Scientists like to categorize things, especially in the field of biology, because it helps them understand and organize the tremendous diversity of life on Earth.
Step-by-step explanation:
Scientists like to categorize things, especially in the field of biology, because it helps them understand and organize the tremendous diversity of life on Earth. Classification is an important step in understanding the present diversity and past evolutionary history of life. By grouping organisms into categories based on their characteristics, scientists can make sense of the overwhelming diversity of living things. Classification also allows scientists to communicate and generalize their findings to better understand and conserve different species.
