Are species real categories or just conventions? Are species natural kinds? Are teleological statements a distinctive feature of biology? Can life sciences escape from teleology? These are common issues in philosophy of biology. This paper aims to show that in order to answer to each of these questions it is inevitable to take a position respecting the others. Therefore, there is a historical relation between the concept of species and teleological issues. In order to analyse such relation, I will take (...) a historical perspective.After making such historical reconstruction focused on the Aristotle, Linnaeus, Buffon and Lamarck thoughts, I will analyse the Darwinian peculiar view respect teleology and his ideas about species. Although Darwin set out the collapse of teleological essentialisms in biology, there are important vestiges of teleology in his theory. (shrink)

Current Perspectives in Philosophy of Biology.

Abstract Drawing upon evolutionary theory and the work of Daniel Dennett and Nicholas Agar, I offer an argument for broadening discussion of the ethics of disenhancement beyond animal welfare concerns to a consideration of animal “biopreferences”. Short of rendering animals completely unconscious or decerebrate, it is reasonable to suggest that disenhanced animals will continue to have some preferences. To the extent that these preferences can be understood as what Agar refers to as “plausible naturalizations” for familiar moral concepts like beliefs (...) and desires, then they can make moral claims on us and provide support for intuitive opposition to disenhancement.
