Biological classification, or scientific classification in biology, is a method of scientific taxonomy used to group and categorize organisms into groups such as genus or species. These groups are known as taxa.
The three-domain system is a way for classifying biological organisms.

Over the years, scientists have developed several systems for the classification of organisms.
