Read their Darwin?

Does " read their Darwin" mean "understand Darwin's theory of evolution"?

Context:

The 'mistake' or 'by-product' idea, which I am espousing, works
like this. Natural selection, in ancestral times when we lived in
small and stable bands like baboons, programmed into our brains
altruistic urges, alongside sexual urges, hunger urges, xenophobic
urges and so on. An intelligent couple can read their Darwin and
know that the ultimate reason for their sexual urges is procreation.
They know that the woman cannot conceive because she is on the
pill. Yet they find that their sexual desire is in no way diminished
by the knowledge. Sexual desire is sexual desire and its force, in an
individual's psychology, is independent of the ultimate Darwinian
pressure that drove it. It is a strong urge which exists independently
of its ultimate rationale.
