Final answer:
Scientists in the field of systematics organize and classify organisms based on evolutionary relationships. They contribute to building and maintaining the "tree of life" by updating and refining the classification of organisms.
Step-by-step explanation:
In the field of systematics, scientists accomplish the organization and classification of organisms based on evolutionary relationships. They use data from various sources, such as fossils, body part structures, molecules, and DNA analysis. By combining this data, scientists can construct phylogenetic trees to represent the evolutionary history of organisms.
Scientists in systematics contribute to building and maintaining the "tree of life" by updating and refining the classification of organisms as new information and discoveries are made.
