100币,找牛人做英语答疑
his prediction was supported by data collected in one survey of 24 species from an Arizona forest,more evidence that predator pressure favors the evolution of begging calls that are hard to detect and pinpoint.逗号后面的pressure怎么翻?

predator pressure是捕食压力.也就是说同种动物数量越大,因为食物恒定,他们之间的竞争压力会逐渐增大,反而会影响种群数量.
翻译为：
在对亚利桑那森林24种物种进行调查并分析数据之后,证明了他的假设：由于捕食压力,动物求食的动作或者声音越发的进化得难以监测和定位.
再问： more evidence that predator pressure favors the evolution of begging calls that are hard to detect and pinpoint. 这一部分的句子结构能不能帮我分析下？看不懂。谢谢
再答：首先是这部分和data....from an Arizona forest是并列的。 that后面的从句修饰more evidence，也就是说后面是说一个什么样的"more evidence"。that后面的话可以单独提出来分析 predator pressure .. begging calls ==> 是第一部分 that ... detect and pinpoint 为第二部分第二部分中第一个that同上面一样，也是修饰名词的，这部分是形容begging calls are hard to detect and pinpoint。也就是说原句可以分拆成以下单独句子： his prediction was supported by data collected in one survey of 24 species from an Arizona forest. his prediction was supported by more evidence. predator pressure favors the evolution of begging calls. begging calls are hard to detect and pinpoint.
