Suomi uses Freud’s idea
What happens early affects adulthood
However, research is cloudy
Research with animals has permitted a more direct study of the relationship

Unusually supportive moms
Unusually supportive moms
2% of macaque mothers exhibit very supportive care of their infants
Crossbreeding
Crossbreeding
Process of breeding with the intention to create offspring that share the traits of both parent
lineages
