Chimpanzee Research: An Examination Of Its Contribution To Biomedical Knowledge And Efficacy In Combating Human Diseases, Jarrod Bailey, Jonathan Balcombe, Theodora Capaldo

Jonathan Balcombe, PhD

Research on captive chimpanzees incurs considerable animal welfare, ethical and financial costs. Advocates of such research claim these costs are outweighed by substantial advancements in biomedical knowledge, and that the genetic similarity of chimpanzees to humans enables the former to make critical contributions to preventing, diagnosing and combating human diseases. To assess these claims, we examined the disciplines investigated in 749 studies of captive chimpanzees published from 1995-2004 inclusive, and subjected 95 randomly selected papers to a detailed citation analysis:

49.5% (47/95) of papers had not been cited at the time of this study; 38.5% (34/95) were cited by 116 …

Self-Harm In Laboratory-Housed Primates: Where Is The Evidence That The Animal Welfare Act Amendment Has Worked?, Jonathan Balcombe, Hope Ferdowsian, Debra Durham

Jonathan Balcombe, PhD

The 1985 amendment to the United States Animal Welfare Act (AWA) to promote psychological well being of primates in the laboratory represents an acknowledgment of an important welfare problem concerning nonhuman animals. How effective has this amendment been? Perhaps the best-known contributor to psychological distress in primates in the laboratory is nonsocial housing; yet, available analyses suggest that little progress has been made in avoiding single-caging of these animals. Another way to assess psychological well being is to examine rates of self-abusive behavior in laboratory primates. If the AWA has been effective, then post-AWA self-harm rates might be lower than …
