He was keen for his ideas to reach as many people as possible and for his books to be read in many different languages. Part of his success has been attributed to his conversational and approachable writing style. On the Origin of Species was so influential that within a year it had been published in German.
Japanese translation of On the Origin of Species, Shu No Kigen, published in as a five-volume, pocket-sized edition. Charles Darwin used the concept of a tree of life in the context of the theory of evolution to illustrate that all species on Earth are related and evolved from a common ancestor.

The tips of the branches show the species that are still alive today. The tree also shows those that are now extinct. Darwin explained:.
The lines on the tree show evolutionary relationships between species. For example, a recent version of the tree of life would show a line between some types of dinosaurs and the earliest birds, as scientists reason that birds evolved from a particular lineage of dinosaurs.
This means that species that are closely related are found close together stemming from the same branch. For example, humans, chimpanzees, gorillas and orangutans are all great apes, so they all belong to the same branch of the tree of life. Although Darwin's theory of evolution has been modified over time, it remains fundamental to the study of the natural world. Darwin changed not only the way we see all organisms, but also the way we see ourselves. Brimming with enthusiasm for the natural world, even Charles Darwin didn't always get it right.
An intrepid explorer and brilliant naturalist, Alfred Russel Wallace co-published the theory of evolution by natural selection with Charles Darwin.

In , he embarked on a five-year voyage around the world on the HMS Beagle , during which time his studies of various plants and an led him to formulate his theories.
In , he published his landmark book, On the Origin of Species. Darwin was born on February 12, , in the tiny merchant town of Shrewsbury, England. A child of wealth and privilege who loved to explore nature, Darwin was the second youngest of six kids. Darwin came from a long line of scientists: His father, Dr. Darwin, was a medical doctor, and his grandfather, Dr.
Erasmus Darwin, was a renowned botanist. In October , at age 16, Darwin enrolled at University of Edinburgh along with his brother Erasmus. Two years later, he became a student at Christ's College in Cambridge. His father hoped he would follow in his footsteps and become a medical doctor, but the sight of blood made Darwin queasy. His father suggested he study to become a parson instead, but Darwin was far more inclined to study natural history. He could have been charged with sedition and blasphemy for widely publishing his unpopular theory.
After returning from the voyage of the Beagle, Darwin settled down in England, married Emma Wedgwood his wealthy first cousin , raised a large family, and quietly continued his research at his newly purchased country home 16 miles south of London. In he wrote a 35 page summary of his theory about evolution. This was expanded to a page manuscript in , but it was not published and apparently was only known to a few people in British scientific circles.
Darwin busied himself over the next two decades establishing his reputation as an important naturalist by growing and studying orchids, pigeons, earthworms, and other organisms at his home. He spent 8 of these years studying and writing about barnacles that people had sent him from around the world. Emma Darwin Down House--Charles and Emma Darwin's country home where he wrote his major publications and their family lived contentedly for 40 years.
Charles Darwin It was not until he was 50 years old, in , that Darwin finally published his theory of evolution in full for his fellow scientists and for the public at large.
He did so in a page book entitled On the Origin of Species. It was very popular and controversial from the outset. The first edition came out on November 24, and sold out on that day. It went through six editions by The ideas presented in this book were expanded with examples in fifteen additional scientific books that Darwin published over the next two decades. What finally convinced Darwin that he should publish his theory in a book for the general educated public was the draft of an essay that he received in the summer of from a younger British naturalist named Alfred Wallace , who was then hard at work collecting biological specimens in Southeast Asia for sale to museums and private collectors.
Darwin was surprised to read that Wallace had come upon essentially the same explanation for evolution. Being a fair man, Darwin insisted that Wallace also get credit for the natural selection theory during debates over its validity that occurred at a meeting of the British Association for the Advancement of Science at Oxford University in We now know that Darwin deserves most of the credit.
In , one year after he returned from the voyage on the Beagle, he made detailed notes on the idea of evolution by means of natural selection. At that time, Wallace was only 14 years old. In addition, it was Darwin's book, rather than Wallace's essay, that had the most impact on the Victorian public.
Darwin not only described the process of natural selection in more detail, but he also gave numerous examples of it. It was his On the Origin of Species that convinced most scientists and other educated people in the late 19th century that life forms do change through time. This prepared the public for the acceptance of earlier human species and of a world much older than years. Both Darwin and Wallace failed to understand an important aspect of natural selection.
They realized that plant and animal populations are composed of individuals that vary from each other in physical form. They also understood that nature selects from the existing varieties those traits that are most suited to their environment. If natural selection were the only process occurring, each generation should have less variation until all members of a population are essentially identical, or clones of each other.
That does not happen. Each new generation has new variations. Darwin was aware of this fact, but he did not understand what caused the variation. The first person to begin to grasp why this happens was an obscure Central European monk named Gregor Mendel. Through plant breeding experiments carried out between and , he discovered that there is a recombination of parental traits in offspring.
Sadly, Darwin and most other 19th century biologists never knew of Mendel and his research. It was not until the beginning of the 20th century that Mendel's pioneer research into genetic inheritance was rediscovered. This was long after his death. He never received the public acclaim that was eventually showered on Darwin during his lifetime.
Charles Darwin's convincing evidence that evolution occurs was very threatening to many Christians who believed that people were created specially by God and that they have not changed biologically since that creation. The idea that there could have been prehistoric humans who were anatomically different from us was rejected for similar reasons. However, Charles Lyell's geological evidence that the earth must be much older than 6, years along with the rapidly accumulating fossil record of past evolution convinced educated lay people in the 's to think what had been unthinkable earlier.
Archaeological confirmation of the existence of prehistoric Europeans had been accumulating since the 's. However, until the late 's, it had been widely rejected or misinterpreted. His hobby was collecting ancient stone tools from deep down in the Somme River gravel deposits. Since he found these artifacts in association with the bones of extinct animals, he concluded that they must have been made at the time that those animals lived.
Boucher de Perthes tried to publish his findings in They were rejected by all important scientists and scientific journals. The prehistoric stone tools usually were dismissed as being only "lightning stones" i. However, by , his claims were beginning to be accepted by some enlightened Western European scientists. Darwin's publication of On the Origin of Species the following year convinced even more educated people that Boucher de Perthes had been right.
Darwin's popularizing the idea of evolution also made it possible for scientists to begin to accept that some of the makers of Boucher de Perthes' prehistoric tools had already been discovered and that their bones were in museums.
These bones had been found in several Western European countries during the first half of the 19th century. However, they had all been dismissed as being from odd looking modern people.
