* Chimpanzees: Our closest living relatives, sharing around 98.7% of our DNA.
* Bonobos: Another close relative of humans, sharing around 98.7% of our DNA.
* Orangutans: Found in Southeast Asia, they are the most distant relative among the great apes.
* Humans: Although gorillas are not directly ancestral to humans, we share a common ancestor.
All of these species belong to the family Hominidae, which is further categorized into:
* Homininae: This subfamily includes gorillas, chimpanzees, bonobos, and humans.
* Ponginae: This subfamily includes orangutans.
So, in short, gorillas are most closely related to chimpanzees and bonobos, followed by orangutans, and lastly humans. All of them share a common ancestor and are part of the great ape family.
