A pronoun problem

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

That does sound pretty deterministic. But what the man wrote was, “They created us, body and mind,” which is very different. Lewontin has used the doctored quotation in five different places.

Is there any charitable explanation of these “gross errors,” as Trivers called them? One possibility may be Dawkins's and Wilson's use of the expression “a gene for X” in discussing the evolution of social behavior like altruism, monogamy, and aggression.

I'd like to ask a question regarding the underlined 'them'.
I cannot figure out what it refers to.
(I don't have even slightest idea about it.)

Regards.
