Charles Darwin was a renowned British naturalist and biologist best known for his theory of evolution through natural selection. His theory that all life evolved from a common ancestor is now a cornerstone of modern science, making Darwin one of the most influential individuals in history. It is difficult to overstate the monumental influence his work has had on our scientific understanding of the world.

This article discusses Charles Darwin's life and work, including his famous theory of natural selection as well as some of his lesser-known research on human emotion.

Charles Darwin was born in Shrewsbury, England, on February 12, 1809. His father was a wealthy doctor, and his grandfather on his mother's side was the noted potter Josiah Wedgwood. After his mother’s death when he was eight, Darwin began attending boarding school with his older brother. 

Darwin originally began his studies at the University of Edinburgh Medical School, but later developed an interest in ministry and botany, eventually receiving his degree from Cambridge in 1831.

His famed voyage to the Galapagos Islands led to the observations that served as the basis for Darwin's groundbreaking theory of natural selection.

In 1839, Darwin married his cousin Emma Wedgwood. They had 10 children together, with seven surviving to adulthood. In 1859, he published his observations and ideas in his book "On the Origin of Species By Means of Natural Selection."

Darwin's ideas were heavily debated in his own time and continue to spark controversy today. In contrast to this, Darwin himself lived a secluded life at his home in England, where he continued to work as a highly regarded scientist.

Darwin died on April 19, 1882, and is buried at Westminster Abbey in London, England.

Darwin's Illness

For much of his adult life, Darwin had an undiagnosed chronic illness that limited his activities. Symptoms included physical complaints such as stomach pain and dizziness, as well as signs of panic attacks such as shortness of breath and heart palpitations.

One theory suggests that he may have had panic disorder with agoraphobia . This diagnosis would also explain his secluded lifestyle, difficulty with public speaking, and struggles when meeting with colleagues.

Other proposed diagnoses include mercury poisoning, allergies, Crohn's disease, and irritable bowel syndrome. However, many researchers now believe that he had an adult-onset mitochondrial disorder.

What Was Charles Darwin Most Famous For?

Charles Darwin is most famous for his theory of evolution through the process of natural selection. Since introducing his ideas in “On the Origin of the Species,” his work has revolutionized the scientific understanding of how species evolve over time. This helped lay the foundation for modern biological sciences .

His Studies on the Galapagos Islands

During a voyage on a ship called the HMS Beagle, Darwin traveled to the Galapagos Islands, a journey that had a profound influence on his thinking and ideas. During this trip, he noticed interesting variations in the different species of finches that lived on the islands.

The beaks of these birds appeared to vary depending on the native food sources where the birds lived. Darwin hypothesized that the variations he observed resulted from natural selection that favored birds with beaks suited to the local food sources.  

There are 14 species of finches found on the Galapagos Islands, which are now collectively referred to as "Darwin's finches."

In “On the Origin of the Species,” Darwin suggested that all species on Earth, including humans, evolved from common ancestors. The diversity found in all species, he explained, results from changes that occur gradually over very long periods of time, a process he referred to as “descent with modification.” This happens through natural selection, where certain traits that benefit an organism's survival are more likely to be passed down. 

Because these organisms are more likely to survive and reproduce, those beneficial traits are more likely to be handed down. This leads to the adaptation and evolution of species.

Charles Darwin's concept of evolution through natural selection suggested that species change slowly over time as a response to their environment. This theory changed our scientific understanding of the diversity of life on Earth and laid the groundwork for the development of modern biology.

How Does Natural Selection Work?

According to Darwin, the individuals within a population possess variations, some of which are better suited to the environment in which they live. As a result, those with these adaptations are more likely to survive, reproduce, and thus pass these advantageous characteristics down to their offspring.

Over time, this process gradually leads the adaptive traits to become more prominent and can eventually lead to the emergence of new species.

The Five Principles of Natural Selection

The five principles of natural selection described by Charles Darwin can be remembered using the acronym VISTA, standing for variation, inheritance, selection, time, and adaptation.

