Yes, the evidence from prehistoric cave paintings, along with archaeological findings, does suggest that early humans relied heavily on meat from hunting animals. These paintings often depict scenes of humans hunting large game animals, which were a major part of their diet. There’s limited evidence, if any, showing people foraging for or consuming raw vegetables or salads, and this has led to the idea that animal foods were the primary source of nutrition for early humans.

Here’s a more detailed look at the historical context:

===== 1. Hunter-Gatherer Diets: Emphasis on Meat =====
* Prehistoric humans, particularly those from the Paleolithic period, are believed to have been primarily hunter-gatherers. Their diets would have varied depending on geographic location, but hunting animals for meat was a significant part of their survival.
* Meat from hunted animals was nutrient-dense, providing essential proteins, fats, vitamins (like B12), and minerals. This made it a reliable and efficient source of nutrition, especially in harsh environments where plant foods were less available.
* Large game animals like mammoths, deer, and bison were prized because they provided large amounts of calories and fats, which were essential for energy, especially in colder climates.

===== 2. The Role of Vegetables and Grains =====
* While early humans did gather plant-based foods (fruits, roots, tubers, and nuts), it’s widely believed that meat was a preferred and primary source of sustenance whenever available.
* The foraging of plant foods, including vegetables and grains, likely played a supplemental role in their diet, providing additional nutrients and calories when animal sources were scarce or during seasonal shifts. For example, in colder climates or during winter months, hunting would have been more difficult, so people may have turned to stored plant foods or foraged for roots and berries.
* Grains (e.g., wild grasses) weren’t a significant part of early human diets until the Neolithic Revolution, when humans transitioned to agriculture around 10,000 years ago. This shift led to the cultivation of grains like wheat and barley, but before this, grains were not a primary source of food for hunter-gatherers.

===== 3. Grains and Vegetables as Survival Foods =====
* There is strong evidence that early humans turned to plant-based foods, including grains and wild vegetables, during times of scarcity or when hunting was unsuccessful. In this sense, plant foods may have been more of a fallback or survival strategy, ensuring that early humans could survive during lean times when animal protein was not readily available.
* Agriculture and the domestication of plants marked a significant shift in human history, but even in early agricultural societies, meat continued to be a highly valued and sought-after resource. Many of the earliest farming societies supplemented their grain-based diets with whatever animal products they could acquire through hunting or herding.

===== 4. Meat and Human Evolution =====
* From an evolutionary perspective, the consumption of meat played a critical role in the development of the human brain. Meat, with its concentrated sources of energy, protein, and fats, likely contributed to the increase in brain size (encephalization) in early humans.
* The introduction of cooking, especially of meat, further increased the digestibility and nutrient availability of food. Cooked meat provides more calories and is easier to digest compared to raw vegetables or plants, which may have been difficult to process given the limited digestive capacity of early humans for high-fiber plant material.

===== 5. Raw Vegetables and Modern Agriculture =====
* The emphasis on raw vegetables and salads in modern diets is a relatively recent development. While humans have always consumed plants, the cultivation of tender leafy vegetables that are commonly eaten raw (like lettuce, spinach, and other salad greens) became more widespread with the rise of agriculture and settled societies.
* In the prehistoric context, raw vegetables would have been harder to digest, and the human digestive system is not as well adapted to breaking down tough plant fibers compared to herbivores. This reinforces the idea that humans primarily relied on meat for nutrition when available.

===== Conclusion =====

Yes, the historical and archaeological evidence suggests that early humans relied on meat as a primary food source, with grains and vegetables playing a secondary role, likely for survival or during times when animal foods were unavailable. The focus on hunting large game is well-documented in cave paintings, and plant-based foods were likely gathered opportunistically.

The shift toward grains and vegetables as staples of human diets came much later with the advent of agriculture, but even then, animal products continued to be highly prized for their nutrient density. So, from a historical and evolutionary perspective, the idea that humans evolved primarily as meat-eaters with plant foods as supplemental sources of nutrition holds true.
