ABSTRACT
Biosocial science is particularly relevant to research on human family systems and parenting behavior because the family is the universal social institution within which the care of children has been based and where cultural traditions, beliefs, and values have been transmitted to the young as the individuals fulfill their biological potential for reproduction, growth, and development. The genetic inheritance of each individual sets a range for defining the potential expression of biological and behavioral attributes. In response to national concern, in 1978 Congress passed the Adolescent Health Services and Pregnancy Prevention and Care Act. There was particular concern about the trend toward increasing numbers of adolescents 16 years and younger who become pregnant, carry the pregnancy to term and choose to rear their infants. The cross-cultural and historical records indicate that, although parenthood by young adolescent girls was relatively rare, when it did occur it was in a very different social context.
