Question

Find out how the gradual adaptation from primitive man to modem man must have taken place.

Answer 1

1. Walking Upright (Bipedalism): Primitive ancestors like Australopithecus (4–2 million years ago) were among the first to walk on two legs. See predators from a distance. Use their hands for carrying tools and food.
2. Larger Brain Size: Over time, human ancestors like Homo habilis and Homo erectus developed larger brains. 
3. Use of Tools: Early humans like Homo habilis made simple stone tools for cutting and hunting. 
4. Discovery of Fire: Homo erectus was the first to use fire about 1.5 million years ago. Cook food, making it easier to digest. Stay warm in cold climates.
5. Development of Language: Primitive humans began communicating using simple sounds and gestures. Over time, Homo sapiens developed languages to share ideas, plan hunts, and build communities.
6. Building Shelters: Early humans lived in caves for protection. Later, they built shelters using wood, animal skins, and stones, adapting to different climates.
7. Agriculture and Settlements: Around 10,000 years ago, humans began farming instead of hunting and gathering. Settle in one place. Domesticate animals. Form villages and civilizations.
8. Precise use of the hand: The human thumb can be opposite the other fingers (Opposable Thumb), which allows him to grasp objects and perform very fine tasks.
9. The structure of the mouth and jaw changed: Early humans ate raw meat, so their teeth were large and strong. The introduction of cooking food caused the jaw to become smaller and the brain to grow in size.
10. Culture and civilization developed: Relationships, religion, art, and education developed, allowing humans to create advanced societies.
11. Development of technology and science: Humans changed the world even faster by developing technologies such as medicine, transportation, computers, and the Internet.
