The development and progress of human medicine not only benefit from the hard work of scientists, but also the silent sacrifice made by experimental animals. Before drug development enters the clinic, a large number of animal experiments need to be done to explore the drug's efficacy, toxicity, and safe dose, However, there are many differences between humans and animals such as rats, pigs, dogs, rabbits, etc. Even if the physiological structure of the animal and the law of drug reaction are correctly understood, the recognition results cannot be easily and blindly transferred to humans. Which of the following, if true, best supports this view?
