Homo is a genus that includes modern humans, known scientifically as Homo sapiens, as well as several extinct species. Members of this genus are characterized by their ability to walk upright on two legs, use complex tools, and communicate through language. They have larger brains compared to other primates, which allows for advanced problem-solving and social interaction. The Homo genus emerged around 2.5 million years ago, with early species like Homo habilis and Homo erectus. Over time, these species evolved, leading to the development of modern humans. Today, Homo sapiens are the only surviving species of the Homo genus, showcasing remarkable adaptability and cultural diversity.
