Each was defined in some detail, in some cases sufficient to enable modern biologists to create mathematical models of the described. Aristotle's method, too, resembled the style of science used by modern biologists when exploring a new area, with systematic data collection, discovery of patterns, and inference of possible causal explanations from these. He did not perform experiments in the modern sense, but made observations of living animals and carried out dissections. He names some 500 species of bird, mammal, and fish; and he distinguishes dozens of insects and other invertebrates. He describes the internal anatomy of over a hundred animals, and dissected around 35 of these. Aristotle's writings on biology, the first in the, are scattered across several books, forming about a quarter of his writings that have survived.

The main biology texts were the,,,,, and, as well as the lost drawings of The Anatomies which accompanied the History. Apart from his pupil,, who wrote a matching, no research of comparable scope was carried out in, though medicine in Egypt continued Aristotle's inquiry into the mechanisms of the human body. Aristotle's biology was influential in the Islamic world. Translation of Arabic versions and commentaries into Latin brought knowledge of Aristotle back into Europe, but the only biological work widely taught in medieval universities was On the Soul. The association of his work with medieval, as well as errors in his theories, caused scientists such as and to reject Aristotle. Criticism of his errors and secondhand reports continued for centuries.

He has found better acceptance among, and some of his long-derided observations in have been found in modern times to be true. Aristotle spent many years at in Athens. Aristotle's background [ ] (384–322 BC) studied at in Athens, remaining there for about 20 years. Like, he sought in his, but unlike Plato he backed up his views with detailed and systematic observation, notably of the of the island of, where he spent about two years, and the in the seas around it, especially of the Pyrrha lagoon in the island's centre. This study made him the earliest scientist whose written work survives. No similarly detailed work on was attempted until the sixteenth century; accordingly Aristotle remained highly influential for some two thousand years.
