 There exists a longstanding debate among both scientists and philosophers over exactly what natural selection can explain, one begun by Sober and Neander who were concerned with what natural selection can explain (Sober 1984, 1995; Neander 1988, 1995). In a recent expansive treatment, Razeto-Barry &amp; Frick 2011 distinguish between the creative and non-creative views of natural selection. On the non-creative view, natural selection merely eliminates traits while doing nothing to create new ones; the latter phenomenon is the result of mutation. Proponents of the creative view see natural selection as a creative force that makes probable combinations of mutations that are necessary for the development of at least some traits. While Razeto-Barry and Frick grant that natural selection cannot explain the origin of traits that arise by a single mutation, they argue that it can explain the occurrence of sequences of phenotypic changes that would otherwise be wildly unlikely to occur without selection operating to cause the spread of the changes prior to the final one in the sequence. Additionally, it is disputed whether natural selection can explain why an arbitrary individual has the traits it has (Walsh 1998; Pust 2004; Birch 2012). On the positive view, selection affects the identity of individual organisms, and it is part of the identity of an individual to have been produced by the parents that produced it, so natural selection explains why individuals have the traits they do. On the negative view, the explanatory scope of natural selection is limited to population level properties. Razeto-Barry and Frick further consider the question of whether natural selection can explain the existence of individuals, ultimately arguing against it.
