IQBAL Mallik, 35, is in the process of sketching the profile of homo sapiens who get a kick out of teasing animals at the Delhi Zoo. Most of them, Iqbal says, are males in groups. Monkeys and chimpanzees are mimicked, tigers are provoked, carnivorous otters are fed popcorn, and stones find their way into hippo gullets. In the face of such assault, monkeys start shaking uncontrollably, the chimps (which incidentally share 94 per cent of their DNA with humans) become hyperactive and the tigers get restless.
