When is an evolutionary approach useful?
Evidence that human behavior is or has been adaptive comes from the likelihood that it would have been useful in our environment of evolutionary adaptedness, that it forms a coherent whole with other characteristics, and that variants contribute or would be likely to contribute to reproductive success. Belsky et al. use the second and third of these, though on the third their evidence is somewhat tenuous. However, their thesis does integrate diverse facts about parenting and development. In general an evolutionary approach is useful if it integrates diverse facts, if it aids clinical practice, and if it helps us toward a full understanding of human nature.
