The early human diet is a topic of great interest to those curious about our evolutionary past. The foods eaten by our ancestors can tell us a lot about their lifestyles and environments. For instance, the inclusion of meat in the diet was a turning point in human evolution, providing the energy required to develop and sustain an active lifestyle and a larger brain. In this context, it is intriguing to learn about the diet of early humans in Australia, who may have arrived on the continent as early as 60,000 years ago.

What You'll Learn
Early humans in Australia ate meat and vegetables
Early humans in Australia, the ancestors of modern Aboriginal peoples, arrived on the continent between 50,000 and 65,000 years ago. At this time, early humans ate meat and vegetables, with their diet consisting mainly of low-nutrient plant material. The inclusion of meat in the human diet, which occurred about two million years ago, was a turning point in human evolution. Meat provided early humans with more proteins and fats, enabling them to develop a more active lifestyle and larger brains.
The chance of prehistoric food remains surviving depends on the type of food. Bones and shells, for example, are more likely to be preserved than vegetable matter, which tends to decay more easily. In the case of early humans in Australia, stone tools, bone fish hooks, and other artefacts made from hard materials provide evidence of their diet.
In central Australia, early humans commonly ate witchetty grubs, the larvae of several species of moth found in the roots of certain shrubs and trees. They also consumed Bogong Moths, which were ground into a paste between stones. In other parts of Australia, early humans constructed fish and eel traps in creeks and rivers, and they also hunted fish, kangaroos, wallabies, bandicoots, possums, lizards, birds, and other animals with spears, boomerangs, and stone axes.
Along the ocean shorelines, early humans in Australia also ate shellfish and crustaceans. They harvested wild millet, processing the grass by grinding seeds to produce flour and also eating poisonous cycad nuts after leaching them in running water or through fermentation. The practice of "firestick farming", or burning the undergrowth, may have contributed to the extinction of some megafauna species by reducing their food sources.

They used stone tools to hunt animals and prepare food
The earliest evidence of humans in Australia has been estimated to be between 48,000 and 65,000 years BP. The inclusion of meat in the human diet about two million years ago was a turning point in human evolution, providing the energy required for an active lifestyle and the development of a larger brain.
Stone tools were used by early humans in Australia to hunt animals and prepare food. These tools were made from rocks that had been smashed and broken to create a jagged edge, or by repeatedly striking a stone with another stone to remove flakes and give it a distinct shape. This type of tool is called an Oldowan tool, after the tool-making industry in the Olduvai Gorge, Kenya. Tools became more specialised over time, with more flakes being removed and their edges worked more finely. These tools belong to the Acheulean tool industry, characterised by roughly made hand-axes found at St. Acheul in France. Later, tools from the Mousterian tool industry were characterised by finely made hand-axes, blades, and points found at Le Moustier in France.
The use of stone tools by Aboriginal people in Australia has often been portrayed as a hallmark of savagery or backwardness, with the term Stone Age used to suggest that these people were primitive and had never evolved. However, stone tool technology is highly skilled, requiring knowledge of geomorphology, geology, fracture mechanics, and the thermal properties of stone. Stone tools were used for grinding seeds or grain, and this technology was used by Aboriginal people thousands of years before people in Europe or the Middle East.
The foods eaten by early humans in Australia can also be inferred from the stone tools they left behind. For example, the discovery of stone tools used for grinding seeds or grain indicates the consumption of plant-based foods, while the presence of bone fish hooks suggests a diet that included fish. In addition, the discovery of stone tools shaped into knife blades, spear points, and ax heads suggests that early humans in Australia hunted animals for food using these tools.
Overall, the use of stone tools played a significant role in the survival and lifestyle of early humans in Australia, enabling them to hunt animals and prepare food to meet their dietary needs.

