Early Life

Charles Darwin was born on February 12, 1809, in Shrewsbury, England. His father was a medical doctor, and his mother was the daughter of the famous potter Josiah Wedgwood. Darwin’s mother died when he was 8, and he was essentially raised by his older sisters. He was not a brilliant student as a child, but he went on to study at the University of Edinburgh Medical School in Scotland, at first intending to become a doctor.

Darwin took a strong dislike to medical education and eventually studied at Cambridge. He planned to become an Anglican minister before becoming intensely interested in botany. He received a degree in 1831.

Voyage of the Beagle

On the recommendation of a college professor, Darwin was accepted to travel on the second voyage of the H.M.S. Beagle. The ship was embarking on a scientific expedition to South America and islands of the South Pacific, leaving in late December 1831. The Beagle returned to England nearly five years later, in October 1836.

Darwin's position on the ship was peculiar. A former captain of the vessel had become despondent during a long scientific voyage because, it was assumed, he had no intelligent person to converse with while at sea. The British Admiralty thought sending an intelligent young gentleman along on a voyage would serve a combined purpose: he could study and make records of discoveries while also providing intelligent companionship for the captain. Darwin was chosen to go aboard.

Darwin spent more than 500 days at sea and about 1,200 days on land during the trip. He studied plants, animals, fossils, and geological formations and wrote his observations in a series of notebooks. During long periods at sea, he organized his notes.

In the Galapagos

The Beagle spent about five weeks in the Galapagos Islands. During that time, Darwin made a series of observations that had a significant impact on his new theories about natural selection. He was particularly intrigued by his discovery of major differences between species on different islands. He wrote:

The distribution of tenants of this archipelago would not be nearly so wonderful if, for instance, one island has a mocking-thrush and a second island some other quite distinct species... But it is the circumstance that several of the islands possess their own species of tortoise, mocking-thrush, finches, and numerous plants, these species having the same general habits, occupying analogous situations, and obviously filling the same place in the natural economy of this archipelago, that strikes me with wonder.

Darwin visited four of the Galapagos Islands, including Chatham Island (now San Cristobal), Charles (now Floreana), Albemarle, and James (now Santiago). He spent much of his time sketching, collecting specimens, and observing animals and their behavior. His discoveries would change the scientific world and rock the foundations of Western religion.

Early Writings

Three years after returning to England, Darwin published the "Journal of Researches," an account of his observations during the expedition aboard the Beagle. The book was an entertaining account of Darwin's scientific travels and was popular enough to be published in successive editions.

Darwin also edited five volumes titled "Zoology of the Voyage of the Beagle," which contained contributions by other scientists. Darwin himself wrote sections dealing with the distribution of animal species and geological notes on fossils he had seen.

Development of Darwin's Thinking

The voyage on the Beagle was, of course, a highly significant event in Darwin’s life, but his observations on the expedition were hardly the only influence on the development of his theory of natural selection. He was also greatly influenced by what he was reading.

In 1838 Darwin read an "Essay on the Principle of Population," which the British philosopher Thomas Malthus had written 40 years earlier. The ideas of Malthus helped Darwin refine his own notion of “survival of the fittest.”

Darwin's Ideas of Natural Selection

Malthus had been writing about overpopulation and discussed how some members of society were able to survive difficult living conditions. After reading Malthus, Darwin kept collecting scientific samples and data, eventually spending 20 years refining his own thoughts on natural selection.

Darwin married Emma Wedgwood in 1839. Illness prompted him to move from London to the country in 1842. His scientific studies continued, and he spent years studying various lifeforms to better understand their evolutionary processes.

Publication of His Masterpiece

Darwin’s reputation as a naturalist and geologist had grown throughout the 1840s and 1850s, yet he had not revealed his ideas about natural selection widely. Friends urged him to publish them in the late 1850s; it was the publication of an essay by Alfred Russell Wallace expressing similar thoughts that encouraged Darwin to write a book setting out his own ideas.

In July 1858, Darwin and Wallace appeared together at the Linnean Society of London. And in November 1859, Darwin published the book that secured his place in history: "On the Origin of Species By Means of Natural Selection."

Death

"On the Origin of Species" was published in several editions, with Darwin periodically editing and updating material in the book. And while society debated Darwin's work, he lived a quiet life in the English countryside, content to conduct botanical experiments. He was highly respected, regarded as a grand old man of science. He died on April 19, 1882, and was honored by being buried at Westminster Abbey in London.

Legacy

Charles Darwin was not the first person to propose that plants and animals adapt to circumstances and evolve over eons of time. But Darwin's book put forth his hypothesis in an accessible format and led to controversy. Darwin's theories had an almost immediate impact on religion, science, and society at large.
