Despite challenges, Galileo continued his research. He wrote books explaining his ideas that are still studied today.
Galileo’s curiosity and careful observations helped start the scientific revolution. He showed the importance of testing ideas through experiments.
5) Charles Darwin
Charles Darwin was an English scientist born in 1809. He became famous for his ideas about how living things change over time.
Darwin’s most important idea was called the theory of evolution by natural selection. This theory explains how species adapt to their environments and change over many generations.
As a young man, Darwin went on a five-year voyage around the world on a ship called HMS Beagle. During this trip, he studied plants, animals, and fossils in different places.
Darwin noticed that similar animals on different islands had small differences. This made him think about how species might change.
After returning home, Darwin spent many years studying his findings. He wrote a book called “On the Origin of Species” that explained his ideas about evolution.
Darwin’s work changed how scientists think about life on Earth. His theories are still important in biology today.
