A chimpanzee, named Sarah, gave us clues
how creatures think and what they think about.
This immigrant from Africa brought news
that placed our human specialness in doubt.
A series of experiments were done
on what was going on in Sarah’s mind,
a personality who could be won
to learn the signs for fruits on which she dined.
The keepers toiled to keep this subject caged
and mute until some M&Ms were cast
by which her real reactions might be gauged.
Could she, aunt-like, forgive us at the last?
She said "Hello" when it was time to go.
She was our kin in ways we hardly know.