• Variation : In all populations of any species, there are individual variations in different traits. The species' members can vary in appearance, size, abilities, immunity, and numerous other characteristics. Many of these variations result from genetic inheritance but can also occur due to random mutations.
• Inheritance : The various traits organisms possess can be inherited through genetic inheritance. In other words, when members of a species reproduce, their offspring are more likely to also possess those same traits.
• Selection : Environmental resources are limited, so organisms with advantageous characteristics that make it easier for them to survive are more likely to thrive in their environment and reproduce. This increased chance of reproduction means that their children are more likely to have the same traits that helped their ancestors survive.
• Time : As time passes, each generation continues to produce more offspring with advantageous characteristics. With the passage of time, the beneficial traits continue to accumulate, resulting in significant changes in the characteristics of the entire population.
• Adaptation : Such traits eventually become more common in the population, making the entire species better suited to survive in their environment.

What Does ‘Survival of the Fittest’ Mean?

An important part of natural selection is the idea of ‘survival of the fittest.’ The phrase was first introduced in 1854 by Herbert Spencer in his book "The Principles of Biology."

The idea suggests that when it comes to each organism's struggle to survive and reproduce, those with traits that make them the best suited to their environment are the most likely to survive and pass down their genes to the next generation.

In this context, "fitness" refers to an organism's ability to survive in its environment and reproduce. It is the traits that help the individual survive that are considered most advantageous. 

Fitness does not refer to physical strength. Instead, it means the individual has traits that make them better suited for life in a specific environment. For example, an organism with coloring that camouflages it from predators would be considered a better fit, from an evolutionary perspective, than coloring that makes it more susceptible to becoming prey.

Fitness can refer to a wide variety of characteristics. This might include physical attributes such as camouflage, speed, strength, or agility. It might also refer to behavioral adaptations that confer a greater chance of survival. Migration, hibernation, and courtship behaviors are a few examples of behavioral adaptations influenced by evolution.

Controversies Surrounding Darwin’s Theory of Evolution

Darwin's theory was considered shocking and controversial after its introduction. While the theory is accepted by nearly all scientists today, Darwin's ideas are still disputed or rejected by some people.

Darwin and his work have remained controversial in the more than 140 years since his death. One survey found that a third of U.S. adults reject the idea that humans evolved through natural selection, views that correspond with rates of religious belief.

One critic during Darwin's time was the English comparative anatomist and paleontologist Richard Owen. While Owen agreed that evolution occurred, he was a vocal critic of Darwin's idea of natural selection. Instead, he proposed the existence of predetermined "archetypes" that guide the evolutionary changes that species experience. 

During Darwin's time, some critics suggested that the lack of transitional fossils (demonstrating the gradual progression of a species over time) was evidence that Darwin’s evolutionary theory was wrong. In the subsequent years, however, many of these so-called "missing links" have been added to the fossil record, providing paleontological support for these evolutionary transitions.

Other critics focus on their belief that all life results from divine creation. However, it is important to note that Darwin's theory of evolution does not focus on how life originated. Instead, Darwin's theory of natural selection explains how life evolved over time and how this explains the diversity of life on Earth.

While there have been debates and criticisms from various sources, it is important to note that Darwin was highly regarded in his own time. Support from the scientific community continued to build over the years, and more evidence supporting Darwin's theory accumulated from various fields.

Charles Darwin’s Research on Human Emotions

While Darwin is best known for his theory of evolution, he also studied and wrote about a wide range of topics, from plants to sea life. Beyond his work as a naturalist, he also conducted one lesser-known experiment on the study of human emotions , making him one of the earliest experimental psychology researchers. 

In archival research looking at Darwin's letters and other writings, researchers found references to a small experiment that Darwin had conducted at home. Darwin had corresponded with the French physician Guillaume Duchenne de Boulogne, who had used electrical impulses to stimulate facial muscles into specific expressions, which were then recorded on photographic plates. Using this method, Duchenne suggested that the human face is capable of expressing at least 60 distinct emotions.

