In this work, three international authorities on behaviour genetics and their collaborators present the most recent findings from the landmark Colorado Adoption Project. This first large-scale, longitudinal adoption study, launched in 1975, tracked the children, biological and adoptive parents, and home environments of 245 adoptive families and 245 matched non-adoptive families. Its design facilitated analyses of genetic and environmental influences on development of unparalleled scope and diversity - via both parent-offspring and sibling comparisons, and longitudinal and multivariate assessments. Following two introductory chapters, the authors focus successively on general and specific cognitive abilities, school achievement, language disorders, personality, stress, body size and obesity, motoric development, sex differences, competence and family relationships. Before summarizing and concluding, they then turn to issues like the meaning of "shared" environment, the correlations and interactions between "nature" and "nurture" and the practical implications of the findings for adoption policy.
