A natural history by David Attenborough
A series of 13 programmes 7: Victors of the Dry Land
Reptiles were the first backboned creatures to solve the problems of becoming fully committed terrestrial animals. Two innovations were vital. The scaly waterproof skin conserved body moisture and the sealed egg protected the baby reptile inside its own ' private puddle '. These developments once enabled the mighty reptiles to rule the world -as the dinosaurs did-and today enable them to survive even on roasting hot lava fields and in burning deserts.
But reptiles are far from being inefficient relics of a bygone age. Their behaviour is amazingly complex -and the snakes include some of the most efficient and deadly hunters in the world.

This week:
Your Life in Their Files
How much do the authorities know about you? And even more important, how accurate are their files, and how can you check? Is an increasing erosion of our traditional attitudes toward privacy the price we must now pay for law, order, or even national security? Over the last few years the police have gained the capacity to file on computer, facts, suspicions, even seeming irrelevancies that concern your life, your career, your future. Do they, as they say, confine their records simply to those matters that are essential to efficient policing? Or are there more doubtful - even sinister - implications?
Jenny Conway and Nick Ross investigate.
Producer PAUL HAMANN Editor TIM SLESSOR
