Final answer:
Biosystematics aims at the classification of organisms based on their evolutionary history and establishing their phylogeny using parameters from all fields of studies.
Step-by-step explanation:
Biosystematics, also known as systematics, is the field of organizing and classifying organisms based on their evolutionary relationships. Scientists use combined data from various sources such as morphology, cytology, and genetic analysis to construct phylogenetic trees that represent the evolutionary history and relationships among species. This process helps in delimiting various taxa of organisms and establishing their relationships. The aim of biosystematics is to classify organisms based on their evolutionary history and establish their phylogeny using parameters from all fields of studies.
