'''Direct Fitness'' or '''Darwinian Fitness''' is a central tenant of the [[Theory of evolution]]. It is the measurement of an individual [[organisms]] ability to reproduce. Direct fitness is measured as the proportion of genes a given individual contributes to the next generation due to its direct reproductive efforts. This can be contrasted with [[inclusive fitness]] which also includes the indirect fitness measure of genes contributed to the next generation based on aid given to relatives that are not direct descendants.
