I want to know the answer to the following question:
What are some fields of knowledge concerning the animal world that have been revolutionizes in the 21st century?
All the background I'm provided with is that "Animal communication, and indeed the understanding of the animal world in general, is a rapidly growing field, and even in the 21st century so far, a great share of prior understanding related to diverse fields such as personal symbolic name use, animal emotions, animal culture and learning, and even sexual conduct, long thought to be well understood, has been revolutionized.". Is that enough to answer the question?
Answer: yes
