Under the high-energy conditions of the decomposition of this extraterrestrial crystal cluster, it is essential to channel the energy; otherwise, if the body cannot disperse the energy, it will start to mutate automatically. This is what happened when the researcher initially experimented with mice. Under such massive energy overflow, the body can easily evolve in unpredictable directions, potentially resulting in some failed evolutions.
The reason the megalodon could evolve in the correct direction is its massive body size, which is sufficient to digest this energy. However, this also means that its evolutionary cycle is very long, requiring millions of years to achieve a very low degree of evolution. Although the human body is not small, it's not large either. Thus, after absorbing excessive energy, it is easy to become irritable and unbearable. If more energy is absorbed further, it might also end up like the mouse experiment.
