Did You Know? (āĻিāĻŦা āĻাāύাāύে?)
Chimpanzees are one of our closest living relatives in the animal kingdom. They share about 98.8% of their DNA with humans, which is why their actions, like peeling a banana, look so much like ours!
đ Quick Chapter Summary
In this interesting lesson, a young girl named Jharna goes to the zoo with her father. She sees many animals, but she is most amazed by two chimpanzees because their actions look just like humans. Her father then tells her the fascinating story of our early ancestors (primitive people). He explains how early humans lived in jungles like animals, but slowly used their intelligence and thinking ability to build houses, grow crops, and start human civilization.

The environment inside was nature-friendly.
āĻিāϤ⧰⧰ āĻĒā§°িā§ąেāĻļ āĻĒ্ā§°āĻৃāϤি-āĻ āύুāĻূāϞ āĻāĻিāϞ।
There were many big trees all around.

There was also a park inside the zoo.
āĻিā§°িāϝ়াāĻাāύাā§° āĻিāϤ⧰āϤ āĻāĻāύ āĻĒাā§°্āĻো āĻāĻিāϞ।

She was very excited and happy.
āϤাāĻ āĻŦāĻšুāϤ āĻā§āϏাāĻšিāϤ āĻā§°ু āϏুāĻী āĻāĻিāϞ।
Suddenly Jharna's attention was caught by the sound of laughter from a crowd nearby.

"Something interesting is going on there," she thought.
"āϤাāϤ āĻিāĻŦা āĻāĻā§°্āώāĻŖীāϝ় āĻāĻি āĻāĻে," āϤাāĻ āĻাāĻŦিāϞে।
She was very curious.
āϤাāĻ āĻŦāĻšুāϤ āĻৌāϤূāĻšāϞী āĻāĻিāϞ।
She almost dragged her father to see what was going on.

She saw that the people were laughing and enjoying the activities of the two chimpanzees which were kept there.

There was a swing and one chimpanzee was swinging while the other one was pushing the swing.
āϤাāϤ āĻāĻāύ āĻĻোāϞāύা āĻāĻিāϞ āĻā§°ু āĻāĻা āĻিāĻŽ্āĻĒাāĻ্āĻীāϝ়ে āĻĻুāϞি āĻāĻিāϞ āĻāύāĻšাāϤে āĻāύāĻোā§ąে āĻĻোāϞāύাāĻāύ āĻ েāϞি āĻĻিāĻিāϞ।
Both of them were enjoying themselves.
āĻĻুāϝ়োāĻাāĻ āύিāĻāĻে āĻāĻĒāĻোāĻ āĻā§°ি āĻāĻিāϞ।
After a while, a caretaker gave them some bananas.

The chimpanzees came near the fence and took the bananas.

Then they started eating them, peeling off the skin like humans.
āϤাā§° āĻĒিāĻāϤ āϏিāĻšঁāϤে āĻŽাāύুāĻšā§° āĻĻā§°ে āĻŦাāĻāϞি āĻুāĻাāĻ āϏেāĻāĻŦোā§° āĻাāĻŦāϞৈ āϧ⧰িāϞে।
"Their actions are so much similar to ours!" exclaimed Jharna in wonder.

"Yes, my dear. They are very close to the homo sapiens who were our ancestors." Jharna's father said.

Jharna's father began, "Thousands of years ago, our ancestors, the primitive people lived in jungles.

Like other animals they ate fruits, hunted animals and caught fishes for their food.

They could not build houses.

So they took shelter in caves or under big trees when it rained.
