Book excerpt: Adoption studies have been used in humans to investigate the relative genetic and environmental influences on development. In this study, we compare rhesus macaque infants raised by adoptive mothers to those raised by their biological mothers in order to evaluate genetic and environmental effects on plasma cortisol and ACTH levels during the first 6 months of life. Blood samples were obtained from both infants and mothers once each month and assayed for cortisol and ACTH. Regression analyses showed interindividual stability across the first 6 months of life for both hormones (average r>0.30). To assess genetic and environmental effects, ACTH and cortisol levels in adopted infants (n=38) were correlated with ACTH and cortisol levels from both their unfamiliar biological mothers and their adopted mothers. Using multiple regression to control for sex differences, results showed that both cortisol (average r=0.27, p=0.05) and ACTH (average r=0.42, p=0.009) levels were correlated with levels observed in adopted mothers. Infant cortisol levels showed a trend toward being correlated with the biological mothers' cortisol (r=0.25, p
