Thousands more are added to the list every year. Modern classification is part of the broader science of taxonomy, the study of the relationships of organisms, which includes collection, preservation, and study of specimens, and analysis of data provided by various areas of biological research. A considerable number of classification changes as well as insights in recent years have been the result of comparisons of nucleic acid (genetic material) sequences of organisms. widely accepted by the early 19th century and is still the basic framework for all taxonomy in the biological sciences today.
