Evolution

 

 

Charles Darwin

Charles DarwinThe theory of evolution is based on the ideas of English scientist Charles Darwin. In 1831, Darwin sailed around the world and studied plants, animals, and rocks. On his trip, he began to wonder if some of the animals he saw had the same ancestors.

Darwin explained his ideas in a book called On the Origin of Species, published in 1859. This cartoon shows that people laughed at Darwin's idea that humans were related to apes.

 

Alfred Wallace

 

 

Although Darwin gets credit for the theory of evolution, he wasn't the only one to think of it. Alfred Wallace, another English scientist, put forth a very similar theory just before Darwin's book was published.