They ate insects, such as moths and moth larvae
The diet of early humans in Australia has been a subject of interest for archaeologists and anthropologists. While there is evidence of early human habitation in Australia, the specific foods they consumed may vary based on the region and the availability of resources.
One interesting aspect of early human diets in Australia is the inclusion of insects, specifically moths and moth larvae. Indigenous Australians have a long history of consuming moths, and this practice has been recently revived with the Bogong Moth Festival, or Ngan Girra Festival. This festival celebrates a tradition that dates back thousands of years.
The discovery of an ancient grindstone at Cloggs Cave in eastern Victoria provides concrete evidence of this practice. The grindstone, dated to between 1,600 and 2,100 years ago, contained collagen and protein remains from Bogong moths. This discovery aligns with Indigenous oral traditions and provides valuable insights into the dietary habits of early humans in Australia.
Moths and moth larvae were not only a source of nutrition but also played a cultural role. The harvesting and cooking of moths brought different Indigenous societies together for ceremonies and festivals. This sense of community and shared tradition is an important aspect of early human culture in Australia.
Additionally, the consumption of insects, including moths, has been a widespread practice among human communities worldwide, including in Central and South America, Africa, Asia, and other parts of Australia and New Zealand. Insects provide a good source of protein and can be prepared in various ways, such as roasting or incorporating them into cakes or pastes.

They ate fish, shellfish, and crustaceans
Early humans in Australia, the ancestors of modern Aboriginal peoples, arrived on the continent between 50,000 and 65,000 years ago. They ate fish, shellfish, and crustaceans, which were abundant in the coastal areas.
The inclusion of meat in the diet was a turning point in human evolution, providing essential proteins and fats that supported the development of a larger brain and a more active lifestyle. Fish and shellfish, in particular, are rich sources of docosahexaenoic acid (DHA) and arachidonic acid (AA), which are essential for the development of the mammalian nervous system. This would have contributed to the cognitive development of early humans in Australia.
Aboriginal Australians living in coastal areas, such as Sydney, collected and consumed a variety of shellfish and crustaceans. Both men and women participated in collecting shellfish by hand from rock platforms and the sandy and muddy intertidal shorelines of the coast and estuaries. Oysters, mussels, cockles, and limpets were commonly consumed, and specific local names were given to certain shellfish varieties.
Excavations have also revealed the consumption of crayfish, caught using small hoop nets in Port Jackson. Other crustaceans, such as crabs, prawns, and barnacles, may have been part of their diet, but there is limited archaeological evidence due to the fragile nature of their exoskeletons.
The availability of fish, shellfish, and crustaceans in coastal areas provided early humans in Australia with a valuable source of nutrition and contributed to their survival and cognitive development.

They gathered wild millet and processed it to make flour
The diet of early humans in Australia is inferred from archaeological evidence, such as stone tools, rock art, shell middens, and human skeletal remains. While vegetable matter is less likely to be preserved, the remains of shellfish, crabs, and fish have been discovered, indicating their inclusion in the diet of early Australians.
Early humans in Australia are believed to be the ancestors of modern Aboriginal peoples, with evidence of their presence dating back to around 50,000-65,000 years ago. The processing of wild millet into flour is a traditional practice that may have been adopted by these early humans.
Wild millet, a resilient grain that can grow in gravel, cracks in sidewalks, and under bird nests, was likely readily available to early humans in Australia. To process wild millet into flour, the following steps can be taken:
First, gather the wild millet grains, taking advantage of their abundance in the environment. Then, using a high-speed blender, process the millet in small batches to avoid overworking the blender's motor. Blend the millet on high speed for 30 seconds, scrape down the sides, and blend for another 30 seconds. Repeat this process a few times until a fine flour consistency is achieved.
After blending, use a fine-mesh sieve to sift the ground millet and filter out any larger pieces that were not adequately ground. Return these larger pieces to the blender and blend again until they are finely ground. Finally, store the homemade millet flour in an airtight container. This flour can be used as a gluten-free substitute in baking, bread-making, or for other culinary purposes.
By gathering and processing wild millet, early humans in Australia would have had access to a nutritious flour that could be used in various ways to supplement their diet.
