Q & A
What was the key development that allowed Homo sapiens to stand out from other hominins?
-The key development that allowed Homo sapiens to stand out from other hominins was the mastery of fire, which provided warmth, light, protection, and enabled cooking, leading to more efficient digestion and energy allocation to brain functions.
What is the 'cognitive revolution' that is believed to have occurred around 70,000 years ago?
-The cognitive revolution refers to the development of the capacity for large-scale collaboration through the ability to communicate complex information, which allowed Homo sapiens to discuss collective fictions like deities and spirits, enabling even strangers to cooperate effectively.
Why did humans decide to start cultivating plants and breeding animals?
-The decision to start cultivating plants and breeding animals was likely driven by environmental pressures such as severe droughts and lack of food, which led to the transition from nomadic hunter-gatherers to settled farmers.
How did the development of written text impact human civilization?
-The development of written text marked the transition from prehistory to history, allowing for the recording of culture, customs, traditions, and laws. It also enabled the preservation of knowledge and the ability to communicate across vast distances and time.
What are some of the major achievements of human civilization since the ancient times?
