John Davies picks programmes for the academically inclined (all times pm unless stated).

Pick of the Week

Evolutionary theory versus theology - that is the (perhaps false) antithesis at the heart of Wings of Angels (Sunday 10.30 BBC2), a dramatised Horizon special. Hero of Philip Martin's thoughtful film is ornithologist David Lack (1910-73), whose study of Galapagos Islands finches confirmed Darwin's theories. Lack's belief in evolution conflicted with the Christianity of the woman he loved (Elizabeth Silva, played by Emma Fielding). Paul Rhys plays Lack, and Ian Hogg his mentor Julian Huxley.
