The ring-shaped coral islands known as atolls, like this one in the Maldives Islands in the Indian Ocean, may trace their formation to sea levels repeatedly rising and falling over hundreds of thousands of years, geologists say.

Why Some Geologists Say Charles Darwin's Theory of Coral Atoll Formation Is Wrong

Sea levels rising and falling over hundreds of thousands of years may have helped build the oceanic structures

The study begins with fossilized kauri trees (pictured) that died over 41,000 years ago.
