Charles Darwin, the English scientist, is best known for his groundbreaking books “On the Origin of Species” (1859) and “The Descent of Man” (1871). His work on the theory of evolution has had a profound impact on both scientific thought and humanist ideas.
Early Life and Education
Charles Robert Darwin was born in 1809 in England. His father was a doctor, and his mother was a financier. Academically, Darwin was a disappointment to his father, who sent him to the University of Edinburgh Medical School, the best medical school in England at the time. However, Darwin found his true passion after joining the Plinian Society, a club for students interested in natural history.
Struggles in Medical School
Darwin’s stint in medical school was short-lived. He abandoned his studies after less than two years, much to his father’s dismay. Subsequently, his father enrolled him at Christ’s College, Cambridge in 1827 for a Bachelor of Arts degree, aiming for him to become a vicar.
The Voyage of the HMS Beagle
After graduating from Cambridge University, Darwin faced the prospect of becoming a vicar. However, a letter from his former teacher, John Stevens Henslow, changed his fate. Henslow recommended Darwin for an expedition aboard the H.M.S. Beagle, led by Captain Robert FitzRoy.
The Expedition
In 1831, at the age of 22, Darwin set sail on a scientific expedition. His task was to observe and collect specimens of plants, animals, rocks, and fossils. The five-year journey took him to South America, Tahiti, Australia, New Zealand, Africa, and various Atlantic and Pacific islands. Darwin meticulously documented his observations and sent back numerous specimens to England.
Fame as a Naturalist
While Darwin was away, Henslow published his observations, making Darwin famous as a naturalist by the time he returned to England. His findings on the Galápagos Islands were instrumental in developing his theory of evolution.
The Dilemma of Charles Darwin
Raised as an Anglican Christian, Darwin initially believed the Earth was around 6,000 years old and that all species were created simultaneously. However, his discoveries of fossils and extinct species suggested otherwise. He realized that the Earth had to be much older and that species evolved over time.
A Shift in Perspective
Darwin chose to follow the evidence he collected rather than adhere to the literal interpretation of the Bible. He joined scientists advocating for the separation of science and religion, famously stating:
“A scientific man ought to have no wishes, no affections, – a mere heart of stone.” – Charles Darwin
The Impact of “On the Origin of Species”
Contrary to popular belief, Darwin did not claim that humans descended directly from monkeys. His 1859 book “On the Origin of Species” focused on speciation and avoided direct mention of human evolution. However, journalists summarized his work with caricatures depicting him as half-monkey, half-human.
Public Reception
Initially, many readers did not find Darwin’s book contradictory to the Book of Genesis. By the late 19th century, the scientific consensus was that the Bible should not be read literally. Darwin’s theory, combining existing ideas and his own observations, explained the diversity of species and their origins to a broad audience.
Darwin as a Person
Despite his significant contributions to science, Darwin was a product of his time. His views on race and gender were typical of a privileged white man in 19th-century Europe. While he made some unscientific claims, he also supported the education and careers of his daughters, treating them as intellectual equals to his sons.
The Takeaway
Charles Darwin was an independent thinker whose theory of evolution revolutionized biology and challenged traditional views. Despite controversy, his work remains a cornerstone of modern science. Love him or hate him, Darwin’s contributions have undeniably shaped our understanding of life on Earth.
