翻译求助(OG上的)

1Until recently,scientists did not know of close vertebrate analogue to the extreme form of altruism observered in eusocial insects like ants and bees,whereby individuals cooperate,sometimes even sacrificing their own oppotunities to survive and reproduce,for the good of others.

蓝色的部分用法对吗,know不是动词吗,后面为什么直接跟着of?是不是一种省略,到底省略了哪个单词呢?

2The passage suggest that Jarvis's work has called in to question which of the following explanatory variables for    naked mole rate behavior.

question在这里是"质疑"的意思吗?

看的有些糊涂,请高手们给小女子指点下迷津吧,谢谢哦!

1，存在know of/about结构啊，知道，了解，懂得，do you know of a good bookshop?

2，call in to question是质疑的意思

MW字典的解释：

call in question

or
            call into question
            : to cast doubt upon <a report calling into question the drug's effectiveness>
