Why was the method of classification of animals proposed by Aristotle not accepted?

Answer:
Aristotle classified animals on the basis of their habitat, i.e., whether they live on land or in water. But these animals, otherwise are very different from each other in many respects and such a classification does not prove much helpful. So, the method of classification by Aristotle was not accepted.
