Regarding “Charles Darwin and the Tree of Life”
When Sir Charles Darwin set sail on the Beagle in 1831, the way in which humans view the biological world began its shift towards where it currently sits today. The observations which Darwin made during the voyage set the stage for his formulation of the theory of Natural Selection, resulting in a shake-up of the standing scientific establishment, and in the way in which humans view the world in which they live. During the many stops which the Beagle made on its multi-year journey, Charles Darwin documented and collected samples of the native species present at the places where the ship dropped anchor. In so doing, Darwin was able to witness and document a wide range of species across a wide

In part, Darwin came to this conclusion because of anatomical patterns which are present in several different animal families. In a way, it is possible to track the relative progression of animal life on earth based upon the similarities and differences of different groups. Darwin noticed that Reptiles, Amphibians, Birds, and Mammals all share similar patterns in the way in which their skeletons are constructed. In nearly all cases, the basic pattern for limbs consists of a “One bone, two bone, lots of little bones” type pattern, as well most possessing at least five digits on the hand. This pattern points to all of the members of these groups, both living and extinct, tracing their lineage back to a single ancestor which migrated to land at some point millions of years previously. As well as anatomical patterns, evidence from the fossil record also points to a singular origin. The discovery of Bird like Dinosaurs such as Archaeopteryx, a species of Dinosaur which displayed features associated with both Birds and Dinosaurs such as feathers adapted for flight, clawed hands, and a mouth with teeth. Though species such as Archaeopteryx were primitive in their flying capabilities, they provide for a good approximation point of the beginning for the only family of Dinosaur which exists today, the Birds. By connecting similarities in existing and extinct species, it becomes …show more content…
For example, Amphibians have evolved from fish to be able to live both on dry land, and in water. However, because of this dual lifestyle Amphibians are not able to travel far away from a large source of water. This is due to the need of Amphibians to keep their skin moist at all times, as well as their need to lay their eggs in water. However, this problem has been solved by Reptiles, which have evolved from Amphibians to be able to live full time on land, due to their dry, non-permeable skin, as well as their ability to lay eggs inside of a protective shell which holds in the moisture necessary for the young to
The documentary, “Darwin’s Dangerous Idea” tells the story of Charles Darwin’s conception of his theory of natural selection, and how it explains the evolutionary process and species adaptation. The story begins with a brief overview of his 5-year stint on the HMS Beagle as the ship's naturalist, during her South American voyage. The film shows how Mr. Darwin collected fossils and many species of animals and birds from many different regions especially the Galapagos Islands. It portrays Mr. Darwin’s return to England and his struggle between the mainstream religious beliefs and his personal beliefs of how different species came to be. Additionally, the documentary covers his presentation of fossils and ideas to the scientific community,
There are numerous counts of evidence showing the processes of evolution and how species ultimately evolved over millions of years. One of the most compelling hypotheses behind evolution was presented by Charles Darwin with his study of the Galapagos Islands. His study showing the various different birds and their different evolutions they went through to be able to survive the changes of weather and relocation. The birds he studied had to change in order to survive, or as he simply puts it: “Survival of the Fittest”. Evolution is the changing of past organisms to diversify and have the ability to fit better in their environment and survive. Diving into the dinosaur cladogram, studies have shown that ancient dinosaurs, over hundreds of millions of years ago, evolved into our modern day birds, and not lizards as many suppose. It became apparent that there would not be enough food for a 9 ton dinosaur to consume on a daily basis forever. So evolution occurred and dinosaurs evolved to become more efficient so they could survive more effectively in their
1. what was the original purpose of Darwin’s voyage on the H.M.S. Beagle, and what was the ultimate significance of the Voyage?
