A human is a member of the species Homo sapiens, which means 'wise man' in Latin. Carolus Linnaeus put humans in the mammalian order of primates. Humans are a species of hominid, and chimpanzees, bonobos, gorillas and orangutans are their closest living relatives.
Humans are mammals. They are also social animals. They usually live in groups. They help and protect each other. They care for their children. Humans are bipedal, which means they walk on two legs.
Humans have a complex brain, which is much larger than that of the other living apes. They use language, make ideas, and feel emotions. This brain, and the fact that arms are not needed for walking, lets humans use tools. Humans use tools far more than any other species. Their tools are very advanced.
Humans first came from Africa. There are humans living on every continent. As of 2022, there were over 7900 million people living on Earth. Overpopulation is a problem.
