Horizon Season 2005 Episode 7 Who's Afraid of Designer Babies?

Who's Afraid of Designer Babies? is the seventh episode of Horizon's 2005 season. This episode explores the controversial topic of designer babies, specifically the ethical, medical, and social implications of genetically modifying human embryos.

The episode begins with a brief history of the timeline of genetic research, including the discovery of DNA and the sequencing of the human genome. The focus then shifts to the possibility of using genetic engineering to create "custom" babies with desirable traits, such as intelligence or physical appearance.

Host and narrator Dr. Kevin Fong interviews several experts in the field of genetics to get their opinions on the potential benefits and dangers of genetically modifying embryos. Proponents argue that genetic engineering could eliminate certain genetic diseases and disabilities, leading to a healthier population. However, opponents fear that such technology could lead to a society of "perfect" humans and create a new form of discrimination against those who are not genetically enhanced.

To illustrate these arguments, the episode follows the story of a couple who have a genetic disorder that causes liver failure. They are considering using in vitro fertilization (IVF) and genetic testing to ensure that their child does not inherit the disorder. However, they face opposition from those who see this as a slippery slope towards designer babies and the creation of a genetic underclass.

The episode also explores the science behind genetic engineering, including the challenges of altering DNA without introducing unintended consequences. Researchers are developing new techniques for precisely editing genes in embryos, but the technology is still in its early stages and there is much debate over its safety and efficacy.

Throughout the episode, Dr. Fong raises probing questions about the ethics of genetics and the role of science in society. He asks whether genetically engineering embryos is a moral duty to prevent suffering or a dangerous violation of nature. He also questions whether the growing trend towards genetic testing and screening will lead to a world where only those with "perfect" genes are accepted.

Ultimately, Who's Afraid of Designer Babies? raises more questions than it answers. It leaves viewers with a deeper understanding of the complex issues surrounding genetic engineering and a realization that there are no easy answers. As always with Horizon, it highlights the latest developments in a scientific field and the array of opinions around the topic. Therefore, it is a must-watch for anyone interested in the field of genetics and medical ethics.
