Scientists use a system of taxonomy to help understand the relationships between organisms. Taxonomy is the science of classifying living things into groups based on their shared characteristics. The basic unit of classification is the species, which is a group of organisms that can interbreed and produce fertile offspring. Species are then grouped into genera, families, orders, classes, phyla, and kingdoms. This hierarchical system of classification allows scientists to organize and understand the diversity of life on Earth.
