Final answer:

Evidence such as butchering marks on bones, the use of fire for cooking, and changes in Homo erectus anatomy, such as increased brain size and adaptations suited for hunting, support the idea that Homo erectus consumed meat regularly and acquired it through hunting strategies.

Step-by-step explanation:

There is significant evidence to suggest that Homo erectus consumed meat on a regular basis. Findings from a specimen known as KNM ER 1808 indicated the consumption of carnivore liver, suggesting a shift to increased meat consumption. Additionally, characteristics of Homo erectus such as longer legs point to efficient walking and the potential for effective hunting, indicating a means by which meat was likely acquired.

Homo erectus is also associated with the use of fire, dated to about 1.7-2.0 million years ago. Archaeological sites have produced findings such as ancient hearths, charcoal, and charred bones, especially at Zhoukoudian, China, providing further evidence that Homo erectus was cooking meat. Furthermore, the development of tools like spears and the evidence of butchering marks on bones also indicate sophisticated hunting strategies and meat consumption.

The increase in brain size and changes in skull and teeth structures among Homo erectus are correlated with dietary changes, including increased consumption of high-quality nutritious foods such as meat. Over time, diminished prognathism, smaller jaws, and reduced tooth size are considered indicators that softer, cooked foods, including meats, became more prevalent in their diet, further supporting the idea of regular meat eating.
