英语语法好的进来，帮我看一个托福句子

流星小语UID: 3249036

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.

请问这句话的后半句more evidence that predator pressure favors the evolution of begging calls that are hard to detect and pinpoint.
中第一个that引导的是定语从句还是同位语从句，从句部分从哪到哪？

目前我看这后半句话像病句，如果把后半句的第一个that改成about或concerning就可以解释通了，但我这个想法可能不对，所以请大家帮忙

谢谢

第一个that是evidence的同位语从句，这个句子一直到pinpoint结束。第二个that是修饰calls的定语从句。
然后我觉得这个more evidence是data的同位语
