The types discovered by comparative anatomy and developmental history must therefore agree.

Thus, developmental modularity improves evolvability and allows for the emergence of complex anatomies from genomes which need not be as complex. A study by Yang provides empirical evidence for the hypothesis that modularity confers evolvability.
