CBSE Class 11 History Notes — From the Beginning of Time

CBSE Class 11 History Chapter 1 notes: human evolution, Australopithecus and Homo, early tools, fire, cave art, hunter-gatherers and the shift to farming.

Chapter Summary

This chapter follows humanity from the first hominids in Africa about 5.6 million years ago to the dawn of farming. It explains how fossils, tools and cave art are interpreted, how Australopithecus gave way to Homo, the two models of modern human origins, early food, shelter, fire, language and art, and whether living hunter-gatherers such as the Hadza can explain the past.

Key Concepts

Setting the Stage: Early Societies and the Long Road to Settled Life

The opening pages of Unit I place the chapter inside a much bigger story. For millions of years our ancestors lived by moving across landscapes, sleeping in forests, caves and temporary shelters, and collecting what nature offered. The first great change came only about 10,000 years ago, when people in some regions began to grow crops and keep animals. Wheat, barley, peas and pulses were grown in West Asia, millet and rice in East and Southeast Asia, and millet in Africa. Sheep, goat, cattle, pig and donkey were domesticated.

Once people had to wait for crops to ripen, they stayed in one place, built sturdier houses, made clay pots for storing and cooking grain, and polished stone tools by grinding. Some learnt to use copper and tin ores, and goods such as shell, obsidian and precious stones travelled long distances. By about 5,000 years ago cattle and donkeys were harnessed to ploughs and carts, and trade and larger settlements led to small states and then the first cities. Some scholars call this transformation a revolution.

The unit also teaches you how to read a timeline. Dates for ordinary people's work are harder to fix than the dates of wars, historians keep revising dates, blank spaces often mean we simply do not know, and regional columns overlap. Keep this in mind whenever you quote a date in an answer.

How We Know: Fossils, Dating and the Struggle to Be Believed

Our knowledge of early humans comes mainly from fossils, stone tools and cave paintings. Fossils are the stony remains or impressions of ancient plants, animals and humans, often preserved in rock. They can be dated by chemical analysis of the bone itself or indirectly by dating the layers of sediment in which they lie, which is why the exact position of a find is carefully recorded with grids and measuring frames. Once many fossils are dated, a sequence of human evolution can be worked out.

A surprising point in this chapter is how reluctantly scholars accepted such evidence. About 200 years ago many believed in the Biblical account of creation and could not imagine that these remains belonged to earlier forms of humans. In August 1856 workmen quarrying limestone in the Neander valley near Dusseldorf found a skull and bones. Carl Fuhlrott, a local schoolteacher, recognised that they were not modern, and with the anatomist Herman Schaaffhausen published the claim a year later. Other scholars rejected it and called the skull a recent and diseased one.

The publication of Charles Darwin's On the Origin of Species on 24 November 1859 gave the debate a major push, though acceptance came slowly. The lesson for a history student is that evidence does not interpret itself; interpretation depends on the ideas of the time.

From Primates to Hominids: The Precursors of Humans

To imagine the scale of time, picture a book in which each page equals 10,000 years: 36 million years would need a book of 3,600 pages. It was between 36 and 24 million years ago (mya) that primates, a group of mammals including monkeys, apes and humans, emerged in Asia and Africa. By about 24 mya a subgroup called hominoids, which includes apes, appeared. Around 5.6 mya we find the first hominids.

Hominoids have smaller brains, walk on all fours with flexible forelimbs, and have no human-like hand. Hominids have larger brains, walk upright on two legs (bipedalism) and have hands that can make and use tools. Two clues point to Africa as their homeland: the African apes are the closest relatives of hominids, and the oldest hominid fossils, of the genus Australopithecus, come from East Africa and date to about 5.6 mya. Fossils outside Africa are no older than about 1.8 million years.

Hominids are divided into genera, chiefly Australopithecus and Homo. Australopithecus (southern ape) had a smaller brain, heavier jaws and larger teeth, and still kept long forelimbs, curved hand and foot bones and mobile ankles suited to climbing trees. Homo has a bigger brain, smaller teeth and less protruding jaws. Species names usually come from Latin and Greek words.

