> Research on Apes became immoral over time

Teaching apes sign language became viewed as immoral?

[ReaLNero]

Raising them only by interacting with a single person (not of their species!) would be immoral for a human baby, and depending on your views of ethics, also immoral for a gorilla.

Oh, I didn't realize that was somehow required to teach them sign language.
