Unit 1 KEY QUESTIONS Essay

Have you ever wondered about why Charles Darwin was so important? Charles Darwin was an amazing scientist. Born February 12, 1809. He grew up in a small town in Shrewsbury, England with six other siblings. He was the second youngest. His father was a doctor and was hoping that he would do the same when he got older, but it wasn’t for him. So he was always a risk-taker because even though his dad would’ve been mad he still went for his own way studying nature. He went to Christ's college in Cambridge and graduated from there. Darwin was always interested in nature, so when he went on a voyage. This tells us about how Darwin was always been interested by nature.

For most of the five year expedition the Beagle actually spent the majority of its time surveying the Southern Coast of what is today known as Argentina and Chile. It was in Latin America where Darwin made many of his most important discoveries that had a lasting influence on his future work and evolutionary theory.

Upon his return to London Darwin concluded thorough research of his notes and specimens many ideas. Out of this study grew several related theories: one, evolution did occur, two, evolutionary change was gradual, requiring thousands to millions of years, three, the primary mechanism for evolution was a process called natural selection, and four, the millions of species alive today arose from a single original life form through a branching process called "specialization."

Some consumers claim GMO’s do not increase yields or even result in lower yields. Arguing these statements Monsanto, an agricultural company, states, “In agriculture, desirable crop characteristics are known as traits. One of the most important traits is yield. Improving crop yield can be accomplished through both breeding and biotechnology. GM crops generally have higher yields due to both breeding and biotechnology”. The statements revolving around the anti-GMO myths are continuously being revoked as further research comes out. By increasing yields, farmers are able to sell more crops which in return can have a positive effect on the economy. Geoffrey Lean, who published a story in the UK newspaper later, claimed his article on GMO reduced yields based on Dr. Barney Gordon of Kansas State University’s manganese research was given a rebuking response. Dr. Gordon himself claimed Geoffrey Lean’s work was “a gross misrepresentation of my research and a good example of irresponsible journalism”. While the yields were more relevant in

World Book tells us: (2)". . .The study of the specimens from the voyage of the Beagle convinced Darwin that modern species had evolved from a few earlier ones. He

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

When Darwin traveled over to the Galapagos island he traveled on a ship called the HMS Beagle. Darwin traveled to the Galapagos island to get information about evolution with the animals there. When he was there he observed tortoises, when he observed these animals he got a understanding of evolution over time. He saw that the tortoises in the area with food low to the floor had a flatter shell and a short neck, but when he observed tortoises with food high up he saw that the tortoises had a long neck and raised shell. Over time the tortoises evolved she they can survive in their environments. When he was their he wrote a book called the Darwins book on the origin of species. The information that he wrote about was information about species that were not fixed but could change over time by natural causes.

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 1837, Charles Darwin was traveling aboard the H.M.S. Beagle in the Eastern Pacific when he stopped on the Galapagos Islands. There, Darwin found a wide array of animals including the Galápagos finches. The differences that he uncovered between these animals sparked Darwin’s interest; he had never before seen nor attempted to understand the similarities and differences inherent within these species. Examining each and uncovering the probable reasons for their distinctions, namely their differing needs for adaptation, Darwin constructed his theory of natural selection. From his observations on the Galapagos Islands, Darwin continued developing his research into eventually what became known as the Origin of Species, published in 1858. In this book, he asserted that these animals and differing species did not just appeared out of thin air, but rather had evolved from other species through the process of natural selection. Yet, his scientific findings were not accepted by the general public when first published, nor long after. Instead, they sparked a great uproar and criticism, since for most people accepted the theory of the Creation, the belief of divine creation, as the way people and species appeared on earth. His findings, so contrary to the then accepted norm of creation, were met with hostility and resentment by many who considered his work

The governments and scientists were hoping that the GMO’s will provide to the public such benefits as increased food supply, helping underfed nations, assisting farmers, and better overall food taste. Because the crops are already resistant, this would allow farmers to skip steps in the production process, like spraying herbicides and pesticides.

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

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

Previously, he had been inspired by Charles Lyell’s Principles of Geology, which stated “present conditions and processes are clues to Earth’s past history.” While on the Beagle’s journey, Darwin sent home a total of 1,529 species that had been maintained in spirit as well as 3,907 desiccated specimens with labels (Biography Online). A breakthrough in Darwin’s studies was when he noticed certain forms of organisms subsist in particular areas, as well as that a wide variety of organisms had previously gone through changes that enabled them to stay alive in their particular environment (Notable Biographies). For instance, he studied the Finch in the Galapagos Islands and noticed that there are over twelve different forms of this one bird. These bird’s beaks were different sizes and shapes, depending on what food was available in their particular area. The animals on the Galapagos Islands showed many similarities to other animals in other parts of the world (Biography Online). Between the discovery of the different Finches along with the similarities of animals from other locations, he began to wonder if there was something more to earth’s history. These observations would later lead him to his theory

A key factor of Darwin's evidence on the evolutionary process was the Finche. During his travels to the Galapagos Islands Finches became the main evidence to support his theory on the evolutionary process. Darwin was able to identify Finches that had various shaped beaks. Studying them more in depth he was able to establish the reasoning for these changes creating his theory of natural selection and gradual evolution over time. With the ability to draw and write, Darwin had little struggle documenting his findings during his time on the H.M.S. Beagle. Darwin was also able to ship species and labeled dried specimens back to his home land. At the time of Darwin believed his new founding to be very hard for the world to adjust to his new found

Darwin worked his hardest during the voyage, simply because of his pleasure of investigation. He also worked his hardest because he wanted to add some new information into the many more facts there were in the world of natural science.
