Possum model is an important research tool, widely used in many fields such as biomedicine, ecology and behavior. Such models not only help scientists understand the complexity of biological systems, but also reveal a wide range of pathogenesis and environmental responses.

Possums, as small, adaptable marsupials, have unique physiological characteristics, such as their immune system and reproductive style, making them an important role in scientific research. Possums' immune systems are of particular interest because they are able to fight off a wide range of infections, including viruses and bacteria. This characteristic makes possums an ideal model for studying infectious diseases, especially natural defense mechanisms against various pathogens.

In genetic research, possums are favored for their relatively simple genomic structure. Scientists use possum genome data to explore the relationship between genes and traits, especially in terms of individual growth and development, behavior, and adaptive traits. Through genetic modification technology, researchers can create specific disease models, which can help gain insight into the pathogenesis of human diseases, as well as search for potential treatments.

In addition, the possum model is also of great value in ecological research. Their habitat and reproductive behavior provide a wealth of data for the study of ecosystems, especially when it comes to observing the effects of climate change and human activities on habitats. By observing how possums react under different environmental conditions, researchers are able to gain insights into ecological adaptation and species survival strategies.

The possum model also presents a unique advantage in behavioral research. Because possums exhibit certain social behaviors and adaptive abilities, scientists can use these behavioral observations to explore the evolution of the animal's social structure, selection behavior, and survival skills.
