This 2015 Oxford study of 38 humans and 25 macaques drew correlations of brain activities between the two species. The study title included buzzwords such as “reward” and “decision making” and the study focused on the ever-popular “frontal cortex.”

Humans and macaques are separated by 25 million years of evolutionary adaptations and developments. Studies done with macaque subjects don’t automatically have human applicability.

Was a major reason for the study’s comparisons to provide justifications for keeping macaques as study subjects? Accepting these justifications and going along with the popular memes would ease the way for whatever cruelties researchers want to inflict on our primate relatives.
