Birds do it, bees do it, monkeys in the trees do it. And television cannot get enough of it. It is wild about sex, and though in Hong Kong it cannot show too much of it explicitly when in its human form, it can throw off its inhibitions when it comes to animals. While humans grapple with the morality of what goes on in bed, it all happens in the animal kingdom in Wild And Weird (World, 9pm): orgies, necrophilia, homosexual acts, sex changes and sex-induced violence in nature provide ample footage for this episode, Wild Sex. The New Zealand-made documentary begins with the rhetorical question of whether sex is worth all the bother, it is resulting in so much global aggression. Large and small creatures on Earth, from elephants to antlered beetles, are shown to risk all for lust. The whiptail lizard provides the answer. Several million years ago a mutant female must have managed to clone itself without needing a male, resulting in a population of identical lizards. But a world of identical women is proven not to be a satisfactory solution in the struggle for survival. All the whiptails are vulnerable to the same threats, from disease, parasites and climate change, and as a result their days are numbered as a species. Variety, after all, is the spice fundamental to sustainable life, achievable only through the process of sex. Few of us, though, need this programme to teach us that. Conflict in the human world continues regardless. In 60 Minutes (World, 10pm), Bob Simon reports on the battle brewing between Jews and Jews in Israel, with an increasingly fraught division arising between orthodox and non-orthodox adherents. One day the orthodox Jews may wake up to find they have more in common with zealous Muslims than the non-conformists. 60 Minutes has now been running for 32 years. Its regular correspondents are all veterans, who have been with the show a minimum of nine years. Mike Wallace joined at the beginning, in 1968; Morley Safer in 1970; Ed Bradley in 1981; Steve Kroft in 1989 and Lesley Stahl in 1991. Andy Rooney began his regular on-air segment, A Few Minutes With Andy Rooney, in 1978. In what CBS describes as a unique agreement, the show also borrows CNN's Christiane Amanpour for some international reports. Co-operation in the cut-throat American television market is rare indeed. While the show continues to rank in the top 10 in American ratings and pull in the awards, we are unlikely to see many other fresh faces. Beyond the American market, 60 Minutes is of mixed relevance. It is, of course, targeted primarily at American viewers and their concerns, which are usually domestic. Once again, the fraught battle over a woman's right to decide whether to terminate a pregnancy crops up tonight, with anti-abortionists fighting for their constitutional right to publish the names and pictures of doctors who perform abortions, a practice which pro-choice advocates says puts these doctors' lives at risk. The rest of the world looks on in bemusement.
