Charles Darwin - Biography - Biologist, Scientist. Charles Darwin is best known for his work as a naturalist, developing a theory of evolution to explain biological change. Synopsis Naturalist Charles Darwin was born in Shrewsbury, England, on February 12, 1809. In 1831, he embarked on a five-year survey voyage around the world on the HMS Beagle. His studies of specimens around the globe led him to formulate his theory of evolution and his views on the process of natural selection. In 1859, he published On the Origin of Species. He died on April 19, 1882, in London. Early Life Naturalist Charles Robert Darwin was born on February 12, 1809, in the tiny merchant town of Shrewsbury, England. In October 1825, at age 16, Darwin enrolled at Edinburgh University along with his brother Erasmus.

Voyage on the HMS Beagle While Darwin was at Christ's College, botany professor John Stevens Henslow became his mentor. On December 27, 1831, the HMS Beagle launched its voyage around the world with Darwin in tow. Advertisement — Continue reading below Videos. Darwin Online. BBC - iWonder - Charles Darwin: Evolution and the story of our species. Charles Darwin. Charles Robert Darwin, FRS (/ˈdɑrwɪn/;[1] 12 February 1809 – 19 April 1882) was an English naturalist and geologist,[2] best known for his contributions to evolutionary theory. [I] He established that all species of life have descended over time from common ancestors,[3] and in a joint publication with Alfred Russel Wallace introduced his scientific theory that this branching pattern of evolution resulted from a process that he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding.[4] Darwin published his theory of evolution with compelling evidence in his 1859 book On the Origin of Species, overcoming scientific rejection of earlier concepts of transmutation of species.[5][6] By the 1870s the scientific community and much of the general public had accepted evolution as a fact.

Biography Early life and education Painting of seven-year-old Charles Darwin in 1816. Voyage of the Beagle Death and funeral Works. Charles Darwin. Charles Darwin, widely considered as one of the greatest and most revolutionizing scientists in history, was the British naturalist who formulated the theory of evolution. Pre-Darwin, it was thought that each species of life on earth came individually and that none had ever changed its form. He confuted this notion and demonstrated from his research that evolution is the law of nature and all living things on earth have descended from common ancestors who lived millions of years ago.

He proved that animals and plants have evolved in an orderly manner and keep on evolving even today. Advertisements Early Life: Born at Shrewsbury in 1809, Darwin was raised by his eldest sister from the tender age of eight. Darwin said goodbye to Edinburg in 1828 and sought admission in Cambridge to study Theology. Contributions and Achievements: Darwin got his big break in 1831. Throughout this voyage, Darwin collected bones of extinct animals. Later Life and Death: Gregor Mendel. Gregor Mendel is recognized as the father of genetics. He: • Founded the science of genetics. • Showed that people’s ideas about how living organisms passed traits on to their offspring were wrong. • Identified many of the rules of heredity. These rules determine how traits are passed through generations of living things. • Saw that living things pass traits to the next generation by something which remains unchanged in successive generations of an organism – we now call this ‘something’ genes. • Realized that traits could skip a generation – seemingly lost traits could appear again in another generation – he called these recessive traits. • Identified recessive and dominant traits which pass from parents to offspring. • Established, momentously, that traits pass from parents to their offspring in a mathematically predictable way.

Mendel’s work only made a big impact in 1900, 16 years after his death, and 34 years after he first published it. Advertisements You want to keep doing science? Darwin did not cheat Wallace out of his rightful place in history | John van Wyhe | Science. This year is the centenary of the death of Victorian naturalist and co-discoverer of evolution by natural selection, Alfred Russel Wallace.

So we have heard a lot about him recently, including the BBC Two series Bill Bailey's Jungle Hero, an episode of BBC Radio 4's In Our Time, two episodes of The Infinite Monkey Cage and scores of articles, talks and exhibitions. Wallace deserves more attention but much of what you will have heard about him in the last few months is factually incorrect – and amounts to a misguided campaign to reinstate the reputation of a genius who (according to his fans) has been wronged by history and robbed of his rightful fame.

Since the 1970s, the story of Wallace has become something like this: While Charles Darwin sat on his revolutionary theory for 20 years, terrified of his conservative contemporaries, Wallace boldly set out to solve the great problem of the origin of species. Swept under the carpet of history What inspired Wallace's eureka moment? Natural Selection: Charles Darwin & Alfred Russel Wallace. The genius of Darwin (left), the way in which he suddenly turned all of biology upside down in 1859 with the publication of the Origin of Species, can sometimes give the misleading impression that the theory of evolution sprang from his forehead fully formed without any precedent in scientific history.

But as earlier chapters in this history have shown, the raw material for Darwin's theory had been known for decades. Geologists and paleontologists had made a compelling case that life had been on Earth for a long time, that it had changed over that time, and that many species had become extinct. At the same time, embryologists and other naturalists studying living animals in the early 1800s had discovered, sometimes unwittingly, much of the best evidence for Darwin's theory. Pre-Darwinian ideas about evolution It was Darwin's genius both to show how all this evidence favored the evolution of species from a common ancestor and to offer a plausible mechanism by which life might evolve.
