This episode of Darwin's Dangerous Idea can be viewed online via the BBC iPlayer until April7 2009.
In the three-part series, Darwin’s Dangerous Idea, broadcast on BBC2 to mark the 200th anniversary of the birth of Charles Darwin and the 150th anniversary of the publication of On the Origin of Species, broadcaster Andrew Marr explores the impact of the theory of evolution by natural selection on science, politics and society.
While the first and third episodes, respectively entitled Body and Soul and Life and Death, explore the historical spread of Darwin’s theory and the way it can be employed within conservation and ecology, the second episode, Born Equal?, includes a short section (between 00:45:12 and 00:56:20) that could be used in bioethics teaching.

The Killer in Me illustrates just how far genetic testing for disease has developed. Testing for conditions caused by mutation in a single gene has been possible for some while, and examples have been considered previously in relation to programmes in the Bitter Inheritance series, e.g. Huntington’s disease (Episode 5) and Gorlin Syndrome (Episode 4). In The Killer in Me, four celebrities agree to undergo pioneering genetic tests for conditions that are under the influence of several different genes and environmental factors, such as diet. It is promised that the battery of tests will indicate their potential risk, i.e. their predisposition, to several common diseases, including heart disease, cancer and Alzheimer’s. The tests are supervised by Paul Jenkins, a Senior Clinical Researcher at Queen Mary’s School of Medicine and the co-founder of the company ‘Genetic Health’. As he explains, “We know the environmental influences that can predispose to disease, now we are able for the first time to start to determine your genetic predisposition to those diseases” (00:01:39).
The decisions about which tests to take, and the celebrities’ responses to the results of those tests, offer insights into the ethical dilemmas posed by screening. GMTV presenter Fiona Philips re-examines her mother’s past medical history, which included both breast cancer and Alzheimer’s which unfortunately led to her death. She reflects on the terrible ordeal her mother suffered for eight years, and wonders what actions she would take if the test presented that she was at high risk of Alzheimer’s (00:02:49-00:05:17 and 00:17:50-00:19:10*).

“Isn’t it about time we put the whole country’s DNA on the database once and for all?” This is the central question posed in Give us your DNA, an episode of the BBC documentary Panorama. Since its creation in 1995, the Police National DNA Database (NDNAD) has provided the police with an exceptionally powerful tool to detect and prevent crime in the UK. However in both its creation and implementation the database has generated numerous contentious ethical issues such as infringement of civil liberties. With the assistance of personal accounts and expert commentary, this programme examined whether there is a strong argument in favour of putting every UK citizen onto NDNAD.
