RACHEL MARTIN, HOST:
Good morning. I'm Rachel Martin. When archaeologists found a large seashell in a French cave in 1931, they thought it was a ceremonial cup. But after 90 years and fresh research, scientists now say it's a musical instrument crafted about 18,000 years ago. The tip of the conch shell has been expertly broken off and holes punched out to produce different notes. To demonstrate, they hired - who else? - a French horn player.
