 More recent attention to reductionism in situ within different life science contexts has led many philosophers to revisit the perennial aspects of reductionism, many of which were simply tangential to controversies over theory reduction. A number of current debates are actually unconscious returns to neglected issues, albeit in different ways and in different contexts. That developmental biology has returned to the center of discussions is not surprising because of its enduring status as a biological topic inviting reflection on reductionist themes. The same can be said for ecology and functional anatomy, although they are at present more peripheral for many philosophers. Socially and politically tinged aspects of reductionist research in biology, such as racial categorizations based on genetic profiles, also continue to provoke philosophical analyses (see  Section 5).
