T

F

B. Fill in the blanks.

A dinosaur is an ......................... animal. (endangered/extinct)
Early humans, who could not stand straight were called ......................... (humans/hominids)
The earliest human beings lived in ......................... (Africa/India)
......................... gained the ability to hold objects. (Homo habilis/Homo sapiens)
Note: While Homo habilis, "handy man," was an earlier species known for tool use, the text specifically mentions that as hominids changed over many years, "they developed features that we see in humans today. For instance, they could stand upright and gained the ability to hold objects." and "The present species of humans are called homo sapiens." The timeline also shows Homo sapiens as the most developed.

C. Answer these questions in brief.

Who were hominids?
Hominids were early human-like beings who lived about two million years ago, resembled apes, had big, sloped heads, small foreheads, long arms up to knees, thick hair all over body, and could not stand upright or speak.
What would early humans use their hands for?
Early humans used their hands to make tools, pick up things, and throw them.
How would early humans dress?
Early humans wore animal skins and used leaves to cover themselves.
Why did early humans move from one place to another?
Early humans moved from one place to another in search of food, such as animals to hunt, fruits, and roots.

D. Answer these questions in detail.

How did a hominid change over the years?
Over many years, hominids underwent significant changes. They gradually developed the ability to stand upright and walk on two feet. Their brains became larger, which increased their intelligence. Their hands evolved to allow them to make and use tools effectively, pick up objects and throw them. These changes transformed them from ape-like creatures into the species we know today as Homo sapiens.
How do you think the ability to walk upright helped humans?
The ability to walk upright helped humans in several important ways. It freed their hands, allowing them to carry food, tools, or their young while moving. Standing upright also gave them a better view of their surroundings, helping them spot food sources or dangers from a distance. Furthermore, walking on two legs is a more energy-efficient way to travel long distances compared to walking on all fours.
Describe the life of a hunter-gatherer.
Hunter-gatherers led simple, nomadic lives. They moved from place to place in search of food, hunting animals, catching fish, and gathering edible plants like fruits and roots. When food became scarce in one area, they would move to a new location. For protection from wild animals and the elements, they lived in caves or on tree tops. They used animal skins and leaves for clothing.
What are the different sources of information for early humans?
We learn about early humans from various sources. These include caves and rock shelters where they lived, which sometimes contain cave paintings. Tools and artefacts, such as pottery, made and used by them provide clues about their skills and daily activities. Fossils (remains of living things or their impressions on rocks), along with bones and horns of animals found at ancient sites, also give us valuable information about their diet and the environment they lived in.

Picture Study

Look at the picture and answer these questions.
What does this cave painting depict?
This cave painting depicts scenes from the lives of early humans, likely showing hunting activities with figures of humans and animals like deer.
Who do you think made these paintings?
Early humans, possibly hunter-gatherers, made these paintings inside caves.
Name two places in India where these paintings can be seen.
In India, we can see this type of painting in
Bhimbetka in Madhya Pradesh
Ajanta caves in Maharatra
Jogimara Caves in Madhya Pradesh

Life Skills and Values

Give two ways in which the early humans adapted to their environment? How do people adapt to their environment now?
Two ways early humans adapted to their environment were:
Shelter: They used caves or lived on tree tops to protect themselves from wild animals and harsh weather.
Clothing: They used animal skins and leaves to cover their bodies for warmth and protection.
People now adapt to their environment in many ways, such as:
Housing: Building houses with heating, cooling, and insulation suitable for the local climate.
Clothing: Wearing specialized clothing for different weather conditions (e.g., waterproof jackets for rain, thermal wear for cold).
Technology: Using technology like air conditioning (AC), transportation, and advanced food production and preservation methods to manage environmental challenges.
