Mate Competition, Favoring Close Kin, and Village Fissioning Among the Yanomamo Indians: bibliographical excerpts


"I might add that all women get married, are married young, and married during their entire reproductive period, but not all men are successful in finding wives, and many only do so later in their reproductive life spans. (Chagnon, N.A. (1979) Mate Competition, Favoring Close Kin, and Village Fissioning Among the Yanomamo Indians. in Evolutionary Biology and Human Social Behavior. N. Chagnon & W. Irons, eds. Pp. 97)

"Paternity probability appears to be very high among the Yanomamo, based on paternity exclusion tests conducted by my medical colleagues at the Department of Human Genetics, University of Michigan Medical School. Using several different antigen systems we tested blood saples from parent/offspring triads and, allowing for possible errors due to mislabeling specimens, estimated that the nonpaternity level is about ten percent."
