一个英语句子求解析

It turns out that we're fighting one of the most evolutionarily-conserved learning processes currently known in science, one that's conserved back to the most basic nervous systems known to man.
麻烦讲解以下两点，如果有什么需要额外注意的就更好了，谢谢！
1、句子中涉及的语法（比如 ，one 这是什么语法？turns out that 呢？）
2、句子整体的结构是怎样的？

Answer 1

as单独引导定语从句
　　as单独引导定语从句时，先行词可以是一个词，也可以是一个句子或短语。例如：
　　(1)
She
is
late,
as
is
often
the
case.她迟到了，这是经常的事。(先行词是整个主句)
　　(2)
To
shut
your
eyes
to
facts,
as
many
of
you
do,
is
foolish.对事实视而不见--你们好多人都是如此的愚蠢。(先行词是不定式短语)

Answer 2

as
many
people
think正如很多人想的那样
as在这意思是像。。。一样，正如。。。
其实不应该这么翻译
因为前面已经直接用了not
正如很多人想的一样，蜘蛛不是昆虫，甚至跟昆虫一点关系都没有

Answer 3

one of...，one that‘s
...的其中之一，后面的one指代前者。
it turns out that
结果是…，证明是…;
例句:
1.
It turns out that this widespread outage is a perennial event.
事实证明，这种大面积的宕机是多年来持续发生的情况。
这句话是It turns out that引导的，之后的主语是We，后面one引导的从句修饰的是
one of the most evolutionarily-conserved learning processes
