much in the same manner that a "bee dance" can be universally understood across hives/colonies except it's based on actual sounds rather than movements.
This actually makes them less like humans. Almost all social animals have instinctive ways to communicate. Think of it as hard-coded stuff which does not need to be learned. A bee is born knowing to communicate using dancing.
What makes humans different is that we don't have universally shared words for anything. Neither objects, nor squares, nor colors.
Very large language families like Indo-European can share many root words. But no word is universally shared or instinctively understood. All must be learned.
