In evolutionary biology, inclusive fitness is one of two metrics of evolutionary success as defined by W. D. Hamilton in 1964: • Personal fitness is the number of offspring that an individual begets (regardless of who rescues/rears/supports them) • Inclusive fitness is the number of offspring equivalents that an individual rears, rescues or otherwise … WebMar 2, 2024 · Inclusive fitness encompasses both direct and indirect fitness.
