The Arabian Oryx, whose distinctive horns are widely believed to have given rise to the unicorn legend, is back from the brink of extinction in the deserts of the Arabian peninsula. About 1,000 of the wild Arabian or White Oryx now exist owing to nearly three decades of successful breeding, the Swiss-based International Union for Conservation of Nature said Thursday. The environmental group said efforts to breed captive oryx and release them back into the Arabian Peninsula, the only place this species is found, began in Oman in 1982, a decade after the last one was apparently shot in the wild.
