Final answer:
The Hominoids group includes the families Hylobatidae, Pongidae, and Hominidae, with the latter encompassing four genera: chimpanzees, gorillas, orangutans, and humans, who share a significant percentage of DNA and the ability to develop language and culture.
Step-by-step explanation:
The group Hominoids, also known as Apes, includes three families: the Hylobatidae (lesser apes), the Pongidae (orangutans), and the Hominidae (great apes and humans). The family Hominidae comprises four living genera: chimpanzees (Pan), gorillas (Gorilla), orangutans (Pongo), and humans (Homo). This family is exceptional in that all members can develop language and culture, and humans and other great apes share over 97% of their DNA.
The Hominidae family includes seven living species, characterized by substantial similarities such as the potential for language development and cultural behaviors. Notably, the genus Homo, which encompasses humans, evolved around 2.8 million years ago and is known for being bipedal with an increased brain size compared to other members of the Hominidae family.
