This paper analyzes modularity in biological and cultural evolution. Evolutionarily modularized or quasi-independent biological traits can vary relatively independently from other traits and have higher variability, and developmentally modularized biological traits have robust developmental processes and higher variability and heritability. First, I point out that these two concepts should not be confused. Second, by focusing on the concept of evolutionary modularity, I argue that it can increase (and actually have increased at least in some cases) evolvability also in the context of cultural evolution if cultures are modularized through looking at some specific examples of cultural evolution.
