검증된 단계별 안내1
Understand the timeline of Earth's geological periods. Geological periods are divisions of Earth's history based on significant events in the planet's development, such as mass extinctions or the emergence of new life forms.
Recall that anatomically modern humans (Homo sapiens) are relatively recent in Earth's history. They did not exist during ancient periods like the Cambrian, Devonian, or Jurassic, which are associated with much earlier forms of life such as trilobites, fish, and dinosaurs, respectively.
Focus on the Pleistocene epoch, which is part of the Quaternary period. This epoch is characterized by repeated glaciations and the evolution of Homo sapiens. It spans from approximately 2.6 million years ago to about 11,700 years ago.
Understand that Homo sapiens first appeared during the later stages of the Pleistocene epoch. This period is significant for the development of human culture, tools, and migration patterns.
Conclude that the correct geological period for the appearance of anatomically modern humans is the Pleistocene, as it aligns with the evolutionary timeline of Homo sapiens.
