On Animals

"On Animals" is a philosophical text by Aristotle that explores the nature, structure, and behaviors of animals. It examines how different animals are adapted to their environments, their senses, and how they move and reproduce. Aristotle classifies animals by their characteristics, such as blood or bloodless, and discusses their instincts and function in nature. The work combines observation with logical analysis to understand the biological diversity and purpose of animals, laying important groundwork for zoology and biological sciences. It remains influential for its systematic approach to studying the natural world.
