请问这英语的结构是什么?

请问这英语的结构是什么?TPO阅读里面的一句话：This 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.我不太明白后面半句：more evidence that predator pressure favors the evolution of begging calls that are hard to detect and pinpoint.more evidence是主语吗?那谓语是什么...ms 5楼的答案比较有说服力，但是如果data跟evidence是同位语的话，是不是应该逗号变and啊，另外有没有人可以帮忙翻译一下这句话啊。
