What the Early Humans and Beginning of Civilisation Class 9 NCERT Book PDF Covers
Most of human history happened before writing was invented. The Class 9 Social Science NCERT Book Chapter 4 Early Humans and Beginning of Civilisation traces this long story, from how our ancestors evolved in Africa to the first cities on river plains. It explains how tools, farming and trade slowly changed the way people lived.
- Before writing: how archaeology, tools and fossils help us study the time before written records.
- Evolution: human ancestors from Homo habilis to Homo sapiens, and the spread out of Africa.
- Stone Age: the Palaeolithic, Mesolithic and Neolithic stages, with cave art at Bhimbetka.
- Neolithic Revolution: the shift to farming, domestication and the first village at Mehrgarh.
- Civilisations: the Sindhu-Sarasvati cities and the Bronze Age civilisations of Mesopotamia, Egypt and China.
The chapter mixes timelines, maps and short definitions, so studying it from the original book helps students learn the exact terms examiners look for.
Topics and Sections Inside the Class 9 Chapter 4 NCERT Book PDF
The book PDF follows the historical order, so students see how one change led to the next. The table below lists the main topics in the chapter.
| Topic | What it teaches |
|---|---|
| Before Writing | Why writing divides history; how archaeologists study tools, fossils and cave art. |
| Human Ancestors | Biological and cultural evolution, and the spread of humans out of Africa. |
| Palaeolithic and Mesolithic | Hunter-gatherers, handaxes, tiny microlithic tools and rock paintings. |
| Neolithic Revolution | Domestication, the move to farming, and Mehrgarh as the earliest farming village. |
| Sindhu-Sarasvati Civilisation | Planned Harappan cities, crafts, standard weights and water management. |
| Bronze Age Civilisations | Mesopotamia, Egypt and China, and their gifts like cuneiform and the calendar. |
Each section carries labelled figures, timelines and short "revisit" prompts, so students can follow the story straight from the textbook.
Key Terms in the Early Humans and Beginning of Civilisation Chapter
The chapter is built around a small set of terms that come up again and again in the exam. The book PDF defines each one in simple words.
| Term | Meaning |
|---|---|
| Fossil | Preserved remains of plants, animals or humans slowly turned to stone. |
| Hominin | A tool maker; modern humans and their tool-making ancestors. |
| Domestication | Taming and breeding plants and animals for human use. |
| Neolithic Revolution | The shift from hunting and gathering to farming and herding. |
| Ziggurat | A stepped temple tower at the centre of a Sumerian city. |
| Cuneiform | Sumerian wedge-shaped writing pressed into clay tablets. |
The Harappan script is still undeciphered, so we know the Harappans mainly through their buildings, seals and objects. Facts like this appear right where the book introduces early writing, which makes the PDF easy to revise from.
