Homininae is a group of animals that includes humans and our close evolutionary relatives, like chimpanzees and gorillas. It's kind of like a family where everyone is related to each other in some way.
Our family, the Hominidae, is part of a larger group called the Homininae. This group includes two tribes, the Hominini and the Gorillini. The Hominini tribe includes us, humans, and our extinct relatives, like Homo erectus and Neanderthals. The Gorillini tribe includes gorillas and some extinct relatives.
We can tell that all these animals are related because they have similar physical features, like long arms, big brains, and a similar bone structure. Scientists study homininae to learn about our ancestors and how we evolved over time.
