Darwinism

            Charles Darwin was born on February 12, 1809 and passed away on April 19th, 1882. He was the second son of a society doctor (Robert Waring Darwin). His mother died when he was only 8 years old and was then taken care of by his sisters and father. His father ended up sending Darwin to study medicine at Edinburgh in 1825 and there he learned about the sciences studying plants and rocks. With his mentor Robert Edmond Grant, a disciple of Jean-Baptiste Lamarck, he began to collect sea slugs to try and understand the origins of more complex creatures. However, in 1828 his father switched him from Edinburgh to Cambridge for a more religious college.

Three years later he got the opportunity to travel around the world and conduct research on the HMS Beagle leaving England on December 27th, 1831. Through his voyage he discovered and noted fossils and how they mimic certain animals of modern times one of them resembling a giant sloth creature (the Megatherium). The discovery of these fossils led him to think of how and why these animals died out and for what reason some of them are still here today although with them being changed from what they used to be.

In 1834 he received word that to keep the population from rising in England the poor were sent to workhouses and kept from the opposite gender. With this information Darwin coined the term natural selection which is the process that results in the adaptation of an organism to its specific environment.  Finally, in 1835 he visited the Galapagos islands where he discovered the different types of finches but did not realize it at the time thinking they were different species entirely. The following year Darwin returned to London and in 1837 John Gould, an ornithologist, realized that the finches on the Galapagos were all the same species and further led Darwin to think more about evolution.

 It was not until two decades later that he published On the Origin of Species (1859) detailing how evolution happens and how natural selection fits in with this. The reason why he did not publish earlier was that he feared that many of his ideas would be censored at the time and he would be ostracized. In 1862 he published another book, The Various Contrivances by which British and Foreign Orchids are Fertilized by Insects, to support the previous about orchids and how they were cross pollinated and how changing one thing led to a new subspecies of the orchid in later variations.

Later Darwin was challenged on how the modern human was a descendant of “Old World monkeys”. As a result, he published the books The Descent of Man, and Selection in Relation to Sex in 1871. In The Descent of Man Darwin explained the origins of humans and how civilizations came to be. In Selection in Relation to Sex discusses how feathers on a hummingbird are used to attract female mates. This natural phenomenon was called sexual selection and Darwin related it to humans as well.

By this time Darwin had secluded himself into a laboratory to experiment and write all these books and with his second to last book The Expression of the Emotions in Man and Animals (1872) explains how that facial expressions show both humans and animals thoughts. This helps further relate and support Darwin's theory of evolution and how humans are related to their ape ancestors. Darwin ended up writing his autobiography between 1876 and 1881 with it being meant for his family more then the public. Following this in 1881 he published his last book The Formation of Vegetable Mould, Through the Action of Worms. A year later he would suffer from a seizure then a heart attack and passed away leaving all his work behind.

  1. A little more attention to the philosophical impact of evolution by natural selection, and on his late autobiographical reflections, would have been nice. It would have been good stuff to have linked to.
