Great Ape Analysis: Europe vs North America

[Haliaeetus]

I am curious about this. They showed as such for some time at Zootierliste but disappeared.

It is a pity that institutions keeping chimpanzees are behind in terms of forming self-sustaining, breeding, genetically pure groups. This was done for orangutans decades ago, and for Asian elephants in the last decade (despite both forming strong social bonds, being prone to fight with unfamiliar ones, insert the full list of problems cited by chimpanzee people).

In Europe the zoos tend to separate the subspecies and to phase out the hybrids. It's one of the causes of the relative decline of chimps in Europe.
