所有的部落成员都知道在这个地方生活一辈子、劳作一辈子对他们的适应能力有怎样的要求。
tribe 部落。
familiarity 是 familiar 这个形容词的名词形式。熟悉程度，适应程度，达尔文所说的“适应环境”。be familiar with 是习惯搭配，所以 familiarity with blablabla.就是对blablabla的适应程度。
task ，名词的释义第2项是. a difficult or tedious undertaking.困难艰巨的事情。任务。我翻译为劳作。
what was required of them by life long familiarity with the task of the area
= what of them was required by (...) familiarity (...) 他们自身的哪些东西是被“熟悉程度/适应性”所要求的，（由于“熟悉程度/适应能力”提出了要求而必须具备的）
至于为什么是那个familiarity“熟悉程度/适应能力”对原始人来说是很高要求，因为这个familiarity 是对于the task of the area，这个地儿的重重挑战向原始人提出了要求，而且这是一个一辈子的事情life long （名词作副词形容long 漫长的）+ familiarity，不断受挑战，不断适应，适应就是familiarity.
那么，原始人所了解的就是这些what is required by a familiarity.

all the members of the tribes是主语
knew是谓语
what was ......of the area是宾语
在这个宾语从句中：what 是被动式形式主语
was required 是谓语
by life long familiarity with the task of the area是谓语的实际主语。be+动词过去分词+by+主语 被动结构