Darwin disagreed. Using Duchenne's plates, Darwin devised his own experiment, a single-blind study in which he randomized the order of the plates and then presented them to over 20 participants (i.e., Darwin's guests). He then asked his guests to identify the emotions represented in the photographic slides. 

In studying Darwin's notes, researchers discovered that the participants agreed when it came to the basic emotions , such as happiness , surprise, and fear. For more ambiguous photographs, responses were much more mixed.

In Darwin's view, only those emotions that were readily identifiable and agreed upon by observers represented universal emotions.

Darwin's observations and conclusions in this and other studies he conducted helped inform his 1872 book "The Expression of the Emotions in Man and Animals." In this book, Darwin emphasized the importance of emotional expression in both humans and animals, suggesting that:

• Some emotional expressions are universal
• Some emotions have a biological, evolutionary basis
• These universal expressions evolved through natural selection because they aid in survival, reproduction, and communication
• Humans and animals display similar emotions, suggesting they have a common evolutionary origin

Darwin's work offered insights into the importance of emotions, their evolutionary roots, and their universality across cultures and species . His observations also helped lay the groundwork for future research on the psychology of human emotions.

However, Darwin's ideas about emotion were eclipsed by his more famous theory of natural selection. It wasn't until the 1960s that psychologist Paul Ekman returned to Darwin's findings and, using methods similar to those originally pioneered by Darwin, found additional evidence for the existence of basic, universal human emotions.

The Darwin Correspondence Project allows viewers to see the original photographic plates Duchenne and Darwin used this in their experiments. You can also give your own response and see how your interpretation compares to those of Darwin's guests.

What Were Charles Darwin’s Views on Women?

While Darwin revolutionized the field of science, his views on women were far from progressive. His attitudes reflected the prevailing sexist, misogynistic ideas of his time. In his published writings, he echoed the societal and cultural beliefs that women were inferior to men, viewing them as less intelligent.

In his book "The Descent of Man," Darwin wrote, "Woman seems to differ from man in her mental disposition, chiefly in her greater tenderness and less selfishness."

Darwin suggested that the purported superiority of men stemmed from sexual selection, a mode of natural selection in which men compete for mates, leading to the evolution of characteristics that improve their reproductive fitness, including intelligence, physical strength, and competitiveness.

He believed that women's roles were primarily as domestic caretakers and nurturers, which, in his view, did not require strong intellectual capabilities.

There is evidence that Darwin's ideas changed somewhat over time, often influenced by the women in his life, including his wife, daughters, and women intellectuals. While he could not be regarded as a feminist thinker, research on his private correspondence suggests that his views on women were more complex than what appears in his published writing.

Who Did Charles Darwin Influence?

In addition to his profound influence on the biological sciences, Darwin inspired a number of other scientists and researchers in their own work.

Some of these thinkers included:

• Alfred Russel Wallace : A contemporary of Darwin, Wallace was an English naturalist and explorer who independently introduced the idea of evolution through natural selection. His own ideas were published in 1858 along with some of Darwin's earlier writings, prompting Darwin to publish "On the Origin of the Species" the next year.
• William James : The founder of the functionalist school of thought in psychology was heavily influenced by the work of Charles Darwin. This school of thought suggests that the functions of the mind exist because they serve a purpose in survival and adaptation. This idea has its roots in Darwin's theory of natural selection. James was also heavily influenced by Darwin's writings on the topic of emotions. According to the James-Lange theory of emotions , emotions stems from the physiological reactions people experience in response to environmental stimuli.
• Ronald A. Fisher : A British mathematician and biologist, Fisher is considered a founder of modern statistical science. He also played an important role in what is known as modern synthesis, which involved integrating Darwin's natural selection with Mendelian genetics in order to explain how genetic variations within a group can be affected by natural selection.

How Does Charles Darwin’s Work Affect Modern Science Today?

