A post-genomic view of behavioral development and adaptation to the environment
Peter LaFreniere and Kevin Mac Donald; 2013
Recent advances in molecular genetics are reviewed that have major implications for the biobehavioral sciences and for understanding how organisms adapt to their environments at both phylogenetic and ontogenic levels. From a post-genomics perspective, the environment is as crucial as the DNA sequence for constructing the phenotype, and as a source of information in trying to predict phenotypes. The review is organized with respect to five basic processes by which phenotypes adapt to both recurrent and novel environmental challenges, with an emphasis on the data for humans: 1) developmental plasticity, 2) epigenetic mechanisms, 3) genotypeenvironment correlations, 4) gene x environment interactions, and 5) domain-general psychological mechanisms.
