PREFACE
Thisbookisacollectionofsomeofmyscientificpapers,alongwithaccounts
of how they were written and short postscripts that attempt to bring the
readerup-to-date.Ihavenaturallyconcentratedonmyearlypapers,thefive
between 1971 and 1976 that had such a strong influence. In addition to
these I have included an empirical paper on lizard size and reproductive
success. I have also included a paper (with Jon Seger) showing a bias in
female choice toward the interests of daughters, a widely neglected paper
that I hope this volume will help resurrect. My thinking on self-deception
is scattered in various places, including chapter 16 of my book Social Evo-
lution. Here I reproduce a paper with Huey Newton analyzing the contri-
butionofself-deceptiontothecrashofanairplane,alongwithapaperjust
publishedthatsummarizesmycurrentunderstandingofthesubject.Since

Description:Robert Trivers is a pioneering figure in the field of sociobiology. For Natural Selection and Social Theory, he has selected eleven of his most influential papers, including several classic papers from the early 1970s on the evolution of reciprocal altruism, parent-offspring conflicts, and asymmetry