It is difficult to overstate the enormous impact of Darwin's work on modern science. Some of the ways that science continues to be impacted by Darwin's theory of evolution include:

• Evolutionary sciences : The theory of evolution plays an essential role in biology as well as other fields that explain how life has adapted and changed over time, including genetics and evolutionary psychology .
• Medicine : Researchers continue to use their understanding of evolutionary science to study how diseases originate, spread, and mutate.
• Scientific education : While Darwin's ideas remain controversial for some, his work has helped advance scientific literacy and understanding among the general public.

Charles Darwin

(1809-1882)

Who Was Charles Darwin?

Charles Robert Darwin was a British naturalist and biologist known for his theory of evolution and his understanding of the process of natural selection. In 1831, 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 1859, he published his landmark book, On the Origin of Species .

Darwin was born on February 12, 1809, 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. R.W. Darwin, was a medical doctor, and his grandfather, Dr. Erasmus Darwin, was a renowned botanist. Darwin’s mother, Susanna, died when he was only eight years old.

In October 1825, 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.

While Darwin was at Christ's College, botany professor John Stevens Henslow became his mentor. After Darwin graduated Christ's College with a bachelor of arts degree in 1831, Henslow recommended him for a naturalist’s position aboard the HMS Beagle .

The ship, commanded by Captain Robert FitzRoy, was to take a five-year survey trip around the world. The voyage would prove the opportunity of a lifetime for the budding young naturalist.

On December 27, 1831, the HMS Beagle launched its voyage around the world with Darwin aboard. Over the course of the trip, Darwin collected a variety of natural specimens, including birds, plants and fossils.

Darwin in the Galapagos

Through hands-on research and experimentation, he had the unique opportunity to closely observe principles of botany, geology and zoology. The Pacific Islands and Galapagos Archipelago were of particular interest to Darwin, as was South America.

Upon his return to England in 1836, Darwin began to write up his findings in the Journal of Researches , published as part of Captain FitzRoy's larger narrative and later edited into the Zoology of the Voyage of the Beagle .

The trip had a monumental effect on Darwin’s view of natural history. He began to develop a revolutionary theory about the origin of living beings that ran contrary to the popular view of other naturalists at the time.

Theory of Evolution

Darwin’s theory of evolution declared that species survived through a process called "natural selection," where those that successfully adapted or evolved to meet the changing requirements of their natural habitat thrived and reproduced, while those species that failed to evolve and reproduce died off.

Through his observations and studies of birds, plants and fossils, Darwin noticed similarities among species all over the globe, along with variations based on specific locations, leading him to believe that the species we know today had gradually evolved from common ancestors.

Darwin’s theory of evolution and the process of natural selection later became known simply as “Darwinism.”

At the time, other naturalists believed that all species either came into being at the start of the world or were created over the course of natural history. In either case, they believed species remained much the same throughout time.

'Origin of Species'

In 1858, after years of scientific investigation, Darwin publicly introduced his revolutionary theory of evolution in a letter read at a meeting of the Linnean Society . On November 24, 1859, he published a detailed explanation of his theory in his best-known work, On the Origin of Species by Means of Natural Selection.

In the next century, DNA studies provided scientific evidence for Darwin’s theory of evolution. However, controversy surrounding its conflict with Creationism — the religious view that all of nature was born of God — is still found among some people today.

Social Darwinism

Social Darwinism is a collection of ideas that emerged in the late 1800s that adopted Darwin’s theory of evolution to explain social and economic issues.

Darwin himself rarely commented on any connections between his theories and human society. But while attempting to explain his ideas to the public, Darwin borrowed widely understood concepts, such as “survival of the fittest” from sociologist Herbert Spencer.

Over time, as the Industrial Revolution and laissez faire capitalism swept across the world, social Darwinism has been used as a justification for imperialism, labor abuses, poverty, racism, eugenics and social inequality.

Following a lifetime of devout research, Charles Darwin died at his family home, Down House, in London, on April 19, 1882. He was buried at Westminster Abbey .

More than a century later, Yale ornithologist Richard Brum sought to revive Darwin's lesser-known theory on sexual selection in The Evolution of Beauty .

