"I am turned into a sort of machine for observing facts and grinding out conclusions."

Charles Robert Darwin was born in February of 1809 in Shrewsbury, England and was the 5th of 6 children in his family. Darwin was born into a very wealthy family that had a lot of connections. His family members had all been very successful and Darwin lived a priviledged childhood. Charles’s father was alive for most of his adult life and worked as a local physician and a financer. Unfortunately, his mother died at a very young age, when she was only 52 years old.
Darwin attended a nearby board school in Shrewsbury during his childhood, but after graduating that school, he decided to attend Edinburgh University in October 1985, along with his own brother to study medicine. Darwin was studying to become a physician, much like his successful father had done. While at Edinburgh, Darwin found himself studying marine invertebrates with Robert Grant, one of the most well known biologists of the early 19th century. Darwin soon realized he did not like the field of medicine after he couldn’t stand to see blood or suffering of humans for a regular basis and believed surgery was a form of human brutality, so he quickly left the medical field of study.
Immediately after Darwin left the medicine field, his own father proposed that he get more involved in the church as an alternative. Darwin liked the idea of being able to pursue natural history, and in 1827 became a student of Cambridge University to study theology, with the goal later on of becoming an Anglican parson. While at Cambridge, Darwin studied a lot of the scientific ideas and papers written by geologist Adam Sedgwick and naturalist John Henslow, who were big believers in the idea of evolution of natural species. At the time, Darwin was not a true believer in evolution yet but was exposed to the scientific beliefs behind the theory quite often in his studies.

From 1831-1836, Darwin was able to journey on the HMS Beagle, a ship whose mission was to travel around the world in search of new scientific discoveries. Darwin served as the naturalist on board the ship, collecting thousands of specimens from various countries around the world, mostly being from South America. Darwin later called this trip across the oceans, “by far the most important voyage of my life.”
Throughout Darwin’s life he continued to study the natural world and later published his most famous book, On The Origin of Species to help explain how evolutionary selection occurred amongst throughout the course of their existence on Earth. “Natural Selection” and “Survival of the Fittest” were some of the scientific terms that originated from his studies published in the book. These theories have laid the ground work for modern scientific evolutionary studies and research going on years later.
Darwin lived to be 73 years old, dying in April of 1882 and was buried in Westminster Abbey. His legacy in the scientific community continues to be respected and celebrated for all the significant contributions he made throughout his lifetime.

Charles Darwin’s education at both Edinburg and Cambridge was never as a geologist, but he found himself studying the geological structures because of his natural curiosity for science. He was said to be “self-taught” in the concepts of geological phenomena and structures. Darwin was actually an accomplished geologist before he became a successful biologist, publishing his most famous work. He actually published a few pieces of work on the geological structure of coral reefs and volcanic structures of off the coast of South America in the Galapagos Islands.
Darwin began his HMS Beagle voyage under the captain Robert FitzRoy.

As a gift aboard the ship, FitzRoy actually gave Darwin the first volume of Charles Lyell’s Principles of Geology to help him become better acquainted with that field of science. One of Lyell’s principles in his textbook was related to a steady state, non-directional Earth where land alteration processes such as deposition, erosion, and uplift altered and changed a landscape. One of Darwin’s early exposures to geologic formations was in February of 1835 when he experienced a strong earthquake while exploring the area of Chile. Darwin claims that he saw visual evidence of a strong uplift of several feet in the area he was located in.
In further studies done by Darwin and principles discussed in the text, Darwin hypothesized that the coral reefs in the Pacific Ocean developed because they were bordering other landmasses that were being subducted downwards – producing three formation stages of coral reefs (Image 1). This related to our modern ideas of plate tectonics because along fault boundaries there is direct evidence of landmasses creating a subduction zone. This hypothesis was made remarkably before he even saw the coral reef himself. Darwin was also able to test his coral reef hypothesis a year later in the Cocos Islands, off the Northwestern coast of Australia, by examining the reef’s structure that formed in this set of islands also.

In 1842, Charles Darwin published a book titled, The Structure and Distribution of Coral Reefs. In this book, Darwin published a map inside of the southwest Pacific Ocean. Darwin’s hypothesis proposed that three stages of coral reefs (fringing, barrier, and atoll) were concentrated along certain coastlines and boundary lines of specific continents. Darwin discovered that coral reefs have a lot to do with the geology of this part of the Pacific Ocean. Fringing reefs, he claimed, were concentrated along continents that showed evidence of rising geologic areas. On the other hand, atoll and barrier reefs are more located in the central parts of an ocean in which the landmass nearby is sinking. We know today through the plate tectonic theory that subsidence of a landmass is due to the cooling of that material. When the material begins to cool, its density begins to increase as it moves farther away from an active ridge or hot spot.
Darwin was a very rigorous naturalist his entire life, devoting a good majority of scientific efforts in the field of biology. His major scientific theories are listed below.
