Some have wondered why humans haven't evolved to produce venom—a biological weapon of immense and irreversible threat.
The reason is that venom is essentially a protein.
As large, warm-blooded animals, humans require a massive amount of protein to sustain life, whether for maintaining body temperature or for the evolutionarily selected development of the brain, the daily consumption of protein is enormous.
Therefore, only small, cold-blooded animals like snakes, lizards, and amphibians evolve venom glands and accompanying fangs or claws to inject or spray venom, turning excess protein into venom.
In contrast, apex predators in their respective food chains tend to evolve towards efficient and straightforward physical force—lions, tigers, bears, and the like. The highly intellectual humans even learned to enchant their tools with venom, avoiding the heavy toll on their bodies.
But this does not apply to Jiang Lu.
