I want to know the answer to the following question:
What has evolved over time?
All the background I'm provided with is that "Meanwhile, other scripts had evolved, especially in the eastern and southern areas during the late Zhou dynasty, including regional forms, such as the gǔwén ("ancient forms") of the eastern Warring States preserved as variant forms in the Han dynasty character dictionary Shuowen Jiezi, as well as decorative forms such as bird and insect scripts.". Is that enough to answer the question?
Answer: yes
