Incidentally, it’s unfortunate that preliminary work on this can’t be done on chimpanzees anymore. Without delving into all the complexities of great-ape research ethics, I think research would generally be OK if the harm/risk is minimal and I could see volunteering myself as a test subject under similar circumstances to the chimpanzee (e.g., being young and having no significant medical conditions). Both of those are true here.
