Document Summary
Session 6: origin of the family, part 2. Survivorship: how many individuals in a species survive to different ages. Central base provisioning: model in which females and kids remain at base while males go out and get food. Permanent sexual receptivity: sexual reception that occurs any time in cycle. Neoteny: process where the traits of young individuals continue through that individual"s adulthood. Infants are born earlier to accommodate for head size, means longer dependency on parents, harder to parent. Infants and pregnant/breastfeeding females (more common) require more food. Pregnant and breastfeeding mothers require support from group, others need more energy to support her. Big brain and geographical expansion lead to evolutionary problems. Monogamy model by lovejoy to solve energy crisis. Lovejoy lists characteristics that define humans large brain bipedalism small canine teeth tool use different sexual/reproductive practices (most important) Longer living species produce offspring which require more investment from parent.
