indeed, it is elsewhere by Pinker and other evolutionary theorists
What is the meaning of "indeed, it is elsewhere by Pinker and other evolutionary theorists"? Does it mean "as Pinker and other evolutionary theorists state somewhere else"?
Context:
Steven Pinker writes:
"... that toolbox, however, can be used to assemble Sunday afternoon projects of dubious adaptive value."
It could be argued – indeed, it is elsewhere by Pinker and other evolutionary theorists – that that adaptive value may be not ‘dubious’ but explicit.
