Just in case you have ever wondered whether chimpanzees like cheese: the answer, if Bow is any indication, is a resounding "Yes!" Today, for lunch, Bow was presented with the following foods: an apple, two bananas, cherry tomatoes and sugar snap peas and a plate of cheddar cheese. He chose to have the cheese first. He was quite eager to try the cheese.
Now, we don't have cheese every day. But Bow has had cheese in the past, and he recognized this as cheese and called it by name.