While Darwin's original attempts to cite female aesthetic mating choices as a driving force of evolution was criticized, Brum delivered an effective argument via his expertise in birds, earning selection to The New York Times ' list of 10 best books of 2017.

Charles Darwin: History’s most famous biologist

Charles Robert Darwin (1809-1882) transformed the way we understand the natural world with ideas that, in his day, were nothing short of revolutionary.

He and his fellow pioneers in the field of biology gave us insight into the fantastic diversity of life on Earth and its origins, including our own as a species.

Charles Darwin is celebrated as one of the greatest British scientists who ever lived, but in his time his radical theories brought him into conflict with members of the Church of England.

Young Charles Darwin

Born in 1809 in Shrewsbury, Shropshire, Darwin was fascinated by the natural world from a young age. Growing up he was an avid reader of nature books and devoted his spare time to exploring the fields and woodlands around his home, collecting plants and insects.

In 1825 Darwin enrolled in medical school at the University of Edinburgh, where he witnessed surgery on a child. Surgeries at the time would have been carried out without the use of anaesthetic or antiseptics, and fatalities were common.

Watching this procedure left Darwin so traumatised that he gave up his studies without completing the course.

During his time in Edinburgh, Darwin also paid for lessons in taxidermy from John Edmonstone , a former enslaved man from Guyana. The skills Edmonstone taught Darwin became crucial just a few years further into his career.

After his time in Scotland, Darwin went to Cambridge University to study theology.

The voyage of HMS Beagle

In no rush to take holy orders, in 1831 Darwin accepted an offer to embark on a five-year voyage aboard HMS Beagle. 

Drawing of H.M.S. Beagle from A Naturalist’s Voyage Round the World by Charles Darwin.

He was recommended by one of his Cambridge professors for the role as naturalist and companion to the ship’s captain, Robert FitzRoy.

The journey would change both his life and the trajectory of Western scientific thinking.

Darwin explored remote regions and marvelled at a world so different from the one he knew. He encountered birds with bright blue feet, sharks with T-shaped heads and giant tortoises.

On his travels Darwin collected plants, animals and fossils, and took copious field notes. These collections and records provided the evidence he needed to develop his remarkable theory.

The shells in this specimen drawer were collected by Charles Darwin during the voyage of the HMS Beagle.

Darwin returned to England in 1836. A highly methodical scholar, constantly collecting and observing, he spent many years comparing and analysing specimens before finally declaring that evolution occurs by a process of natural selection.

What is the theory of natural selection?

To this day the theory of evolution by natural selection is accepted by the scientific community as the best evidence-based explanation for the diversity and complexity of life on Earth.

The theory proposes that the ‘fittest’ individual organisms - those with the characteristics best suited to their environment - are more likely to survive and reproduce. They pass on these desirable characteristics to their offspring.

Gradually these features may become more common in a population, so species change over time. If the changes are great enough, they could produce a new species altogether .

On his travels Darwin had collected finches from many of the Galápagos Islands - off the coast of Ecuador - which helped him to formulate his idea.

Some of these finches had stout beaks for eating seeds, others were insect specialists. But Darwin realised that they were all descendants of a single ancestor. As they dispersed to different islands, the birds had adapted to eat the various foods available. Natural selection had produced 13 different species of finch.

Darwin’s pigeons

From his travels on HMS Beagle, Darwin suspected that the environment might naturally manipulate species, causing them to change over time - but he couldn’t find a means to explore this effectively in the wild. 

Experimenting with artificial selection in pigeons gave him a way to study how far a species could change.

By artificially selecting features - crossing birds with particular characteristics to generate different offspring - he gathered valuable evidence for evolution by natural selection.

To illustrate his theory, Darwin bred the birds to have exaggerated features.

The similarity between artificial selection and natural selection is at the heart of his explanation of evolution in his revolutionary book On the Origin of Species. 

After completing his experiments, he gave all 120 of his pigeon specimens to the Museum. They are currently part of our bird collections  kept at Tring , Hertfordshire.

