But their genetic code suggests that the results of their research will be more easily transposable to the human species… The research focuses on the functioning of the nervous system and hormones, particularly in relation to digestion, and is causing these little primates sometimes severe suffering.

All were subsequently euthanized or decapitated, their bodies autopsied, sampled and sent for post-mortem analysis.

One Voice wrote to the President of the MNHN, the Director of the Essonne DDPP and the French Minister for Higher Education, Research and Innovation, to find out exactly what was happening to the grey mouse lemurs on the benches of the National Museum of Natural History’s Brunoy annex. We learned that the facility where the grey mouse lemurs are kept has been breaking the law for years, and we’re still waiting for proof of its regularization.
