Animal farm. Part 3, Arrival of the clones.

This documentary imagines what a farm inhabited only by creatures made by science would look like. Professor Randy Lewis has added the gene for making spider silk to a goat so that now from the goat's milk a protein can be extracted which can then be spun into spider silk. We also see how a jellyfish gene has been added to pigs to make them glow in the dark - this flourescing gene has also been extracted from coral and added to fish which are already being sold as pets. Meanwhile, John P. Philips has created 'enviro-pigs' which produce phosphorous-free manure and we meet Scamper, a world-famous racing horse now in retirement, whose owner Charmayne James has had cloned. Oliver A. Ryder shows us around a laboratory which contains frozen genes from 600 species which are endangered. Professor Steve Brown introduces work being done in an underground laboratory, home to thousands of mice who are being experimented on to manipulate genes for a vast range of conditions including alcohol preference, obesity, homosexuality and even infidelity. The consequences of manipulating genes in such a way are not really discussed here in any detail which is a failing of the programme. Nevertheless the range and advancement of science shown is startling.
