Off Dominica in the Caribbean, scientists studying nearly 4,000 sperm whale codas found the animals combine click patterns in ways strikingly similar to human speech. Their “vowel-like” sounds shift in tone and timing, creating rich structures that may carry meaning — a major step toward understanding one of Earth’s most social species.
