Many who know a bit about the history of science know what Charles Darwin is known for. But who was he really, what was his original profession, and what was his childhood like? Here I will tell you about his life and the theories he came up with. Charles Darwin was one of those who tried to prove the theory of evolution. Many people think he was the one behind the theory, but Darwin was actually not the first to come up with the theory of evolution.
Aristotle, who lived in the 4th century BC, was the first to analyze the similarities and differences between humans and animals. He systematized and classified animals based on their anatomical structure. He once said that humans are the animal we know best. It was Jean Baptiste Lamarck (1744-1829) who first launched the theory of evolution in 1801, and believed that the development of organisms is mainly due to the environment and that these could be inherited. Charles' grandfather, Erasmus Darwin, actually tried in 1794 to prove his theory that animal species are changeable. It was not Charles Darwin that we associate with the "creator of the theory of evolution". Charles Darwin was only a developer of the theory.
Charles Robert Darwin was born on February 9, 1809 in Shrewsbury, England. It wasn't long before he became interested in biology, and collecting animals, plants, shells, rocks, and other things from nature. One day he found two rare beetles. He took one beetle in each hand. Then a third beetle appeared, also rare. He put it in his mouth so as not to lose it. The beetle reacted by squirting out a nasty juice, so Darwin had to spit it out. This shows how interested and committed he was to his hobby.
Darwin started school in 1817. Darwin's father wanted Charles to study medicine. Charles studied medicine at the University of Edinburgh from 1825. In 1827 he did not want to study there anymore, after an episode he witnessed. They had gone into an operating room to watch doctors amputate a man's foot. And at that time they did not have any form of anesthesia or sleeping pills. Darwin did not think it was a profession that suited him.
Darwin remained interested in biology after 1827, and he wanted to study biology. His father wanted him to study botany and religion. Charles Darwin studied botany and biology at Christ College until 1831. He joined several geological expeditions, including with Adam Sedgwick to Wales in the summer of 1831. Sedgwick was Darwin's geology teacher at Christ College, and at the same time he supported the catastrophe theory of the origin of the Earth.
“HMS Beagle” made the first surveying voyage to South America in 1828-1830. FrizRoy had taken 4 natives from South America with him. His idea was to send them back as Christian missionaries. One of them died of smallpox. The 3 natives who survived were educated at FrizRoy's expense.
The year after arriving in England, FrizRoy wanted to complete the research of the scientist King, who was on the first voyage of the HMS Beale, but he wanted a biologist with him. FrizRoy was good friends with one of the professors at the university Darwin attended, so FrizRoy asked the professor if he knew of any participants. The professor immediately mentioned Charles Darwin. Although Charles wanted to go, his father refused to let him go on the voyage with the Beagle because of the price he had to pay. The reason Darwin's price was much higher than the others on board was that he was not in paid employment. But his father was convinced by FrizRoy that Charles should go. The first few days Charles was on board the "HMS Beagle", he was very seasick. But even though he was seasick, he was lucky. There were many participants competing to join the trip. This became the most important voyage since Columbus.
On December 27, 1831, Darwin boarded the “HMS Beagle”. The voyage from England to Pahia, on the east coast of Brazil, took over a year and two months. HMS Beagle traveled extensively along the southern coast of America. Darwin was dropped off in Bahia Blanca, while FitzRoy led surveys along the Patagonian coast. Important discoveries and discoveries were made. They had dug up bones of extinct animals, including sloths, armadillos and llamas. Darwin saw that they had features in common with some of the animals living today. He believed that he was beginning to get evidence for the theory of evolution, which his grandfather had invented almost half a century earlier.
FrizRoy had also completed his project with his native people. Not long after the natives had returned to South America, they resumed their original way of life. In September 1835, the delegation reached the Galàpagos Islands. Darwin was amazed by the flora and fauna on the various islands. He looked for fossils and compared them with living animals. He then found that two or more animal races can indeed descend from one and the same species. Darwin found 14 species of finch on the Galapagos Islands. Among them was the "Tool-Using Finch", which used a cactus spike to catch food in holes in trees and in rock crevices. He saw that the tortoises always had 4+5+4, or 13 plates in their shells. The placement was the same, but the size, shape and edges of the shells were different. The plants and animals that they took back to England were carefully examined for new biological discoveries. They found 71 different plant species on the islands, 38 of which existed only on the Galàpagos Islands. 30 of the plants that existed only on the Galàpagos Islands existed only on James Island.
