick search reveals articles such as Evidence for Indigenous Australian Agriculture which contest the very premise of your question. There seems to be evidence of domesticated plants, and the population density of some settlements suggests that food production of the surrounding territory exceeded the level that could be expected from wild plants alone.

More to the point, agriculture is developed as a response to challenging life conditions. People don't start domesticating plants for fun, they do it because they see no other way to sustain a rising population density with existing food resources. If the problem can be solved in a different way (e.g. by expansion or through frequent conflicts reducing the population), they may forego agriculture for a long period.

One way to approach the question would be anthropological. There is a dissertation with the title, “Why Foragers Do Not Become Farmers,” which you can download for free. It's based on work done in the Philippines, which might nevertheless generalize to Australia.

It's been some years since I read the research, and the author offers a number of potential explanations. But the one that sticks in my mind was the following: since foraging for food is an uncertain business, in order for a community to survive it's necessary to share resources freely. If I find a yam, I share it automatically with whoever is around me; and I know that they will reciprocate if they find a yam. (I don't recall if this is a universal; someone may be able to correct me. But it was certainly true of his group.) So if a forager tries a new thing, and raises a field of crops... everyone s/he knows will show up expecting his/her share of the produce. So all of that work is distributed among the community. At the individual level, then, there's no real incentive to perform the laborious work of farming. It's a lot of work, and you don't get ahead in your culture.

T.E.D. answer is correct from my point of view (I also agree with Diamond theory regarding to availability of plants and animals as a must for civilized life). But, to give a little bit more context. Maybe we can divide the answer in two:

1. Domestication of crops and animals as a basic requirement for civilized life.

This is one of the pillars in Diamond theory. As far as we know, there are few examples of advanced civilization in cultures before neolithic (neolithic means that farming is developed), only Göbekli Tepe comes to my mind (to build something like that you need an organization that is not avaible in small societies of hunter/gatherers). Once farming is available, people can be sedentary. From here diversification of work is possible and social life can change. Since we're talking about a theory, and we have a single Earth, no more samples are available to confirm it.
Summary: The theory says that for civilized life you need first animals/plants domesticated. If we agree with that, we can jump to next point.

2. Availability of crops and animals suitable for domestication in Australia.

This is the main issue. As long as I know, not a single plant or animal has ever been domesticated in Australia. But this does not mean that there are not plants or animals available, after all, native australians had to eat something.
So, since nowadays edible plants are available for grow at home, the question is: Why native australians did not became farmers using those plants? Maybe this question belongs more to gardening instead of history, I only can suppose that those plants did not give enough calories in exchange of the effort required to grow them in first place.

If we agree with the first answer. Then we must search whether the second answer is correct. Even though Göbekli Tepe might be an example that is not covered by Diamond theory.

Another theory belongs to Toynbee, who says that only a challenge to the lifestyle (for example, an invasion or a climate change) causes a change in people's mind. A change in the mind of people is a must in order to change your lifestyle, to force a society to change to a sedentary style for example.
If we do not know any case of climate change in Australia at the end of last glaciar age (neolithic started after that in Eurasia), in the same fashion that happened in Eurasia, then that challenge was not present in Australia.

A proper rephrasing of the question title now is of course: why didn't Australians invent Eurasian agriculture before the Europeans came to them?

Sounds non-sensical? It is not!

The obvious answer to the frame defining title in its rephrased form is of course that they weren't Eurasians in Eurasia.

That is the effect of not properly defining "what is agriculture?"

Is it characterised by herding milk-producing livestock, just something different than living the hunter-gatherer live-style? Is it inventing the most strange idea of "land can have individual ownership"?

The provocative thesis is:
Aboriginal Australians invented agriculture before anyone else on this planet. That is arguably a more valid direct assertion than the indirect assumption informing the title question.

A hunter-gatherer goes out hunting if she is hungry or collects seeds and fruist if she is in he mood when these can be harvested. When ressources run out both move on to greener non-pastures.

And what did Australians do? Naked barbarians living from nothing but what they find and from hand to mouth?

They manipulated the landscape and the flora and fauna for their own profit. That is the exact equivalent to European harvest: making 'gathering' a more predictable thing within a smaller area to oversee. Then stockpiled this for future use. Near their houses.

We see in more detail the hallmarks of a culture and civilisation, if one goes back to universally applicable analytical definition that are not culturally dependent but operationalised.

The great advantage of Aboriginal crops is that they have been developed through seed selection, direct planting and weeding for the harsh conditions of Australia. Many of the grains grow on sand and require a minimum of irrigation. The good news is that the Rural Industries Research and Development Corporation has been studying some of these grains with a view to incorporating them in the modern agriculture of Australia.

Latz says that, ‘the nutritional value of the seeds from the desert species is equal to or better than that of the cultivated grains’.95 These indigenous plants promise a huge economic bounty for the country and our future prosperity demands they be given serious consideration.

