Systematic zoology, also known as experimental zoology, refers to the scientific study of the diversity of animal life. It involves the classification, identification, and naming of various animal species based on their morphological, physiological, ecological, and molecular characteristics. Other synonyms for systematic zoology include animal taxonomy, animal classification, and animal systematics. These terms are often used interchangeably to describe the same field of study. Systematic zoology is critical in understanding the evolutionary history and relationships between different animal species. Scientists utilize various tools and methods, such as DNA sequencing and comparative anatomy, to analyze the relationships between animal groups and create accurate taxonomic classifications.
