ClassX Video Lessons Youtube Channel Biographics Alfred Russel Wallace: The Forgotten Father of Evolution
When we think of the theory of evolution, Charles Darwin is often the first name that comes to mind. However, Alfred Russel Wallace played a crucial role in developing these ideas alongside Darwin. At one time, the theory was even known as the Darwin-Wallace theory of evolution. Unfortunately, Wallace’s contributions have largely been forgotten over time, illustrating the harsh reality of “publish or perish” in the academic world.
Alfred Russel Wallace was a remarkable scientist in the 19th century, whose interests spanned across natural history, geography, anthropology, ecology, and even astrobiology. Despite lacking formal education due to financial constraints, Wallace became a self-taught scholar and a leading figure in natural history. Today, his legacy is being rediscovered, shedding light on his significant contributions to science.
Born on January 8, 1823, in Kensington Cottage near Usk, Monmouthshire, Wallace was the eighth of nine children. His family faced financial hardships, which influenced his life and career. Although his father held a law degree, he never practiced, relying instead on an inheritance and unsuccessful business ventures. Wallace’s only formal education was at Richard Hale’s Grammar School in Hertford, as he could not afford college. Despite these challenges, he became a distinguished naturalist and explorer.
In 1837, Wallace’s family faced further financial difficulties, prompting him to move to London and work as an apprentice carpenter. Later, he joined his brother William as an apprentice land surveyor, a role that allowed him to explore the British countryside and nurture his interest in the natural world.
Wallace’s passion for natural history was ignited by his friendship with Henry Walter Bates, a young entomologist he met while teaching in Leicester. Inspired by the travels of Alexander von Humboldt and Charles Darwin, Wallace realized the importance of exploring distant lands to advance his studies. In 1848, he and Bates embarked on a journey to the Amazon Rainforest, funding their expedition by selling specimens to museums and collectors.
Arriving in Brazil in 1848, Wallace and Bates initially explored the Amazon together before parting ways to cover more ground. Wallace studied insects, local cultures, and languages, and began formulating his ideas on natural selection. Unfortunately, his return to England in 1852 was marred by tragedy; his ship caught fire, destroying most of his specimens and notes. Despite this setback, Wallace’s academic papers gained recognition among British naturalists.
In 1854, Wallace embarked on a more successful expedition to the Malay Archipelago, where he collected over 120,000 specimens. His observations led to the discovery of the Wallace Line, a boundary separating Asian and Australian fauna. His experiences were chronicled in the influential book The Malay Archipelago, published in 1869.
Wallace’s most significant achievement was his work on the theory of evolution. By 1855, he believed in the evolution of species but had not identified the mechanism. In 1858, a fever-induced epiphany led him to the concept of natural selection, which he shared with Darwin. Recognizing the importance of their findings, Darwin and Wallace presented their ideas jointly at the Linnean Society of London, marking the formal introduction of the theory of evolution.
Wallace’s interests extended beyond evolution. He participated in the Bedford Level Experiment to debunk flat-earth theories, although this led to a prolonged legal battle. He was also an early environmentalist, warning about human impacts on the climate, and explored the possibility of extraterrestrial life.
Despite his scientific achievements, Wallace held controversial beliefs, such as spiritualism and opposition to mandatory smallpox vaccinations, which strained some professional relationships. Nevertheless, he remained active, authoring nearly two dozen books and over 500 scientific papers.
Alfred Russel Wallace passed away on November 7, 1913, at the age of 90. Although he was not buried in Westminster Abbey, a medallion honoring him was placed next to Darwin’s, acknowledging his invaluable contributions to science. Today, Wallace is remembered as a pioneering thinker who helped shape our understanding of the natural world.

**Alfred Russel Wallace – The Forgotten Father of Evolution**
The name “Alfred Russel Wallace” may not be widely recognized, but it should be. If you know about Charles Darwin, you should also be aware of Alfred Wallace, as both contributed significantly to the theory of evolution. At one point, Darwin’s theory was referred to as the Darwin-Wallace theory of evolution. However, Wallace’s contributions gradually faded from public consciousness, exemplifying the concept of “publish or perish.”
Alfred Wallace was one of the most notable scientists of the 19th century. He was more than just a naturalist; he also studied geography, anthropology, ecology, and even astrobiology. Remarkably, he was self-taught, driven by necessity rather than desire, as he came from a modest background and could not afford a formal education. Today, Wallace is receiving some of the recognition he deserves as we explore the life and career of this luminary of natural history.
**Early Years**
Alfred Russel Wallace was born on January 8, 1823, at Kensington Cottage near Usk, Monmouthshire, which is now in Wales but was considered part of a gray area between Wales and England at the time. This distinction may seem trivial, but it has led to debates about Wallace’s identity; he referred to himself as an Englishman. He was the eighth of nine children of Thomas Vere Wallace and Mary Anne Greenell. His mother was English, while his father was Scottish and claimed descent from the famous William Wallace, though this was never conclusively proven.
Wallace’s family faced financial difficulties that affected him throughout his life. Before his birth, they lived in London but moved to Monmouthshire to reduce living costs. Thomas Wallace had a law degree but never practiced law, relying instead on an inheritance and various unsuccessful business ventures. When Wallace was five, the family relocated to Hertford, where he attended Richard Hale’s Grammar School, receiving the only formal education of his life. He never attended college due to financial constraints but became a distinguished naturalist and explorer.
