Hamburg's famous zoo, the Tierpark Hagenbeck, was founded in 1907 by Carl Hagenbeck as the first zoo with moated, barless enclosures. |
The regulars were left barless but, like the White Russians of Paris and the Cubans of Miami, they religiously awaited the day they could return. |
This plan takes advantage of the fact that barless is the most recessive of a series of alleles. |
