Continuous controversies about how Aristotle's teleological biology relates to modern biological science address some widely debated questions in contemporary philosophy of science. Three main groups of objections made by contemporary science against Aristotle's biology can be identified: 1) Aristotle's biological teleology is too anthropomorphic; 2) the idea is tied too substance based; 3) Aristotle's final ends contradict the mechanistic spirit of modern science, which is looking for physical causes. There are two ways of dealing with these objections. The first consists in showing misinterpretations of Aristotle's thought that underlie these arguments. A second line of defense explores the idea that teleological concepts are not only incorporated and widely used in contemporary science, but that in fact biology does not have to renounce teleology in order to reconcile with the modern scientific mind. I suggests that a complete understanding of complex biological phenomena can only be achieved by combining different approaches to this issue.
