What aspect of human biology can be better understood through animal models?

Animal models play a critical role in biomedical research because they closely mimic the complex biological processes found in humans. By studying these models, researchers are able to investigate the underlying mechanisms of diseases, test potential treatments, and understand the progression of various health conditions in a controlled environment. For instance, examining how a specific disease affects an animal model can provide insights into similar processes in humans, allowing scientists to observe interactions at the cellular and molecular levels, the efficacy of drug responses, and the overall impact on physiology.

This approach is vital for understanding multifaceted biological systems that involve interactions among various genes, proteins, and environmental factors. Such information can lead to significant advancements in treatment methodologies and therapeutic strategies, which would be more challenging to study directly in humans due to ethical, logistical, and practical constraints. Thus, the use of animal models is indispensable for gaining knowledge about complex biological and disease processes that are relevant to human health.
