Homo sapiens is a modern human species that originated in Africa and appeared about 200,000 years ago. During this time, humanity has undergone many biological, cultural and social changes.Biologically, Homo sapiens is larger in size and body shape than other human species such as Homo neanderthalensis and Homo erectus. They also have better logical, creative and linguistic thinking. These changes helped Homo sapiens to adapt to new habitats and grow rapidly.Culturally, Homo sapiens developed many new technologies such as stone tools, fire, and pottery. They also built the first villages and cities. These changes made it possible for Homo sapiens to live more centrally and cooperate with each other more effectively.Socially, Homo sapiens developed more complex relationships with each other. They formed small groups, tribes and even nations. These changes made it possible for Homo sapiens to protect themselves and their offspring from threats from the environment and other animals.About 100,000 years ago, Homo sapiens began to migrate out of Africa and onto other continents. They replaced other human species such as Homo neanderthalensis and Homo erectus and became the only human species on Earth.The migration of Homo sapiens has had a major impact on the environment and other animals. They have hunted many animals to extinction and destroyed many natural habitats. However, they also contributed to the development of new civilizations and made it possible for humans to live in many places on Earth.Homo sapiens is a species with strong adaptability and development. They have undergone many changes during the last 200,000 years and are currently the only human species on Earth.These changes have enabled Homo sapiens to survive and thrive, and will continue to help them face future challenges. Thanks to that Homo sapiens developed rapidly and became the only human species on Earth.
