Study Notes
- Early humans, or hominids, first evolved in Africa around an unknown date, with much of the fossil record yet to be discovered.
- The Paleolithic period (2.6 million to 11,700 years ago) marks the beginning of human existence and includes several waves of migration out of Africa.
- Hominid species like Homo habilis, Homo erectus, and Homo neanderthalensis were mostly nomadic hunter-gatherers in Africa, Europe, and Asia.
- Early hominids adapted and used stones as tools around 2.6 million years ago for tasks such as hunting, butchery, and food preparation.
- Around 800,000 years ago, early hominids discovered fire for cooking, providing more nutrients and improving overall success.
- The Neolithic era (10,000-12,000 years ago) marked the start of human civilization with the development of agriculture in ancient Mesopotamia.
- Farming allowed humans to settle in one place, establishing communities, and led to the growth of societies.
- Humans adapted to their environments by clearing forests, building structures, and developing systems of irrigation, enabling the success of agriculture.
- Early hominids underwent biological adaptations, such as increased brain size, during a period of rapid climate change around 800,000 to 200,000 years ago.
- Larger brains suggested greater ability for complex thought and more effective problem-solving in a changing environment.
