An orangutan.
The answer to that question would be chimpanzee.
The bonobo (Pan paniscus) is similar to the common chimpanzee (Pan troglodytes).
a dog
There's no difference between a "chimpanzee" and a "female chimpanzee" in the way that implies they are separate species or types of animals. A female chimpanzee is simply a chimpanzee that is female. Think of it like this: Chimpanzee: This is the general term for the species Pan troglodytes. It refers to any individual of that species, regardless of their sex. Female chimpanzee: This term specifies the sex of the chimpanzee. It's a chimpanzee that happens to be female, just as a "male chimpanzee" would be a chimpanzee that happens to be male. So, when someone asks "What is the difference between female chimpanzee and chimpanzee?", it's a bit like asking "What's the difference between a dog and a female dog?" A female dog is a dog. All female chimpanzees are chimpanzees, but not all chimpanzees are female (some are male). The term "chimpanzee" encompasses both sexes.
chimpanzee
A chimpanzee is a vertebrate.
An orangutan is much more similar - as evidenced by the fact that BOTH the chimpanzee and the organutan are order: primates, suborder: haplorhini, family: hominidae while dogs are order: carnivora, suborder: caniformia, family: canidae. As you can see, while they are all mammals, the divergence between the apes and the dogs starts all the way up at the "order" level of classification. Dogs are more closely related to cats and bears than they are to primates like chimpanzees and orangutans.
Yes, they are similar.