In 1837, when Wallace was a teenager, his family’s financial situation worsened after his father lost everything in a swindle. Unable to afford school, Wallace moved to London to live with his older brother, John, who found him an apprenticeship as a carpenter. After a few months, he moved in with another brother, William, who took him on as an apprentice land surveyor. The two worked together for six years until business slowed, prompting Wallace to seek new employment.
In 1844, he secured a teaching position at the Collegiate School in Leicester, where he taught surveying and mapmaking. This was a pivotal moment for Wallace, as he met Henry Walter Bates, a young entomologist who sparked Wallace’s interest in the study of insects.
Tragedy struck in 1845 when Wallace’s brother William died unexpectedly. He left his teaching position to take control of William’s surveying business in Neath. During this time, Wallace’s interest in the natural world grew, and he began collecting insects. He expressed a desire to study one family of insects thoroughly “with a view to the theory of the origin of species.” His surveying work allowed him to explore the British countryside, although he disliked the bureaucratic responsibilities that came with it.
Inspired by the travels of naturalists like Alexander von Humboldt and Charles Darwin, Wallace realized he needed to travel to distant lands to further his studies. With Bates as his companion, they planned to fund their trip by selling specimens to museums and collectors. In April 1848, they set off from Liverpool to the Amazon Rainforest.
**A Trip into the Amazon**
The explorers arrived in Belém, Brazil, in late May and ventured into the rainforest. After a few months, Wallace and Bates decided to part ways, possibly to cover more ground. While Bates spent over a decade in the Amazon, Wallace diversified his interests, studying not only insects but also the local people, languages, and cultures. He charted the Rio Negro, one of the Amazon’s largest tributaries, and began developing his theory of natural selection.
In 1852, due to poor health, Wallace decided to return to England. However, he faced a series of unfortunate events. He learned that his younger brother Herbert had died from yellow fever while exploring the Amazon. Additionally, all the specimens he had sent back to England were delayed at a dock in Manaus. While returning home, the ship he was on caught fire and sank, resulting in the loss of most of his specimens and notes, save for a couple of notebooks he managed to save.
Back in London, Wallace had to reassess his next steps. Although he lost much of his collection, it was partially insured, providing him some financial relief. Despite the setbacks, he wrote several well-received academic papers that helped establish him among British naturalists.
In 1854, eager to continue exploring, Wallace set off for the Malay Archipelago, known then as the East Indies.
**The Malay Expedition**
This expedition proved far more fruitful for Wallace, who spent the next eight years collecting over 120,000 specimens and employing numerous assistants to help in his research. Among them was a young boy named Ali, who began as a cook and cleaner but eventually became Wallace’s most trusted companion, collecting and preparing thousands of specimens.
During his time in the East Indies, Wallace discovered and described many new species. He noted a significant change in wildlife between the islands of Bali and Lombok, leading to the identification of the Wallace Line, a natural boundary between Asian and Australian fauna. He chronicled his expedition in the book *The Malay Archipelago*, published in 1869, which became one of the most significant science books of the 19th century.
**The Theory of Evolution**
Wallace’s most notable achievement was his work on the theory of evolution. By 1855, he was convinced that living organisms evolve over time but had not yet identified the mechanism behind this process. In 1858, after suffering from a fever, he experienced a moment of clarity and realized that species evolve to adapt to their environments. He quickly wrote down his theory and sent it to Charles Darwin for review.
It’s important to note that there was no competition between the two; Wallace respected Darwin’s work and sought his input because he knew Darwin was studying similar concepts. Darwin, aware of potential controversy, consulted colleagues and decided that both should present their findings together. On July 1, 1858, the Linnean Society of London announced the joint paper on natural selection, marking the first formal presentation of the Darwin-Wallace theory of evolution.
Darwin later condensed his findings into the influential book *On the Origin of Species*, which became synonymous with the theory of evolution, overshadowing Wallace’s contributions. Despite this, Wallace continued his research in the East Indies for four more years before returning to England, where he began giving presentations on evolution and befriended Darwin and other scientists.
**The Bedford Level Experiment**
In addition to his explorations and evolutionary work, Wallace was involved in the Bedford Level Experiment, which he later regarded as “the most regrettable incident in [his] life.” This began in 1838 when a flat-earther named Samuel Rowbotham claimed to have proven the Earth was flat through observations along the Old Bedford River. Wallace, seeking to debunk this claim, engaged in a lengthy legal battle with Rowbotham’s supporter, John Hampden, which lasted 15 years and caused Wallace significant distress.
**Other Interests**
Wallace was known for his diverse interests, earning the title “Grand Old Man of Science.” He was an early environmentalist, warning about the negative impacts of human activities on the climate. In his later years, he explored the possibility of extraterrestrial life, publishing works on planetary habitability.
Despite his scientific achievements, Wallace held controversial beliefs, including a strong interest in spiritualism and opposition to mandatory vaccinations for smallpox, which strained his relationships with some colleagues. Nevertheless, he remained active throughout his life, writing nearly two dozen books and over 500 scientific papers.
Wallace passed away on November 7, 1913, at the age of 90. Although there were calls for him to be buried at Westminster Abbey, he was laid to rest in Broadstone Cemetery, in accordance with his wishes, with a medallion placed at Westminster next to Charles Darwin.