Bipedalism, Climate Change and the Positive Feedback Mechanism

Why did walking on two legs and tool use develop? The chapter explains this through the positive feedback mechanism: one development strengthens another, which in turn strengthens the first. Bipedalism freed the hands to carry infants and objects; as hands were used more, upright walking became more efficient. Walking on two feet also uses less energy than moving on four, although this advantage is lost when running.

Evidence for bipedalism is both indirect and direct. Fossilised hominid footprints at Laetoli in Tanzania, about 3.6 mya, are indirect proof. Limb bones from Hadar in Ethiopia give direct proof. Tool making, a bigger brain and better hand control joined the same loop, so that tools, hands and brains developed together.

Around 2.5 mya a glaciation, or Ice Age, began. Temperatures and rainfall fell, grasslands spread at the cost of forests, and the forest-adapted forms of Australopithecus gradually became extinct. They were replaced by species that suited drier conditions, among them the earliest members of the genus Homo. Australopithecus is shown as becoming extinct around 1.3 mya in the chapter's timeline.

The famous find at Olduvai Gorge on 17 July 1959 is also linked here. Mary Leakey, who directed excavations at Olduvai and Laetoli, found the teeth of an early hominid after a search of 23 years with her husband Louis Leakey.

The Genus Homo and the Peopling of the World

Homo is Latin for man. Scientists identify several species by typical features or find-places. Homo habilis, the tool maker, appears about 2.2 mya, with fossils from Omo in Ethiopia and Olduvai Gorge in Tanzania. Homo erectus, the upright man, dates from about 1.8 mya and survived for nearly a million years; its earliest fossils come from Koobi Fora and West Turkana in Kenya and from Modjokerto and Sangiran in Java. Because the Asian finds are later than the African ones, hominids probably migrated out of East Africa between 2 and 1.5 mya, spreading to southern and northern Africa, parts of Asia and perhaps Europe.

Homo heidelbergensis (named after Heidelberg, Germany) and Homo neanderthalensis (from the Neander valley) are called archaic Homo sapiens. Heidelbergensis, dated about 0.8-0.1 mya, is found in Africa, Asia and Europe. Neanderthals lived in Europe and western and Central Asia from about 130,000 to 35,000 years ago and disappeared abruptly from western Europe.

Compared with Australopithecus, Homo have larger brains, which is linked to better intelligence and memory, and smaller teeth and jaws, probably reflecting a change in diet. The chapter's peopling table shows Africa first (5-1 mya), then Africa, Asia and Europe in mid-latitudes, Australia about 45,000 years ago, and later high-latitude Europe, the Asia-Pacific islands and the Americas.

Modern Humans: Regional Continuity versus Replacement

The earliest fossils of modern humans (Homo sapiens sapiens) come from many African sites. Omo Kibish in Ethiopia gives dates of 195,000-160,000 years ago; South African sites like Border Cave and Klasies River Mouth are 120,000-50,000 years old; there are also finds from Morocco, Israel (Qafzeh, Skhul), Lake Mungo in Australia, Niah Cave in Borneo and Cro-Magnon in France (about 35,000 years ago). Since so many early finds are African, scholars ask whether modern humans arose in one place or several.

The regional continuity model says that archaic Homo sapiens in different regions evolved at different rates into modern humans. It explains why modern humans appear at different times in different regions and uses the physical differences between present-day populations, which it traces back to earlier Homo erectus and heidelbergensis groups living in the same areas.

The replacement model argues for a single origin in Africa, after which modern humans replaced all older forms everywhere. It relies on the genetic and anatomical similarity of all people today and on the early Omo fossils. Supporters explain present physical differences as adaptation to local conditions over thousands of years by groups who migrated to different places.

For board answers, state both models, give one piece of evidence for each, and mention that the debate is still open. Note that the chapter's introduction says modern humans originated about 160,000 years ago, while Timeline 2 gives 195,000-160,000 years ago.

