"Parental Investment and Sexual Selection" (1972) is a paper by Robert Trivers on parental investment.
Incipit:
- "Charles Darwin's (1871) treatment of the topic of sexual selection was sometimes confused because he lacked a general framework within which to relate the variables he perceived to be important: sex-linked inheritance, sex ratio at conception, differential mortality, parental care, and the form of the breeding system (monogamy, polygyny, polyandry, or promiscuity)."
