"Although whale song is nothing like human language, I wouldn’t be surprised if some marine mammals have the ability to communicate in a complex way.
Are you the same person who claimed they didn't have syntax at all or someone different? Why claim that when they don't have syntax, and then move goalposts to bits of information?
https://www.uw360.asia/the-difference-between-human-and-cetacean-brains/ Are you aware cetaceans have more lobes in their brain than humans ?
This extra lobe of tissue has something to do with processing emotions, but also something to do with thinking that we humans just don’t have.
This unique evolution of the cetacean’s entire limbic system, which is a combination of multiple structures in the brain that deal with emotions and the formation of memories, suggests that cetaceans have the ability to process more complex thoughts and emotions than humans. Since the system is so large in cetaceans, and the unique paralimbic lobe merges with the cortex, it is believed that the lobe may create a mixture of both emotional and cognitive thinking.
Humans are always comparing animals TO OURSELVES and when they fall short we consider ourselves better, but we don't do the comparison the other way and subtract points from ourselves when we fail against animals.
I think this is my overall point and why our estimation of ourselves and other life on earth is so flawed.
