根据以下内容回答题：
“There is no arguing about taste”一runs the Latin proverb．But taste did not just hap—pen．Cuhural，historical，biological and environmental events have interacted to cause frogs，for example，to be viewed as delicious in southem China but to be regarded with revulsion（厌恶）in northern China．Even though much remains unknown，tastes cannot be dismissed as in．arguable or illogical；an attempt will be made here to discover why，as Lucretius put it，“What is food to one man may be fierce poison to others?”Among the approximately thirty million tribal people of India，a total of 250 animal species are avoided by one group or another．Most of these people will not eat meat from a tiger or any of various snakes．Although they say they feel a relationship with these animals，it is obvious that both are highly dangerous and that hunting them systematically would be foolish． Monkeys are avoided，probably because they look like human beings in appearance；in these tribes，man-eating is viewed as extremely cruel．A reluctance to eat some female animals has been attributed to respect for the mother"s role，but it could also be due to a policy of allo-wing the females to reproduce and provide more young for people．Many tribes avoid eating any animal that has died of unknown causes all intelligent attitude in view of the possibility that the animal might have died from a disease that could spread to humans．Animals that consume gar-bage are similarly avoided，an adaptive step that prevents contact with parasites（寄生虫），and that might explain why members of one tribe eat any of twenty-one different species of rats，but not the house rats．
