Despite the recommendations of the scientific advisory board, the NIH still chooses to remain ignorant regarding the psychological "complexities" of sentient persons being held captive for research.
Clearly, "species-typical behavior" for chimpanzees does not include living in captivity. No "complexity" or "enrichment opportunities" can ever replace living in the wild. And "colony characteristics" cannot be replaced by forced cohabitation and psychological trauma. These are not subtle nuances or minor differences -- especially for the 50 remaining government "owned" chimpanzees.
"The NIH decision on chimpanzees in research is a step forward," said Dr. Lori Marino, NhRP's Science Director. "But the fact that they have rejected the recommendation to increase living space for chimpanzees reflects the fact that chimpanzee legal rights still need to be recognized so that their welfare is a priority and not at the whims of others."
