Zoology researchers have for a long time labored on trying to somewhat understand the language of animals. Dolphins, as mammals, have been thought to possess high intelligence, and people have tried to understand their speaking and singing in the oceans.
I wanted to propose in expending a greater effort and energy in trying to understand the language of a wider variety of animals. It seems that animals and their languages have a lot to teach us. Although we do not understand what noises they make, it still might be possible to understand more about their languages and what they are trying to communicate.
These types of studies would have lots of benefits, including giving us a better perspective about our own thinking and language capabilities, and how it fits in with the rest of the animal kingdom.
