The past several decades have seen tremendous advances in the field of medical genetics.
Currently, the application of genetic testing on human embryos determines if embryos harbor a lethal
condition or a serious genetic disease. The purpose of this sort of testing is not to “improve” the offspring
of a couple. Rather, current testing strategies focus on helping couples to have a healthy family
in an efficient manner. Newly emerging technologies have opened the door to test embryos for an exponentially growing
number of traits. Additionally, recent reports describe the actual modification of human embryonic DNA. The implications
from the application of this technology are many and have the potential to fundamentally change the social paradigm
of the human experience. Embryonic testing and modification does have the potential to accomplish good and is not inherently
amoral. However, thoughtful consideration should be given by scientists, legislators, and the general population
on how to apply this technology in a manner that is both appropriate and equitable and does not result in further social
stratification and polarization, both within individual nations and the global community.
