Two Alaskan Kodiak bears joined a small circus where the pair appeared in a nightly parade pulling a covered wagon. The two were taught to somersault, to spin, to stand on their heads, and to dance on their hind legs, paw in paw, stepping in unison. Under a spot-light the dancing bears, a male and a female, soon became favourites of the crowd. The circus went south on a West Coast tour through Canada to California and on down into Mexico, through Panama into South America, down the Andes the length of Chile to those southernmost isles of Tierra del Fuego. There a jaguar jumped a juggler, and afterwards, mortally mauled the animal trainer; and the

shocked show people disbanded in dismay and horror. In the confusion the bears went their own way. Without a master, they wandered off by themselves into the wilderness on those densely wooded, wildly windy, subantarctic islands. Utterly away from people, on an out-of-the-way uninhabited island, and in a climate they found ideal, the bears mated, thrived, multiplied, and after a number of generations populated the entire island. Indeed, after some years, descendants of the two moved out onto half a dozen adjacent islands; and seventy years later, when scientists finally found and enthusiastically studied the bears, it was discovered that all of them, to a bear, were performing splendid circus tricks.

On nights when the sky is bright and the moon is full, they gather to dance. They gather the cubs and the juveniles in a circle around them. They gather out of the wind at the center of a sparkling, circular crater left by a meteorite which had fallen in a bed of chalk. Its glassy walls are chalk white, its flat floor is covered with white gravel, and it is well-drained, and dry. No vegetation grows within. When the moon rises above it, the light reflecting off the walls fills the crater with a pool of moonlight, so that it is twice as bright on the crater floor as anywhere else in that vicinity. Scientists speculate that originally the full moon had reminded the two bears of the circus spotlight, and for that reason they danced. Yet, it might be asked, what music do the descendants dance to? Paw in paw, stepping in unison what music can they possibly hear inside their heads as they dance under the full moon and the Aurora Australis, as they dance in brilliant silence?

The two Alaskan Kodiak bears were part of a nightly parade, pulling a covered wagon. They were also trained to perform various tricks, including somersaults, spinning, standing on their heads and dancing on their hind legs in unison.

The circus travelled south from Alaska along the West Coast, passing through Canada, California. Mexico and Panama. They continued into South America down the Andes, through Chile and ultimately reached the islands of Tierra del Fuego.

A jaguar attacked a juggler and fatally mauled the animal trainer. This tragedy caused shock and dismay among the circus members, leading to the disbanding of the show.

After the circus disbanded the bears wandered into wilderness and settled on uninhabited islands!

After leaving the circus, the bears settled on the densely wooded, windy islands of Tierra del Fuego.

The bears found the island's climate ideal. They mated, multiplied and over generations populated the island. Eventually, their descendants expanded to nearby island, creating a thriving population.

Scientists found that the bears, despite being isolated for decades, retained their ability to perform circus tricks. Every bear on the island exhibited these skills, indicating a strong generational memory of their past.

A circular meteorite crater with white chalk walls and a gravel floor became the bears' gathering place for dancing.

Scientists think the bears began dancing under the full moon because the moonlight may have reminded them of the circus spotlight.

On bright, moonlit nights, the bears gather to dance. They arrange themselves in a circle with clubs and juveniles in the center, stepping in unison as if reliving their circus days under a spotlight.

The crater's reflective properties amplify the moonlight, creating a luminous environment that mirrors the conditions of a spotlight. This setting likely reinforces the bears' instinct to perform their inherited dance routines.

The crater with its smooth, glassy walls and dry, vegetation-free floor, suggests it was formed by a meteorite impact in a chalk bed. Its unique features make it a striking natural amphitheater.

The full moon and the Aurora Australis accompany the bears' dances.

While scientists understand the visual cues that inspire the bears to dance, the mystery remains about the "music" they might perceive. Whether it is an imagined rhythm, an inherited memory or a product of their natural surroundings is still unknown.