Getting Food, Finding Shelter and Using Fire

Early humans obtained food by gathering, scavenging, hunting and fishing. Gathering of seeds, nuts, berries, fruits and tubers is mostly assumed, because fossilised plant remains are rare and carbonised seeds from this early period have hardly been found. Many scholars now think the earliest hominids scavenged meat and marrow from animals killed by others or dead naturally, and also ate small animals, eggs and insects. Deliberate planned hunting of large animals came later, with clear evidence from Boxgrove in England (about 500,000 years ago) and Schoningen in Germany (about 400,000 years ago). Fish bones show fishing was also important. By about 35,000 years ago, sites like Dolni Vestonice in the Czech Republic suggest that hunters chose places near rivers to kill herds of migrating reindeer and horse.

Shelter is better documented. Thousands of tools at Kilombe and Olorgesailie in Kenya (700,000-500,000 years ago) suggest repeated visits to food-rich spots. Between 400,000 and 125,000 years ago caves and open-air sites were used, such as a 12 by 4 metre shelter against a cave wall at Lazaret and seasonal huts at Terra Amata in southern France.

Baked clay and burnt bone from Chesowanja and Swartkrans (1.4-1 mya) may come from natural fires. Hearths, about 125,000 years ago, show controlled fire, which gave warmth, light and cooked food, hardened spear tips, helped flake tools and kept animals away.

Making Tools: From Choppers to Blades and Needles

Tool use is not confined to humans, since some chimpanzees and birds make objects for feeding. What distinguishes human tool making is the skilled hand, memory and organisational ability needed to plan and produce tools. The earliest stone tools, about 2.6-2.5 mya, come from Ethiopia and Kenya and were probably made by Australopithecus. Early examples from Olduvai include the chopper, a large stone with flakes removed to make an edge, and the hand axe. We cannot say whether men, women or both made them; women may well have made tools to find food for themselves and for children after weaning.

About 35,000 years ago new tool kits appeared. The spear-thrower and the bow and arrow made killing from a distance more effective. Meat could be processed by removing bones, drying, smoking and storing, so food could be kept for later. Fur-bearing animals were trapped for clothing, and sewing needles were invented, with evidence of sewn clothing about 21,000 years ago.

The punch blade technique produced small chisel-like tools, such as burins, with which people could engrave designs on bone, antler, ivory or wood. In the technique, a hammer stone removes the top of a pebble to make a flat striking platform, which is struck with a bone or antler punch to detach blades. Tool making was therefore both an economic and an artistic step.

Language, Cave Art and the Mystery of Altamira

Humans alone among living beings have language. Scholars offer different ideas of how it began: through gestures, through singing or humming before speech, or from calls like those of other primates. As for timing, one view says that the brain of Homo habilis was already capable of speech, so language could be as old as 2 mya. Another links it to the evolution of the vocal tract about 200,000 years ago, in modern humans. A third connects it to the emergence of art about 40,000-35,000 years ago, since both are ways of communicating.

Cave art is rich evidence. At Altamira in Spain, in November 1879, Maria, the young daughter of the amateur archaeologist Marcelino Sanz de Sautuola, looked up and noticed paintings of oxen on the ceiling. His 1880 booklet was dismissed for almost twenty years because experts thought the paintings were too good to be ancient. Hundreds of paintings of bison, horses, ibex, deer, mammoths, rhinos, lions, bears and other animals, made between 30,000 and 12,000 years ago, are known from Lascaux and Chauvet in France and from Altamira.

Many questions remain. Why are only some parts of caves painted? Why are men shown with animals but women are not? Explanations include ritual or magic to secure a successful hunt, and the idea that caves were meeting places where knowledge was passed on through paintings and engravings.

Living Hunter-Gatherers and the Past; the Epilogue on Farming

The chapter ends by asking whether present-day hunter-gatherers can help us understand the past. Anthropologists have written about groups like the Hadza of Tanzania, who live near Lake Eyasi, claim no private rights over land, move camps with the seasons and rely on roots, berries and honey for about 80 per cent of food by weight, so they never face shortage even in drought. Hunting is a smaller part of their diet. The !Kung San of the Kalahari were met by pastoral neighbours in 1870 and avoided them.

