“Darwin offered the proof of his own pets that dogs can comprehend words and sentences, and pointed out that many birds, besides parrots, have the power of articulation”
Birds and dogs can talk to each other? Then who is smarter, human who only can communicate with human and animals that can communicate to each other, even though they have different species. Can other animals understand each others like dog and bird?
A dog: Hello little bird
A bird: Hi big dog 😀
Tiger: Be prepare! I’m going to eat you.
Deer: Help! Help!
Are they communicate like this? But we just can’t understand them.