Many early observers commented on the aesthetic proportions, tasteful positioning and social harmony of the townships. Sturt described one town as evening fell:

the natives … sat up to a late hour at their own camp, the women being employed beating the seed for cakes, between two stones, and the noise they made was exactly like the working of a loom factory. The whole encampment, with the long line of fires, looked exceedingly pretty, and the dusky figures of the natives standing by them, or moving from one hut to the other, had the effect of a fine scene in a play. At eleven all was still, and you would not have known that you were in such close contiguity to so large an assemblage of people.137

The smaller huts attached to the dwellings of this and other clans were full of stored produce. Yards attached to these store houses were used as animal holding pens. People here were not clinging on to survival in the desert; they were thriving and engaged in a rich and joyful life.

Pottery is one of the tests applied by Western archaeologists to the developmental level reached by civilisations. Australian Aboriginals would, at first glance, appear to have failed this test. The superb glazed and kiln-fired pottery of China, Greece or Rome has not been found here; however, clay vessels were made. While most were relatively crude sun-dried bowls, some were baked beside the fire; others, particularly small clay figurines, were fired on charcoal beds and some were glazed with mineral washes.

The tests applied in this way simply test how similar a group is to European and Asian civilisations and may not reflect their success in other areas such as social cohesion, resistance to warfare or sustainable use of resources. This chapter looks at elements of Australian pottery and food preservation because the perceived lack of them in Australia has been used as an indicator of social backwardness. This attitude prejudices opinion about the level of development of Aboriginal and Torres Strait Islander people. To point out that Indigenous Australia did indeed use baked clay vessels and preserved food is not an attempt to claim distinction for the First Australians, but simply to point out that if that were the only test for development it cannot be seen as completely absent from this country.

According to the earliest records, the use of clay to render houses or make storage vessels was witnessed in most parts of Australia although the crude drying and firing methods may have resulted in the remaining fragments being overlooked by later surveys. Stores of food were seen across the continent too; although most disappeared quickly, some ossified caches have been found in stone chambers, preserved by the tight fitting stone plugs.

Gerritsen suggests the storage of food surpluses is one of the indicators of agricultural nations and defines three types of food storage used in Australia: ‘caching, stockpiling and … direct storage’.

At face value it is therefore:

Q Why didn't Aboriginal Australians discover agriculture?

Because that wasn't allowed to have taken place in the grand narrative of European settlers. The Australians did discover agriculture, early and on their own, but the evidence that was available was systematically ignored.

As to what prevented 'them' from discovering "other technologies": nothing 'prevented' them. Technology gets invented and innovated upon by opportunity and necessity. That is the valid core of Diamond's hypothesis. If those two factors get low values, new technology simply isn't worth the bother.

And that seems to be the root of an egregious misreading of Diamond: That sweet grasses of Eurasia would be the great opportunity to start grain based civilisation not found elsewhere. But if you compare barley to teosinte and teff it should become clear that this is a greatly overgeneralised theory. The puny and meagre teosinte bred into impressive maize cobs shows that human ingenuity could achieve satisfactory results from the most unlikely starting point. Teff shows that the grains themselves could remain tiny, even difficult to handle from sowing to eating (teff meaning: easy to loose) and still form the staple food of a society.

Nothing in Diamond's theory affords to be used as a deterministic teleology and no such generalisable effect can be applied to Australian populations. Only in retrospect we like to find and see certain path dependencies.

One example when both factors of opportunity and necessity did came together would be hunting equipment improvements:

This is a class of question we here on History.SE called a Guns, Germs, and Steel question. This is because we get a lot of them, and even though the question details may be different, the answers to all of them are almost identical, and could be penned by anyone who has read that book. We don't have a "required reading list", but if we did, GG&S would be on it. Do yourself a favor and pick up a copy at your favorite book source.

But first off, the original title of the question implied that Native Australians weren't even at the Paleolithic level. That's egregiously wrong. The entire Genus of our species started using stone tools 3.3 million years ago. Its essentially what defines us. Native Australians were not only using stone tools (Paleolithic), but stone tipped projectiles and boats (Mesolithic).^*

The requirement for jumping from Mesolithic to Neolithic is domesticating crops and/or livestock. Obviously this depends on the availability of domesticable flora and fauna. This is where Australia poses problems. It has no native plant or animal species that humanity has found to be of any real domesticable use. To a certain extent this is understandable, as the continent is rather small compared to Eurasia or the Americas, and a huge percentage of what little it does have is desert.

It does have an interesting and unusual variety of fauna, but little of it resembles the fauna humanity has domesticated elsewhere in the world. All the large mammals humans have domesticated elsewhere are placentals within a certain small niche of behavior. There are loads of useful-looking animals humans can't domesticate (Diamond's examples are zebras and cheetahs). Only a very few species can be domesticated, and Australia had very poor luck in that regard. Their luck hasn't improved any by the importation of Europeans; all the domesticated species used in Australia today were brought in by immigrants.

^{* - If this was an honest mistake on your part, well now you know. But it happens to be one that is rather insulting to the people it describes, implying they aren't even really humans, so its a suspicious one. If someone told you this, they put you in a very awkward position by putting this idea in your head, so I'd highly suggest protecting yourself in the future by not paying attention to anything they tell you.}
