English naturalist, geologist and biologist, best known for his contributions to the science of evolution.

Early life and education
Charles Darwin was born on February 12, 1809, in Shrewsbury, England. He was the fifth of six children born to Robert Darwin, a wealthy physician, and Susannah Wedgwood Darwin. Darwin's grandfather, Erasmus Darwin, was a well-known naturalist and poet.
Darwin showed an early interest in natural history. He collected insects, plants, and shells as a child. He also enjoyed fishing and hunting.
In 1825, Darwin entered the University of Cambridge to study medicine. However, he found the medical courses to be boring and uninspiring. He much preferred studying natural history.
In 1828, Darwin took a break from his studies to take a voyage on the HMS Beagle. The Beagle was a British Navy ship that was surveying the coast of South America. Darwin served as the ship's naturalist.

The Voyage of the Beagle
The Voyage of the Beagle lasted for five years. During that time, Darwin had the opportunity to observe a wide variety of plants and animals. He was also struck by the similarities and differences between the species he saw in different parts of the world.
One of the most important stops on the Beagle's journey was the Galapagos Islands. The Galapagos Islands are a group of volcanic islands located off the coast of Ecuador. Darwin was impressed by the diversity of life he found on the Galapagos Islands. He noticed that there were different species of finches on different islands. He also noticed that the finches on each island were well-adapted to their environment.

The theory of evolution
After returning to England in 1836, Darwin began to work on a theory to explain the diversity of life on Earth. He knew that species could change over time, but he didn't know how this happened.
In 1858, Darwin received a letter from Alfred Russel Wallace. Wallace was a British naturalist who had also developed a theory of evolution. Darwin and Wallace's theories were very similar. They both proposed that species evolved through a process of natural selection.

Natural selection
Natural selection is the process by which organisms that are better adapted to their environment are more likely to survive and reproduce. This means that the traits that help organisms survive and reproduce will become more common in a population over time.
Darwin published his theory of evolution in 1859 in a book called On the Origin of Species. The book was a huge success. It quickly sold out and was translated into many languages.

The Origin of Species
On the Origin of Species is one of the most important books in the history of science. It revolutionized our understanding of the natural world. Darwin's theory of evolution has been supported by a great deal of evidence since it was first published.

Darwin's legacy
Charles Darwin died on April 19, 1882. He was 73 years old. He is buried in Westminster Abbey, London.
Darwin's legacy is immense. His theory of evolution is one of the cornerstones of modern science. It has helped us to understand the diversity of life on Earth, the history of life, and our own place in the natural world.

The Theory of Evolution

The process by which organisms change over time as a result of changes in heritable physical or behavioral traits.

History of evolutionary theory
The theory of evolution is one of the most important and well-supported theories in science. It is based on the idea that all living things are related to each other, and that they have changed over time from common ancestors.
The first person to propose a theory of evolution was Jean-Baptiste Lamarck. Lamarck was a French naturalist who lived in the 18th century. He believed that organisms could inherit characteristics that their parents had acquired during their lifetime. For example, he thought that a blacksmith's son would have strong arms because his father had used his arms so much.
Lamarck's theory was not widely accepted, but it paved the way for the work of Charles Darwin. Darwin was a British naturalist who lived in the 19th century. He is best known for his book On the Origin of Species, which was published in 1859.

Darwin's theory of evolution
Darwin's theory of evolution is based on the principle of natural selection. Natural selection is the process by which organisms that are better adapted to their environment are more likely to survive and reproduce. This means that the traits that help organisms survive and reproduce will become more common in a population over time.
Darwin's theory of evolution was supported by a great deal of evidence, including the fossil record, the geographic distribution of organisms, and the similarities between different species.

The modern theory of evolution
The modern theory of evolution is a synthesis of Darwin's theory of natural selection with the principles of genetics. Genetics is the study of how traits are passed down from parents to offspring.
The modern theory of evolution explains how organisms can change over time as a result of changes in their genes. Genes are the units of heredity that are passed down from parents to offspring.

Evidence for evolution
There is a great deal of evidence to support the theory of evolution. This evidence includes:

The fossil record: The fossil record is the record of past life on Earth. Fossils show that organisms have changed over time.
The geographic distribution of organisms: The geographic distribution of organisms is the pattern of where different species live. This pattern can be explained by the theory of evolution.
The similarities between different species: The similarities between different species can be explained by the theory of evolution.

The theory of evolution is a powerful tool that can be used to understand the natural world. It has helped us to understand the diversity of life on Earth, the history of life, and our own place in the natural world.

In 1831, Darwin set sail on the HMS Beagle for a five-year voyage around the world. During the voyage, Darwin collected specimens of plants and animals, and made detailed observations of the natural world.

In 1871, Darwin published another book called The Descent of Man. In this book, Darwin applied his theory of evolution to humans. He argued that humans are descended from apes, and that we share a common ancestor with chimpanzees and gorillas.

The Impact of Darwin's Theory
Darwin's theory of evolution has had a profound impact on our understanding of the natural world. It has helped us to understand the diversity of life on Earth, the history of life, and our own place in the natural world.
