The project Nim movie was about a chip that was being teached to learn American sign languge. The book half brother was about a chimp too. The chimp was being taught american sign languge too. Other things that are the same about them are they bit people, had toys, had a family, they were taken away from their family, had clothing, and had dipers. They were both in desks too.
Stuff that were diferent about them were that Nim smoked and drinked alchohal while Zan did not do that. Zan did not bite a lot while Nim bit a lot. Zan did not hump things but Nim humped his doll, a rock, and a cat. Nim was not to nice but Zan was really nice and respected his family.
