Homo (disambiguation) facts for kids
Homo is a scientific group, or genus, that includes modern humans (Homo sapiens) and many of our close ancient relatives. Think of a genus as a family name for different types of living things that are very similar.

The Homo Genus
The word Homo comes from Latin and means "man" or "human being." In biology, a genus is a way to group together different species that share many common features and are believed to have come from a common ancestor. The Homo genus is very important because it tells the story of human evolution.
Our Species: Homo sapiens
The species name for modern humans is Homo sapiens. The word sapiens means "wise" in Latin. So, Homo sapiens means "wise human." We are the only species from the Homo genus that is still alive today. All people living on Earth now belong to the Homo sapiens species.
Ancient Human Relatives
Over millions of years, many different species of humans lived on Earth. These ancient humans were also part of the Homo genus. They were our relatives, but they were not exactly like us. They had different features and lived in different ways. Some of the most well-known ancient human species include:
- Homo habilis : This species lived about 2.4 to 1.4 million years ago. Their name means "handy man" because they were known for making and using simple stone tools.
- Homo erectus : Living from about 1.9 million to 110,000 years ago, Homo erectus means "upright man." They were the first human species to walk fully upright and were also the first to leave Africa and spread to other parts of the world, like Asia. They also learned to control fire.
- Homo neanderthalensis (Neanderthals): Neanderthals lived in Europe and parts of Asia from about 400,000 to 40,000 years ago. They were very strong and adapted to cold climates. They made complex tools, wore clothing, and even buried their dead. Modern humans and Neanderthals lived at the same time for a while.
How We Study Ancient Humans
Scientists called paleoanthropologists study ancient humans. They look for fossils, which are the preserved remains of bones, teeth, and other parts of ancient creatures. They also look for artifacts, which are objects made or used by ancient humans, like stone tools or cave paintings. By studying these clues, scientists can learn about how our ancient relatives lived, what they ate, and how they changed over time.
Other Meanings of "Homo"
While Homo is mostly known for referring to humans, the word can also appear in other ways:
- Greek Prefix ὅμο- : In Greek, the prefix ὅμο- (homo-) means "the same." You might see it in words like "homogeneous," which means something that is the same throughout.
- Homogenized Milk: Sometimes, people use "homo" as a short way to say "homogenized milk." This is milk that has been processed so that the fat particles are evenly mixed throughout, preventing the cream from separating and rising to the top.
