Excellent concept, I like where this is going. It gives me more inspiration to carry out more research for my Nyoongar Timeline "Bujar Ka Nyitini" (Land of the Dreaming)
I just searched for that... is it just in the thread
here, or is there something more recent?
Looking over your timeline, by the way, it looks quite interesting, but there are some stretches with the proposed domesticated crops. You've suggested native millet (Panicum decompositum), spinifex (various species of Triodia), and wattles (Acacia). The problem is that none of these will get an agricultural civilization going. Native millet and spinifex may not even be domesticable (see below). Wattles are domesticable, but they are not a founder crop.
What Australia is actually lacking in OTL is a founder crop or crops. There are domesticable plants, lots of them, but not ones which are suitable to make the transition from hunter-gather to full-time agriculturalists. Jared Diamond notwithstanding, there are lots of domesticable plants around the world (including in Australia); he considerably underestimated the effects of selective breeding. But there is a shortage of founder crops around the world. Australia has no suitable founder crops, or at least it only has crops which would take a
very long time to domesticate. (Aboriginal peoples made a lot of use of native plants, and none of those plants were even close to being domesticated.) The PoD for Lands of Red and Gold actually is that Australia has a founder crop - red yams - which lets people get established in a sedentary lifestyle,
and get more used to systematic agriculture and selective breeding of plants. Only then can they turn to the harder to domesticate plants like wattles, murnong, and so on.
In terms of the two crops you mentioned, native millet is actually quite bad as a suitable founder crop, or even as a domesticated crop for human use. It was one of the cereal crops which Jared Diamond looked at in terms of Australian plants, and he correctly cited it as being extremely difficult to work with. There are several problems with it. The main one is that the seeds are extremely small and thus labour-intensive to cultivate. Even wattleseeds are larger, and wattleseeds are on the small side for cultivation as it is. The other problem is that the areas where native millet grows are the desert regions, which is a considerable disincentive.
Native millet would work well as a pasture crop, by the way, with the seeds being a bonus rather than the main purpose. But it doesn't work very well as a human staple. The same thing applies to other Australian cereal crops like Australian sorghum; good for grazers, not much good for people. They might even end up being domesticated for use with domesticated animals if Australia has any (emus, most likely). But they wouldn't really be much use for human consumption.
Spinifex is a very poor domesticable crop since it is very, very slow-growing. It's hard to base an agricultural society on a crop like that. It's also sensitive to a lot of soil conditions (although it does tolerate drought).
And as an aside, it's often hard to pick which plants would be suitable founder crops. There are two domesticated species of rice used today, an Asian and an African variety. Although both have been domesticated, African rice doesn't seem to have been a founder crop. Farmers had been living alongside it for thousands of years using other crops (including yams) before African rice was domesticated (2-3000 years ago). Even the Asian version seems to have been domesticated as a founder crop in India, but not in China, where other plants were used as founder crops (including some millets).
You have crops which have decent yields if selectively bred as well many are drought-resistant and hardy to craptacular soil that most parts of Australia have. There is one that comes to mind, Native Millet, with more abundant rain and a large population available to cultivate, I think it would be a major continental crop. The problem is getting out of its normal range which is in the Central Desert.
As per above, Australian cereal crops, including above, are pretty craptacular, for the most part. Root crops and pseudocereals are probably the way to go. The core of the *Aboriginal agricultural package in Lands of Red and Gold is red yams, half a dozen species of wattles, murnong (also called yam daisies), and later sweet potato.
In Western Australia, murnong will probably be replaced by some of the native tuber species - WA has an extraordinary variety of such species. There has been some serious work recently on domesticating some of these species. There is one extremely promising species, Ipomoea costata (a kind of morning glory). A preliminary plantation of this plant yielded 24 tonnes per hectare, which is a
huge yield. The problem is that this particular species grows only in the northern reaches of Australia. But there are other root crops which may be used in WA.
I'm also curious as to how the Iron Age and subsequent ages will change the Aborigines, will they even maintain recognisable cultural characteristics of their OTL counterparts. Moving from a Hunter-Gatherer lifestyle to a more sedentary one will create some unimaginable changes.
There will be all sorts of changes, but a few things will be maintained. I'll be working with OTL beliefs as a starting point, then extrapolating how they might change based on similar trends in various societies around the world. Plus a few random things thrown in on the basis that not everything is easily predictable.
Ooh, I'm curious as to what Maori culture is going to be like in TTL. I'm hoping for the existence of a formal state structure, well-developed regionally specialized agriculture, and generally a level of organization similar to that of the Inca. That would make it possible for New Zealand to become the southern hemisphere's analog to Japan once European technology is introduced.
Maori technology is going to be considerably more advanced than in OTL, due to higher population density and more stable agriculture. There are some deucedly difficult problems about turning it into a Meiji analogue, though. The Maori started from a preliterate stone age hunter-gardener society with one crop species barely suited to their homeland, in about 1280. Going from that to being strong enough to pull a Meiji in six centuries maximum is rather a stretch. Even political unity is probably optimistic.
Aw, too bad. I too was hoping to see domesticated diprotodons. But if it's not plausible, nothing anyone can do about it. Now, what about domesticated wombats? They could fill the same niche as rabbits in Europe, or perhaps with a gradual selection of the larger specimens, become an analog to sheep.
Wombats are wonderful animal, but domesticable they probably are not. Solitary, temperamental, react aggressively to things perceived as intruders (including people, I suspect), nocturnal, burrowing (equals hard to keep enclosed), and so on. They are also devillishly difficult to breed in captivity; despite lots of efforts, there hasn't been much success. Entertaining although the idea is, it stretches plausibility too far for my liking. I suspect that emus are the way to go, in terms of domesticated animals. As emu farmers around the world are demonstrating, they can be kept in captivity and bred quite easily. They do have a couple of problems in terms of diet and environment (they need some grains, and need to be allowed to exercise), but nothing which can't be overcome.
Well over several millenia, I guess selective breeding could cause Wombats to grow to great sizes. I know some larger specimens (males) can grow up to about 50 kilos in weight.
I didn't think that wombats got quite that big, but it isn't really size that's the problem. It's their aggressiveness and reluctance to breed in captivity.
As for the Maori, I'm not sure if a proper state structure could evolve unless more crops are brought into NZ to sustain a larger population , though I guess there already did exist a codified legal system to a degrees (orally transmitted albeit). The population was too sparse, for a centralised government to control anyway.
A higher population density would probably help there. The Maori population started quite a dramatic explosion when Europeans brought the first potatoes. Red yams and wattles would make for a similar growth in population.
Also having a Maori script would be much more helpful.
It would, although I'm not sure about how likely literacy is likely to develop. Most writing systems which developed natively (of which there are only a handful) seem to have had long development periods, measured in thousands of years. I'm not even sure whether the *Aboriginals will develop a full written script. Still, they could always be inspired by stimulus diffusion. A lot of cultures developed their own written scripts once they got the
idea of writing from someone else. The Cherokee script, to name just one. The Maori may be similarly inspired.
