Model organisms are species that are extensively studied in biological research to provide insights into broader biological principles applicable to other organisms, including humans. They are selected for their ease of maintenance, genetic tractability, short life cycles, and relevance to biological processes under investigation. The importance of model organisms lies in their ability to act as experimental systems where fundamental biological questions can be addressed under controlled conditions. By studying these organisms, scientists can uncover mechanisms of genetics, development, physiology, and evolution, which are often conserved across species. Model organisms have been instrumental in discoveries ranging from the genetic code to developmental pathways and disease mechanisms. The use of model organisms is important because they allow for reproducibility
