How do data (see below) from studies of infanticide among primates support or falsify each of the following four hypotheses: (1) the “cannibalism” hypothesis, (2) the “social pathology” (Dolhinow) hypothesis, (3) the “resource competition” hypothesis, and (4) the “reproductive competition” or “sexual selection” (Hrdy) hypothesis. Hints: Follow the essay organization format outlined in the paper writing handout: (a) explain/introduce research question, (b) Explain each hypothesis, (c) Explain what each hypothesis predicts, (d) Explain how the data (see below) fit or do not fit predictions from each hypothesis, (e) present conclusions. Test several hypotheses using the excel database 3
Field observations (data):
1) Infanticide usually occurs after male “takeovers.”
2) Males kill unrelated infants.
3) Infanticide was first observed by Monot and Hrdy among Langurs that lived next to human settlements.
4) Infanticide was later observed in “undisturbed” environments.
5) Infanticide is observed most frequently in species with uni-male harems and male-transfer social organization (e.g., Gorillas, Langurs, Patas, Red Howler).
6) Infant mortality (cause undetermined) is much higher after male takeovers in Red Howlers.
7) Females sometimes exhibit “sham estrus.”
8) Females become sexually receptive sooner if their infants are killed.
9) Infanticide probably reduces the rate of population growth.
10) Over some of the geographic range of Langurs, infanticide has not been observed.
11) Female Chimpanzees sometimes kill and eat unrelated infants.
12) Male Chimpanzees sometimes kill infants of strange females.
13) Human children are more frequently abused when they are co-residing with a step-parent than children who are co-residing with both genetic parents or a single genetic parent or grandparents.
