Both proponents and critics of behavioral genetics, reproductive cloning, and genetic testing have mistaken beliefs about the role of genes in human life. Taking Biology Seriously calls attention to the social context in which both the science and our ethical precepts and public policies play a role.

Each year, roughly a million new cases of cancer appear in the US, and more than 500,000 Americans die annually of premature death. Although medical progress has slowed cancer mortality, its incidence is increasing roughly six times faster than cancer mortality is decreasing. Breast cancer, in particular, has been increasing about one percent each year since 1973. At least two of the factors responsible for this surge in breast cancer are women's use of medically-prescribed synthetic hormones and the exposure of the entire population to chemicals such as dioxin. Both exposures increase the...

Reprogenetic technologies, which combine the power of reproductive techniques with the tools of genetic science and technology, promise prospective parents a remarkable degree of control to pick and choose the likely characteristics of their offspring. Not only can they select embryos with or without particular genetically-related diseases and disabilities but also choose embryos with non-disease related traits such as sex.
Prominent authors such as Agar, Buchanan, DeGrazia, Green, Harris, Robertson, Savulescu, and Silver have flocked to the banner of reprogenetics. For them, increased...
