Welcome to Explore the World and Education. Today, we will be talking about Grade 10 History, second lesson, Ancient Settlements. So let's get started.
Grade 10 History lesson on Ancient Settlements in Sri Lanka covering human habitation, Stone Age evidence, and environmental adaptation.
Key Takeaways
- Homo Sapiens migrated to and settled in Sri Lanka over 125,000 years ago.
- Sri Lanka's prehistoric human history is divided into distinct cultural stages, with the Stone Age as a major period.
- Environmental zones shaped the lifestyle, diet, and technology of early human communities.
- Archaeological evidence such as stone tools and animal bones provide insight into early human life in Sri Lanka.
- Understanding ancient settlements helps explain human adaptation to diverse climatic conditions.
Summary
- Sri Lanka became a human habitation around 125,000 years ago with Homo Sapiens migrating across the Indian Ocean.
- The history of human existence in Sri Lanka is divided into three cultural stages based on changes in culture.
- The pre-historic era in Sri Lanka consists of two cultural stages, with the Stone Age being the first and longest stage.
- Early Homo Sapiens in Sri Lanka adapted to various climatic zones and depended mainly on gathering and hunting for food.
- Stone Age evidence is found in places like Ratnapura, where stone tools and extinct animal bones were discovered in gravel layers.
- The Iranamadu formation is a gravel layer in the semi-arid zone containing Stone Age tools, deposited during the Pleistocene era.
- Stone Age communities lived in six main environmental zones in Sri Lanka, classified mainly by annual rainfall differences.
- Different environmental zones influenced the food consumption and technology of Stone Age people.
- In the lowland wet zone, Stone Age people mainly consumed oysters, while in the lowland dry zone, they hunted animals like deer and iguana.

Speaker A
Our first topic is Human Habitation in Sri Lanka.
Speaker A
When did Sri Lanka become a human habitation?
Speaker A
Sri Lanka became a human habitation 125,000 years ago.
Speaker A
Who migrated to Sri Lanka across the Indian Ocean?
Speaker A
The Homo Sapiens, who are called the modern man, migrated to this country across the Indian Ocean.
Speaker A
How did the Homo Sapiens adapt after migrating to Sri Lanka?
Speaker A
They spread themselves in various parts of this country and adapted themselves to different environmental conditions in those areas.
Speaker A
How did the culture of Homo Sapiens change over time in Sri Lanka?
Speaker A
As they lived a considerably long time period in this country, with time their culture too changed.
Speaker A
Into how many stages is the history of human existence in Sri Lanka divided?
Speaker A
Based on changes in their culture, the history of human existence in Sri Lanka has been divided into three stages.
Speaker A
Okay, now let's talk about Prehistoric and Proto-Historic Era of Sri Lanka.
Speaker A
What is the period before the past described by literary sources commonly named?
Speaker A
The period before the past that is described by the literary sources is commonly named as 'the pre-historic era'.
Speaker A
How many cultural stages belonged to the pre-historic era of Sri Lanka?
Speaker A
Two cultural stages belonged to the pre-historic era of Sri Lanka.
Speaker A
What was the first cultural stage of the pre-historic era?
Speaker A
The first cultural stage was the Stone Age, which existed for a long time.
Speaker A
Who made the early settlements in Sri Lanka?
Speaker A
Settlements in Sri Lanka were made by the early Homo Sapien man.
Speaker A
How did the Homo Sapien expand his living area in Sri Lanka?
Speaker A
Homo Sapien expanded his living in a wide geographical area by adapting himself to different climatic zones in this country.
Speaker A
What was the main dependency method of the early Homo Sapiens in Sri Lanka?
Speaker A
Their main dependency method was gathering food by roaming and hunting.
Speaker A
Now let's talk about Evidence of the Stone Age in Sri Lanka.
Speaker A
Where is the evidence of the Stone Age in Sri Lanka found?
Speaker A
Evidence of the Stone Age in Sri Lanka is found in many places, including Ratnapura and the gem mines located around Ratnapura.
Speaker A
What is deposited in the gravel layers found in Ratnapura's mines?
Speaker A
The stone tools used by these people who lived in a distant age and the bones of some extinct animals are deposited in the layers of soil mixed with gravel, called lode, found in the mines about 90 feet deep from the ground level.
Speaker A
How were the gravel layers in Ratnapura formed?
Speaker A
The gravel layers were caused by the erosion of mountainous regions due to extremely heavy rainy periods during the Pleistocene geographical era and were deposited on the lowlands in this manner.
Speaker A
What is the Iranamadu formation?
Speaker A
The Iranamadu formation is a gravel layer covered with sandy soil mixed with clay in the ground in the semi-arid zone in Sri Lanka, named by archaeologists.
Speaker A
When was the Iranamadu formation deposited?
Speaker A
The Iranamadu formation was deposited during the short warm periods of the Pleistocene era.
Speaker A
What tools are found in the Iranamadu formation?
Speaker A
Some tools which belonged to the Stone Age are found in this gravel layer.
Speaker A
Now let's talk about Expansion of Settlements in Different Climate Zones.
Speaker A
How many main environmental zones did the community of the Stone Age live in Sri Lanka?
Speaker A
The community of the Stone Age lived in six main environmental zones in Sri Lanka.
Speaker A
What are the six main environmental zones where the Stone Age community lived?
Speaker A
The six main environmental zones are: (A) Semi-arid zone, (B) Lowland dry zone, (C) Lowland intermediate dry zone, (D) Wet zone, (E) Mountainous dry intermediate zone, (F) Arid zone.
Speaker A
Now let's talk about Environmental Zones and Their Impact.
Speaker A
What factor is considered in deciding environmental zones?
Speaker A
The differences in annual rainfall levels are considered in deciding environmental zones.
Speaker A
How does rainfall affect environmental zones?
Speaker A
If there is a difference in the rainfall, it directly affects the animals and the plants in that particular area.
Speaker A
How did people in the Stone Age adapt to different environmental zones?
Speaker A
The people in the Stone Age who adapted themselves to different environmental zones had differences in their food consumption and technology.
Speaker A
What type of food did the Stone Age community in the lowland wet zone consume? The Stone Age community in the lowland wet zone mostly consumed oysters living on the land as their food.
Speaker A
Why were oysters abundant in the lowland wet zone?
Speaker A
Different types of oysters are abundant in the lowland wet zone due to its environmental conditions.
Speaker A
What types of food did the Stone Age community in the lowland dry zone consume?
Speaker A
In the lowland dry zone, people hunted animals, mostly living in the dry zone, like deer and iguana.
