Problems with pronouns and other references

problems with pronouns and other references

The passage below is from ‘the Blank Slate’ by Steven Pinker.

http://evolbiol.ru/blankslate/blankslate.htm

The human genome, then, is fully capable of building a complex brain, in spite of the bizarre proclamations of how wonderful ?it is [that people are almost as simple as worms]. Of course “the wonderful diversity of the human species is not hard-wired in our genetic code,” but we didn't need to count genes to figure ?that out — we already know ?it from the fact that a child growing up in Japan speaks Japanese but the same child growing up in England would speak English. ?It is an example of ?a syndrome we will meet elsewhere in this book: scientific findings spin-doctored beyond recognition to make a moral point that could have been made more easily on other grounds.

In this passage I want to check out what the underlined references refer to.
I have my answers as follows:

?it : 'that people are almost as simple as worms'
?that : 'the wonderful diversity of the human species is not hard-wired in our genetic code'
?it : 'same with ?'
?It : 'same with ?'
?a syndrome : 'scientific findings spin-doctored beyond recognition to make a moral point that could have been made more easily on other grounds'

Can you check these out for me?

Regards.
