Charles Darwin is widely regarded as the scientist who formulated the theory of evolution by natural selection. This groundbreaking theory has revolutionized the way we understand the diversity of life on earth.

The Life of Charles Darwin

Charles Darwin was born in 1809 in England. He was a naturalist, biologist, and geologist who spent many years studying and observing the natural world.

In 1831, Darwin set sail on a voyage around the world aboard the HMS Beagle. During this five-year journey, he collected specimens and made detailed observations of plants and animals. These experiences would shape his thinking for the rest of his life.

The Theory of Evolution by Natural Selection

Darwin’s most famous work, On the Origin of Species, was published in 1859. In this book, he introduced his theory of evolution by natural selection.

The basic idea behind natural selection is that organisms that are better adapted to their environment are more likely to survive and reproduce. Over time, these advantageous traits become more common in a population, leading to evolutionary change.

This theory challenged traditional views about the origins of life and sparked controversy among scientists and religious leaders alike.

Impact on Science

Despite the initial backlash, Darwin’s theory has had a profound impact on science and our understanding of biology. It has been supported by numerous lines of evidence from fields such as genetics, paleontology, and biogeography.

Today, evolution by natural selection is widely accepted as a fundamental principle in biology. It has helped us understand how species have changed over time and how they continue to adapt to changing environments.


In conclusion, Charles Darwin is credited with formulating the theory of evolution by natural selection. This groundbreaking idea has changed our understanding of life on earth and continues to be an important area of research in the biological sciences.
