A pronoun problem

a pronoun problem

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

Craig Venter, whose company had competed with a public consortium in the race to sequence the genome, said at a press conference that the smaller-than-expected gene count shows that “we simply do not have enough genes for this idea of biological determinism to be right. The wonderful diversity of the human species is not hard-wired in our genetic code. Our environments are critical.” In the United Kingdom, The Guardian headlined its story, “Revealed: The Secret of Human Behaviour. Environment, Not Genes, Key to Our Acts.”

In this passage I’m not so sure about what the underlined ‘it’ stands for.

‘It’ seems to represent ‘The Guardian’ at first, but at a second glance it seems to be able to refer to the contend of the preceding sentence.

Regards.
