Here is Darwinian theory's disjunction problem: the process Darwin discovered can't tell the difference between these two genes or their traits until cross-over breaks the linkage between one gene, that is going to increase its frequency, and the other one, that is going to decrease its frequency. If they are never separated, it will remain blind to their differences forever. What is worse, and more likely, one gene sequence can code for a favorable trait—a protein required for survival, while a part of the same sequence can code for a maladaptive trait, some gene product that reduces fitness. Natural selection will have an even harder time discriminating these two traits. Since evolution cannot solve the disjunction problem, the right conclusion for the materialist is to accept eliminativism by denying that neural states have as their informational content specific, particular, determinate statements which attribute non-disjunctive properties and relations to non-disjunctive subjects.
