Early humans wore hides of animals, barks of trees, and leaves as clothing. These materials provided protection from harsh weather conditions and the environment. As humans evolved and developed better tools, they learned to process animal hides more effectively and create more sophisticated garments. The use of these natural materials shows how early humans adapted to their surroundings and used available resources to meet their basic needs for survival and protection.

Early humans lived in caves. Caves provided natural shelter and protection from wild animals, harsh weather, and extreme temperatures. They offered a safe refuge where early humans could rest, store food, and gather as a group. Archaeological evidence from cave sites shows that early humans used caves as dwelling places for thousands of years before they began to build their own structures and eventually settled in permanent settlements with the advent of agriculture.

Oxen were used for ploughing. These strong animals were domesticated and trained to pull ploughs through the soil, making agricultural work more efficient and productive. The use of oxen for ploughing was a significant development in human civilization as it allowed farmers to cultivate larger areas of land and increase crop production, which supported the growth of settled communities and civilizations.

Humans settled in one place when people began to practice agriculture. The development of farming and the cultivation of crops made life more organized and predictable. Instead of constantly moving in search of food, people could stay in one location, grow their own food, and build permanent settlements. This shift from a nomadic hunter-gatherer lifestyle to a settled agricultural lifestyle marked a major turning point in human history, leading to the development of villages, towns, and eventually complex civilizations.

Humans moved from place to place primarily because they kept on moving in search of food. As hunter-gatherers, early humans depended on hunting wild animals and gathering wild plants for survival. When food sources in one area became depleted or scarce, they had to migrate to new locations where they could find adequate food supplies. This nomadic lifestyle continued until humans discovered agriculture and began to settle in permanent communities.

Ancient humans employed several methods of hunting to obtain food. Collective hunting was a common practice where people hunted as a group, which allowed them to tackle larger and more dangerous animals. They also dug pits and used them to trap animals, making the hunting process more efficient and less risky. These organized hunting techniques required cooperation, planning, and communication among group members, demonstrating the social and intellectual development of early humans.

Axes were made for multiple practical purposes in early human societies. They were used to cut trees and remove barks, which provided materials for shelter and tools. Axes were also used to dig pits for trapping animals during hunts and to remove the skin of animals after hunting. The versatility of the axe made it one of the most important tools in early human life, serving both survival and construction needs.

Archaeology is the study of pre-historic humans and their way of life through material remains. Excavated material remains such as tools, pottery, bones, and artifacts are the main sources for archaeological studies. By carefully examining and analyzing these physical remains found in archaeological sites, archaeologists can reconstruct how early humans lived, what they ate, what tools they used, and how their societies were organized. Archaeology provides crucial evidence about human evolution and the development of early civilizations.

Anthropology is the study of humans and their evolutionary history. It examines how humans developed over time, how different human populations adapted to various environments, and how human societies and cultures evolved. Anthropology combines knowledge from biology, archaeology, and social sciences to understand the complete story of human development from our earliest ancestors to modern times.

Early humans used stones and bones as weapons for hunting. Stones were shaped and sharpened to create tools and weapons for cutting and striking prey. Bones and horns of animals were also fashioned into weapons such as spears, arrows, and hunting tools. These simple weapons were essential for early humans to hunt animals for food and protect themselves from predators.

Flint is the best stone for making weapons. Flint is a hard, sharp-edged stone that can be easily chipped and shaped to create cutting and piercing tools. Early humans preferred flint because it could be worked into sharp points and edges, making it ideal for hunting weapons and cutting tools used in daily life.

The wheel was the first major scientific invention of humans. It was a revolutionary invention that transformed human civilization and made transportation, agriculture, and various other activities much more efficient. The wheel enabled the movement of goods and people over distances, and it became fundamental to the development of carts, chariots, and later machinery.

The pictures found in rock paintings depict hunting scenes and dancing pictures. These paintings show early humans engaged in hunting animals, which was their main occupation for survival. The dancing pictures suggest that early humans also had social and cultural activities, indicating that they gathered together for celebrations and rituals.

The main occupation of early humans was hunting and gathering. Cave paintings tell us valuable information about the past, including the lifestyle, activities, and culture of early humans. These paintings reveal what animals they hunted, how they hunted, their social gatherings, and their artistic abilities. Rock paintings serve as important historical records that help us understand how early humans lived, what they ate, and how they organized their societies.

Early humans lived in caves. Caves provided natural shelter and protection from wild animals and harsh weather conditions. The cave walls were also used by early humans to create rock paintings and engravings, which served both artistic and possibly ritualistic purposes. Living in caves was practical for early humans as these natural formations offered safety and were often located near water sources and hunting grounds.

Early humans domesticated dogs and oxen. Dogs were among the first animals to be domesticated and helped humans in hunting by tracking and chasing prey. Oxen were domesticated for their strength and were used to pull carts and help in agricultural work. The domestication of these animals marked an important step in human civilization as it provided companionship, assistance in hunting, and labor for farming.
