Before that, scientists had wondered whether dolphins took a long time to learn sound and echolocation or whether they were hard-wired at birth.

The calf was born June 11 to a deaf Atlantic bottlenose dolphin at the Marine Mammal Conservancy. It died Friday.

The calf’s sounds were recorded in an isolated environment without multiple dolphins present.