A shared discovery

Darwin knew his radical ideas would be met with stiff opposition. Even after 20 years of research, he worried about how his theory of evolution would be received as it challenged widely held religious beliefs of the time. 

He delayed publishing on the topic for a great number of years while he assembled a mountain of evidence. When he learned that the young naturalist Alfred Russel Wallace had developed similar ideas, Darwin volunteered to send Wallace's ideas to a journal for immediate publication.

On advice from friends, the two scientists organised a joint announcement. Their theory of evolution by natural selection was presented at the Linnean Society in London.

Both had studied the natural world extensively and made a number of observations that were critical to the development of the theory.

The following year, Darwin published the contentious but now-celebrated book, ‘On the Origin of Species’.

On the Origin of Species

Published in 1859, On the Origin of Species provoked outrage from some members of the Church of England as it implicitly contradicted the belief in divine creation.

Despite accusations of blasphemy, the book quickly became a bestseller.

Foreign language first editions of some works by Charles Darwin.

The Descent of Man, and Selection in Relation to Sex - which Darwin published in 1871 - fuelled even greater debate as it suggested that humans descended from apes.

The Bishop of Oxford famously asked Thomas Huxley, one of Darwin’s most enthusiastic supporters, whether it was through his grandfather or grandmother that he claimed descent from a monkey.

Despite the attacks, Darwin’s conviction in the scientific explanation that best fit the available evidence remained unshaken.

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. In Darwin's lifetime, his book was translated into German, Danish, Dutch, French, Hungarian, Italian, Polish, Russian, Serbian, Spanish and Swedish. 

Our Library has 478 editions of On the Origin of Species in 38 languages and in Braille.

Japanese translation of On the Origin of Species, Shu No Kigen, published in 1914 as a five-volume, pocket-sized edition.

Darwin and the tree of life

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:

‘From the first growth of the tree, many a limb and branch has decayed and dropped off; and these fallen branches of various sizes may represent those whole orders, families, and genera which have now no living representatives, and which are known to us only in a fossil state.’

Orders, families and genera are all groups that can be used to classify organisms.

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.

Darwin’s legacy

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.

Charles Darwin was born in 1809 in Shrewsbury, England. His father, a doctor, had high hopes that his son would earn a medical degree at Edinburgh University in Scotland, where he enrolled at the age of sixteen. It turned out that Darwin was more interested in natural history than medicine—it was said that the sight of blood made him sick to his stomach. While he continued his studies in theology at Cambridge, it was his focus on natural history that became his passion.

In 1831, Darwin embarked on a voyage aboard a ship of the British Royal Navy, the HMS Beagle, employed as a naturalist . The main purpose of the trip was to survey the coastline of South America and chart its harbors to make better maps of the region. The work that Darwin did was just an added bonus.

Darwin spent much of the trip on land collecting samples of plants, animals, rocks, and fossils . He explored regions in Brazil, Argentina, Chile, and remote islands such as the Galápagos. He packed all of his specimens into crates and sent them back to England aboard other vessels.

Upon his return to England in 1836, Darwin’s work continued. Studies of his samples and notes from the trip led to groundbreaking scientific discoveries. Fossils he collected were shared with paleontologists and geologists, leading to advances in the understanding of the processes that shape the Earth’s surface. Darwin’s analysis of the plants and animals he gathered led him to question how species form and change over time. This work convinced him of the insight that he is most famous for— natural selection . The theory of natural selection says that individuals of a species are more likely to survive in their environment and pass on their genes to the next generation when they inherit traits from their parents that are best suited for that specific environment. In this way, such traits become more widespread in the species and can lead eventually to the development of a new species .

In 1859, Darwin published his thoughts about evolution and natural selection in On the Origin of Species . It was as popular as it was controversial. The book convinced many people that species change over time—a lot of time—suggesting that the planet was much older than what was commonly believed at the time: six thousand years.

Charles Darwin died in 1882 at the age of seventy-three. He is buried in Westminster Abbey in London, England.
