An evolutionary documentary
By the end of Barbet Schroeder's brief 1978 documentary on Koko, a female gorilla being taught sign language and other aspects of human communication on the campus of Stanford University from her birth in 1971 to this very day, I had fallen in love with the noble beast. Filmed in secret as to avoid legal troubles with the San Francisco Zoo (which technically owned Koko at the time of filming), Schroeder's chronicle asks many tough questions, such as if a gorilla being raised in a humanistic environment has any significant rights, or if raising a creature in such a way is ethical.
