Knut (born at the Zoologischer Garten Berlin on 5 December 2006) is a captive-born polar bear that is currently the subject of international popularity and controversy. He was rejected by his mother at birth and is consequently being raised by zoo handlers.
After the unproblematic gestation time of the 20-year old polar bear Tosca, Knut and his brother were born on 5 December 2006. He was the first polar bear birth at the Berlin Zoo in over thirty years. Tosca, who is a former circus performer, rejected Knut and his brother. After four days, the brother died and Knut was separated from his mother by zoo workers. He spent the first 44 days of his life in an incubator.
On 23 March 2007, Knut was presented to the public for the first time.
The German Environment Minister, Sigmar Gabriel officially adopted Knut. The polar bear is now seen as a symbol for the endangered species. Knut will be the mascot animal for a conference on endangered species in 2008 held in Bonn.
