Charles Darwin was another important scientist of the past 1,000 years. He was born in England in 1809. In 1859, he published a book called On the Origin of Species by Means of Natural Selection. He explained his ideas that all living things developed from simple organisms. He said these organisms changed during millions of years to produce different kinds of plants and animals, including humans. This is known as the theory of evolution. Charles Darwin's studies showed that some animals and plants have natural abilities that help them survive. They pass these abilities to their young when they reproduce. Other plants and animals that are less able to survive and reproduce may disappear. Charles Darwin's theories provided new ideas about the developments of living things.

He discovered that heat could kill harmful microorganism. Soon this Pasteurization method was used to keep many foods and drinks safe. He also helped us establish the germ theory when he recognized that most diseases are spread by tiny organisms that reproduce in the body. Louis Pasteur also proved that an animal can develop a resistance to a harmful organism if the organism is weekend in a laboratory and injected into the animal's body. He called this method of preventing disease vaccination. He developed vaccines to prevent deadly diseases in animals and people.

They are only three of the many devices Thomas Edison invented or helped to improve. H e also invented devices to improve the telephone. He improved machines that produced electricity.
