 As we saw in the previous section, the original genic selectionists had particular problems with their treatment of the interactor. While they admitted that the “vehicle” was necessary for the selection process, they did not want to accord it any weight in the units of selection debate because it was not the beneficiary, but rather an agent of the beneficiary. Soon, however, there emerged a new angle available to genic selectionists (Waters  1986).[16]
