The statement "New developmental mechanisms, rather than modifications of existing mechanisms, account for morphological evolution." is not entirely accurate. While new developmental mechanisms can certainly contribute to morphological evolution, modifications of existing mechanisms can also play a significant role. Therefore, the principle should be modified to state that both new developmental mechanisms and modifications of existing mechanisms can account for morphological evolution.
