In evolutionary biology, inclusive fitness is one of two metrics of evolutionary success as defined by W. D.

Absolute fitness is standardised relative fitness.

WebDec 23, 2013 · Inclusive fitness is, of course, the solution to Darwin's difficulty over social insects: altruistic (sterile) individuals are thought to enjoy a net positive inclusive fitness, with indirect fitness gain outweighing their direct fitness loss.
