Explanation:

Carl Linnaeus developed a classification system for organisms primarily based on their physical characteristics (morphology), such as the structure and appearance of organisms. The concepts of evolutionary history and genetics - based classification came later with the development of evolutionary theory and modern genetics, which were not part of Linnaeus's classification approach. So he used physical characteristics to classify organisms.
