Progression of Animals
From Wikipedia, the free encyclopedia
On the Gait of Animals (or "De Incessu Animalium", or "On the Progression of Animals") is a text by Aristotle on the details of gait and movement in various species of animals.
Aristotle's approach to the subject is to ask "why some animals are footless, others bipeds, others quadrupeds, others polypods, and why all have an even number of feet, if they have feet at all; why in fine the points on which progression depends are even in number."
It's a good example of the way he brought teleological presumptions to empirical studies.
