Document Summary
Originated 200 million years ago= mother-child relationship (olygokyphus) Some organisms have more of an impact on children. Peer contact and individual differences can alleviate these issues: gene-environment interaction. Rhesus monkeys are polymorphic for the serotonin transporter gene. Monkeys with the short allele are more vulnerable to maternal deprivation. When placed in proximity to other monkeys that are younger than them can reduce this effect. Hyper-aggressiveness is always more present if the child was not raised by the mother: attachment. Is adaptive, not learned, tied to fear, emerges in infancy and shows lifelong continuities. In hunter gatherers the mother-child relationship is very close (resembles old-world primates: affectional systems.
