Psychologist Marcus provides an accessible discussion of genetic history and current research. Along the way, he disabuses readers of some common misconceptions about genes and alters the groundwork of the nature versus nurture debate. Marcus accomplishes these goals by reaching down to the molecular level of DNA, giving a crystal-clear explanation of how its information is manifested through cascades of protein activation and regulation. Marcus impresses upon readers the fact that there is only a tiny genomic difference between humans and primates, but an immense one between their minds. Marcus also convinces his audience that there isn't one gene "for" some attribute, such as intelligence, which is implied when the human genome is compared to a blueprint. Instead, Marcus asserts, genes act in "exquisite harmony." A lucid, pleasing chronicle of how genes construct the human mind."
