I know that we humans still eat carnivore meat, but compared to the mainstream livestock-based diet, the carnivore-based diet is much niche. This article explores why carnivore meat is rarely eaten, and essentially explores why we humans have formed the dominant eating habits we have today.
About the food
Although human beings in some areas still struggle to ensure food and clothing, most human beings no longer need to worry about this problem, so many people's pursuit of diet is not only to eat enough, but to eat well and eat healthy. In addition to being completely vegetarian, people who eat more fruits and vegetables always have to eat some meat to supplement it, and these meats usually come from poultry and livestock, which are basically grass-fed or mixed food species.
Looking back at the history of our ancestors, we can know from a number of archaeological discoveries that human eating habits are not immutable, we have experienced the stage of eating only plant food, and we have also experienced the stage of eating only animal food, and we are not only eating herbivorous animals.
So why is there such a change in our human diet?
Why do humans rarely eat carnivores?
Reason 1: Whether it was before or now, eating the meat of carnivores is a costly thing.
Even in modern times, when humans have all kinds of hunting tools, hunting is a risky thing, let alone when our ancient ape ancestors attacked the local area with their bare hands or stone tools. At that time, our ancestors were actually one of the predators of carnivores, so the fear of carnivores was engraved into the genes of the early apes, and this fear was passed on to us.
When Australopithecus began to hunt, they had to compete with predators, hunting herbivores while being wary of predators to kill themselves. Later, the apes had mastered the art of hunting, but hunting predators was still very risky. Australopithecus hunted carnivores often in teams, and the purpose was not to eat meat, but to eliminate the threat posed by predators.
It's difficult to just hunt carnivores, let alone domesticate them as livestock. A number of archaeological studies have found that after our ancestors evolved to the stage of Homo sapiens, their diet was not much different from that of now, mainly because our ancestors already knew how to domesticate some animals for long-term meat and plant cultivation. The animals we eat now are basically good goods that our ancestors had carefully selected at that time.
The animals domesticated by humans at that time had some characteristics, first of all, they were all social and easy to manage and catch in large quantities; The second is that although their personalities are not very good, at least they are not as irritable as carnivores, and you see how docile dogs are now; Finally, they are omnivores, which is crucial, indicating that the cost of raising them is not so high, and plant feed is definitely better obtained than meat feed.
Reason 2: The higher the level of the food chain, the less energy flows.
Our ancestors came from the cruelty of nature, and they knew very well the conditions for energy transfer in the food chain. The energy on the side of the top predator is very small, after all, the food source of the predator is the bottom plants or animals, and these bottom guys are the role of "producers".
The food chain can be seen as a pyramid, the lower the level, the more nutrients and energy there is, so that they can be supplied to the upper animals, which is the basic law of the flow of energy and nutrients. Carnivores naturally understand this truth, so they rarely hunt other carnivores, because this is a thankless task, it is better to hunt herbivores in the lower ranks of the food chain, which is simple and nutritious.
Our ancestors were very wise, and they naturally understood this.
In addition, carnivores are generally not tasty, which is determined by evolution. Because carnivores need more developed muscles to hunt other animals and can't have too many other designs, they have more developed muscles than herbivores, eat more wood, have little fat, and don't have layers to eat.
Reason three: herbivores are definitely more numerous than carnivores.
In order to survive, species at the lower levels of the food chain will have higher reproductive efficiency, and only in this way can they ensure the continuation of the population, otherwise they will be eaten clean by carnivores at the upper levels of the food chain. The food of meat eaters is obtained by hunting, and naturally the food of herbivores is rare, which makes them not have much time to raise offspring, so the reproductive efficiency of meat eaters is often very low.
When our ancestors learned of this pattern, they naturally chose herbivores in large numbers, because they were more stable and could provide a continuous supply of food.
postscript
Postscript, once again, humans eat carnivores, but they are not the mainstream diet, which I believe everyone admits. Even today, there is no attempt to commercially raise carnivores for meat, except that carnivores are protected animals now, and there is also the same analysis as described above.
The experience of my ancestors is my best argument.
However, being an upper-level species in the food chain is not always very comfortable, because substances in the food chain accumulate, and when animals in the lower levels ingest harmful substances, these substances will accumulate and eventually be eaten by the upper-level species and accumulate in the body. This, in turn, may be caused by human pollution of the environment.