However, his passion for natural science never swayed. It was this intricate fascination that brought Charles about meeting Professor John Stevens Henslow. Henslow was a specialist in botany. Overtime Henslow and Charles became quite close friends. In the article titled: “Charles Darwin: man behind monkey” author Christine Dao further explained the following events after the fact that Charles and Henslow became close friends. Henslow had the opportunity to accompany Captain Robert Fitzroy to the Americas as a naturalist. He extended this opportunity to the “novice” naturalists Charles. Dao’s article states, “Henslow proposed that Darwin take his place on the HMS Beagle journey to the Americas as an unpaid naturalist and gentleman companion to Captain Robert Fitzroy. Darwin was almost a complete novice, his experience based only on rudimentary geological studies, beetle-collecting, and the dissection of marine
Although Darwin’s (1809-1882) work in evolutionary observation might appear radically different from those focused on other areas, the theories he developed from these observation lead to such groundbreaking publishing’s as The Origin of Species. These intern caused an upset within the then accepted norms of philosophy and religion, had a profound impact on the academia, and further
Darwin was the British naturalist who became famous for his theories of evolution and natural selection. Like several scientists before him, Darwin believed all the life on earth evolved over millions of years from a few common ancestors. From 1831 to 1836 Darwin served as naturalist aboard the H.M.S. Beagle on a British science expedition around the world. In South America Darwin found fossils of extinct animals that were similar to modern species. On the Galapagos Islands in the Pacific Ocean he noticed many variations among plants and animals of the same general type as those in South America. The expedition visited places around the world, and Darwin studied plants and animals everywhere he went, collecting specimens for further study.
Darwin’s observations from the islands made him want to come up with some explanation to why this occurred. He began to do research of each the species that had lived on these islands and observe all of the
After the long five year voyage, Charles Darwin published his book, “The Voyage of the Beagle” in 1839 which showed his findings and observations while on the expedition. He would later publish a total of twenty-five books in his lifetime about the field of science. His ideas and theories were criticized by creationists who his ideas disproved and contradicted their belief of Creationism, or “the belief that the universe and the various forms of life were created by God out of nothing. It is a response to modern evolutionary theory, which explains the emergence and diversity of life without recourse to the doctrine of God or any other divine power” (Britannica.com 1). He would still, however, believe in his work until his death on April 19, 1882. By then, people have already accepted his ideas on evolution and natural selection, which would become to be known as
Throughout his university career, both at Edinburgh and at Cambridge, Darwin continued to receive offers to explore and go on expeditions with various mentors, colleagues, and teachers. On these trips, he collected marine animals from tidal pools (Darwin, p. 50), worked stuffing birds as an apprentice (Darwin, p. 51), and went on a voyage documenting fossils with Adam Sedgwick (Darwin, p. 70), among other excursions. He also developed an extensive collection of beetles and developed a system of capturing and documenting
In 1835 Charles Darwin, aboard the vessel HMS Beagle, first set foot on the Islands of the Galapagos Archipeligo setting off on what would become the inspiration for the most important innovation in biological sciences either before or since. That visit solidified for Darwin his notion of the evolution of life on Earth, and helped trigger his breakthrough regarding Natural Selection, ultimately culminating in his groundbreaking masterpiece On the Origin of Species by Means of Natural Selection. And although Darwin would never return to these Islands in his lifetime, the Galapagos still hold today a vast importance-both symbolic and scientific-to evolutionary biologists everywhere, and have undergone intense scrutiny and
Through his connections Darwin eventually joined the H.M.S. Beagle on a navigational trip around the world. There is some debate as to whether Darwin was the official ship's naturalist; by some accounts he was only a passenger, because he lacked a degree in the natural sciences. At the time of his departure, Charles was also creationist, meaning that he held to the Biblical view of the origins of the earth and its creatures. He spent five years traveling on the Beagle, collecting specimens of things he encountered in his travels. He never adapted to sea travel, and was sick for most of the time he was on the ship; when his travels were over, he settled down permanently.
The original purpose of Darwin’s voyage on the H.M.S. Beagle was to find evidence that could prove the biblical theory to be true, and to discover and chart the South American coastline which was not well known. He was to collect specimens of rocks, plants, minerals and animals along with observing and recording them. The ultimate significance of this trip for Darwin was rather than being able to prove that the biblical theory, he had evidence of evolution by natural selection. He found fossils of Glyptodont and Megatherium which were very similar to the common armadillo which led him to question whether the Earth was 6000 years old as it was believed to be or much older than that, and when collecting the common bird discovered differences
Charles Darwin was a man who shaped the way in which we think about evolution in modern times. He brought forth and described the theory of natural selection and survival of the fittest. To fully understand modern evolutionary thoughts it is necessary for one to completely understand the early theories of Charles Darwin. In this paper I will provide the reader with a complete background on Charles Darwin, describe his voyage on the HMS Beagle, and discuss his theory of natural selection.
After school Darwin became naturalist on board the royal navy ship the Beagle. The Beagle left England on December 27, 1831 this was a small ship with a crew of 74, Darwin had a small laboratory and a hammock to sleep on, he suffered bad seasickness. Darwin’s job aboard the Beagle allowed him to study on many different continents. He