Darwin saw a lot on the trip with the “HMS Beagle”. One day while out riding, he spotted an armadillo burrowing into the sand before Darwin could get off his horse. He was surprised at how quickly it burrowed. The same day that the “HMS Beagle” arrived at the Galàpagos Islands, some of the crew spotted some large lizards that looked like dragons. They decided to pick Darwin up right away. Darwin and the rest of the crew, including Fritz Roy, arrived a short time later. The “dragons” did not seem to react or care about the crew of the “HMS Beagle”. Darwin had to find out if the “dragons” were really so peaceful. First he pushed one of them with the butt of his rifle. The “dragon” lost its balance but quickly got back up. Otherwise, there was no response from the “dragon”. Darwin thought they were not dangerous, but he wanted to be sure, and at the same time know if they were heavy. He grabbed one of the “dragons” by the tail and swung it around him. The crew of the “HMS Beagle” jumped. Darwin let go of the rope, and the “dragon” fell with a thud to the ground. The “dragon” no longer cared about Darwin or the rest of the crew. The lieutenant on board, Wickham, shook his head and said something like: “No one but you, Darwin, would be stupid enough to touch these creeps.” Darwin smiled and replied “Perhaps we could take one aboard, lieutenant?” What they called dragons were later renamed “Sea iguanas” or “Marine iguanas”.
On 2 October 1836, the “HMS Beagle” arrived in England. Personally, it was a brilliant success for FitzRoy. It seemed as if the voyage triggered depressions that were probably hereditary. He went to New Zealand as governor. It ended in failure. The colonists disagreed with his liberal attitude towards the Maori. Darwin wrote down in his notebook everything he had found out after he arrived in England.
Darwin's theories caused a big stir in the church. The priests did not like the theories because they offended and "opposed" the Christian faith. People were against parts of the theory. They believed that animals could have evolved from other animals. But they did not like the fact that we humans descended from apes. It was seen as an insult. Even though many later saw the similarity, they stuck to what they had thought before. The reasons could be many. Maybe because they did not want to be "bullied"?
It was not only in England that the discussions about the theories were, in Norway the discussions were also in full swing. Many people have been unsure whether they were for or against the theory that Darwin came up with. There were also many in the press who made fun of those who led, or were well-known and had a strong position in the discussions. A cartoonist in Aftenposten had made fun of Bondevik. Darwin of course became the victim of the same type of prank. In pictures they put Darwin's head on a monkey or a chimpanzee (see drawing). Many had misunderstood Darwin's theory. They thought Darwin meant that we descended from modern apes, but it was prehistoric apes that Darwin meant.
About 2 years after his return, Darwin became secretary of the Geological Society until 1841. In 1839 he married his cousin, Emma Wedgwood, and in the same year he was elected a Fellow of the Royal Society. His book, "Journal of Researches during the Voyage of the Beagle", was also published in 1839. The first draft of the theory of evolution appeared in 1842, and was expanded into a 230-page article in 1844. Due to ill health in 1842, Darwin moved to Down House, in Kent.
What Darwin meant by his theory of evolution, and what was the beginning, was as simple as: “All living things originate from a primitive biological primordial cell that suddenly arose from inorganic, non-living matter. From the primordial cell, plants, animals, and humans spontaneously arose by natural selection and struggle for existence.”
During the last year Darwin was very ill, and Emma played the piano for him every day. He died on April 19, 1882. He had experienced many wonderful and exciting discoveries in the world of thought. Some of those who had accompanied Darwin on some of his trips, or had been close to him, carried his coffin. The coffin was taken to Westminster Abbey, and placed in a grave next to Sir Isaac Newton.
