Which of the following is not one of the principles of evolutionary developmental biology (evo-devo)?
A) Animal groups share similar molecular mechanisms for morphogenesis.
B) Changes in the timing of gene expression are important in the evolution of new structures.
C) Evolution of development is not responsive to the environment.
D) Changes in the locations of gene expression in the embryo can lead to new structures.
E) Evolution occurs by modification of existing developmental genes and pathways.

The principle that the evolution of development is not responsive to the environment is not one of the principles of evo-devo. In fact, environmental factors play a key role in shaping developmental processes and can lead to adaptations in response to changes in the environment. The other principles listed, such as the role of molecular mechanisms and gene expression changes in evolution, are all key tenets of evo-devo.
