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, gorillas and orangutans are their closest living relatives.
Humans are mammals. They are also social animals, and usually live in groups. They help and protect each other. They care for their children for many years until they can do so for themselves. Humans are bipedal, which means they walk on two legs.
Humans have complex brains, which is much larger than that of 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 can range from simple sticks as weapons, to very advanced projectile weapons, such as guns.
Humans first evolved in Africa. They soon spread out across the world, and began living on every continent. As of 2023, there were over 8.1 billion living on Earth.
