Tim Lewens on Lamarckian inheritance in cultural evolution

[This is a second post originating from reading Tim Lewens book Cultural Evolution. The first, on the application of the concept of population thinking to culture, is here.]

One of the most repeated criticism of the analogy between cultural and biological evolution is that inheritance in the former, but not in the latter, is Lamarckian. Things may be, to a certain extent, complicated (“Lamarckian” evolution might mean different things; the concept of soft inheritance, which might include “Lamarckian” forms, is no more a taboo in biology), but the nuts and bolts – which are, I think, what really matters for the analogy cultural/biological evolution – are not.

I am reading Tim Lewens’ new book Cultural Evolution (I am still halfway through it, so perhaps other posts will follow). One aspect I found interesting – and I imagine this will not come as a surprise to readers of this blog – is a peculiar conception of what identifies an approach to culture as “evolutionary”.

Lewens attacks the problem from a familiar perspective (see, for example, here), defining a taxonomy of possible evolutionary commitments for cultural explanations. As usual, some of them are too broad (Lewens calls them “historical” approaches), while others are too restrictive (he is skeptical of replication-based accounts of cultural evolution): things are more interesting in the middle.
