- Washoe had an adoptive son, Loulis
- Researchers only signed 7 words to him
- Loulis acquired his vocabularly of over 50 signs from other chimpanzees he lived with
- (Washoe, Moja, Tatu + Dar)
- mirroring the manner in which human children learn language.
SUPPORTS G+G
This supports G&G, as it shows the chimps must have learnt and understood the signs, to be able to teach Loulis.
Furthermore, it shows how chimps can acquire language, as Loulis evidently learnt 50 signs.
