Yes, but any particular measure of success or fitness is arbitrary. Individual survival, rate of reproduction, number of descendant in generation 3, or in generation 4, or generation 5... Evolutionary biologists have to pick a measure to use in empirical work based on the requirements of their particular research question and the exigencies of the moment.