One group of scholars applies such observations directly to archaeology; for instance, they suggest that sites near Lake Turkana dated 2 mya might have been dry-season camps, as with the Hadza and !Kung San. Others disagree: today's foragers trade forest produce, work for farmers and are marginalised, so their world differs from that of early humans. They also vary widely in group size, mobility and the division of labour, although women usually gather and men hunt in many cases, and women's contribution is important.

The epilogue explains the shift to farming. The last Ice Age ended about 13,000 years ago, warmer, wetter conditions spread, wild wheat and barley and animals such as sheep, goat and cattle increased, and population pressure encouraged domestication, first in the Fertile Crescent about 10,000 years ago. This led to villages, pottery and metals, and then to cities about 5,000 years ago.

Frequently Asked Questions

What is the difference between hominoids and hominids?

Hominoids, including apes, have smaller brains, walk on all fours and have flexible forelimbs. Hominids, which include all human forms, have larger brains, walk upright on two legs and have a specialised hand for making tools. Hominoids appeared about 24 mya, while the first hominids appeared about 5.6 mya, probably in Africa.

Why is Africa believed to be the place of origin of hominids?

There are two reasons. The African apes are the closest relatives of hominids, and the earliest hominid fossils, of Australopithecus, come from East Africa and date to about 5.6 mya. Fossils found outside Africa are no older than about 1.8 million years, which suggests later migration from Africa.

Explain the positive feedback mechanism in human evolution.

It is a process in which one development strengthens another, which then reinforces the first. For example, walking upright freed the hands for carrying and tool use; more use of hands made upright walking more efficient and helped the brain and tool making advance. Together these changes gradually produced distinctive human features.

Why did the Neanderthal skull found in 1856 and the Altamira paintings face rejection?

Many scholars then believed in the Biblical idea of creation and doubted that humans had such a long past. The Neanderthal skull was said to belong to a recent or diseased person. The Altamira paintings were thought too good to be ancient, so Sautuola's claim was dismissed for nearly two decades.

Compare the regional continuity and replacement models of modern human origins.

Regional continuity holds that archaic Homo sapiens in several regions evolved gradually into modern humans, explaining regional differences. The replacement model says modern humans originated in Africa and replaced older humans everywhere, and local differences arose through later adaptation. Genetic and anatomical similarity and the early Omo fossils support replacement.

How did the use of fire help early humans?

Fire gave warmth and light inside caves, allowed food to be cooked, hardened wooden spear tips and helped in flaking stone tools. It also scared away dangerous animals. Hearths, dated to about 125,000 years ago, are clear signs of controlled use, whereas burnt clay and bones from earlier sites could be natural.

What were the possible purposes of cave paintings?

Scholars offer two main explanations. First, since hunting mattered, painting animals may have been a ritual or form of magic to ensure a successful hunt. Second, caves may have been meeting places where groups shared hunting methods, and paintings and engravings passed knowledge from one generation to the next.

Can present-day hunter-gatherer societies help us understand early humans? Give both views.

Some scholars apply Hadza and !Kung San practices, such as dry-season camps, to interpret old sites. Others argue that today's foragers trade, work for farmers and live on society's margins, and that they vary greatly, so they differ from early humans. A cautious approach treats such data as suggestive, not conclusive.

Why did people begin farming about 10,000 years ago?

The last Ice Age ended about 13,000 years ago and warmer, wetter weather increased wild wheat, barley and animals like sheep and goat. People settled in rich areas and population pressure grew. A mix of climate change, population pressure and growing knowledge of a few plants and animals led to domestication.

Why are dates in a timeline described as tentative?

Historians keep revising dates when new evidence or new methods of assessing old data emerge. Long processes involving ordinary people are harder to date than events like wars, and blank spaces in a timeline can mean that we do not yet know what was happening, not that nothing happened.
