Aristotle's classification system was mainly focused on plants and animals, the two kingdoms that were most visible and familiar to him. He based his classification on observable physical characteristics and traits, and at the time, these were the most prominent groups of organisms that were recognizable and distinguished easily.
Protozoa and Animalia are the two groups in the domain system that are most similar in physical characteristics. Both groups consist of organisms that are multicellular, eukaryotic, and exhibit a wide range of morphological diversity. Additionally, they both have complex cellular structures and exhibit various modes of reproduction.
