The article states that the discovery made by the scientist about the fossils of animals contain red blood cell, blood vessels, and collagen matrix, and provides three reasons of support. However, the professor explains that discovery about a dinosaur are skeptical, and refutes each of the author’ s reasons. The reading claims that the soft deposits left inside the bone hollow were the remnants of blood vessels. The professor refutes this point by saying that a soft organic substance are not the remnants of blood vessels. The professor says that these were the material which were left by a bacteria because they lived in the hollows in the bones of animals when they died. He says these were the traces of moist residues that were left by colonize
While the author of the article believes that Brachiosaurus were aquatic animals, the professor disagrees with this statement. The professor points out that in spite of the fact that some species of dinosaur would spend a great deal of time in water, there was no possible that Brachiosaurus were aquatic ones. To strengthen her point, the professor provides sufficient evidence respectively to the points made in the article.
The reading passage proposes three theories which support the idea that a dinosaur which is called edmontosaurus survived in the winter by migrating to the south, the more hospitable region than the extremely cold in the North Slope. However, the professor in the listening respectively contradicts each theory in the reading passage by using strong evidence as support.
Fossil discoveries are extremely significant to science and they help people better comprehend the world they live in. Without these discoveries science wouldn’t of grown like it has and people would not know much about the Earth. The fishapod and the dinomummy are two fossil discoveries that have made a gigantic impact on science. The fishapod helped fill the gap between land animals and water animals and the dinomummy proved that dinosaurs vertebrae are different than scientists have been placing them. However, the most important part is the preservation of these two ancient creatures. If they hadn’t of been preserved like they had, then they would never of been discovered and scientists wouldn’t get to learn from the remains of these creatures.
From both the title of the chapter and the introduction by Dr. Shubin, this chapter begins with a focus on teeth. Because the function of teeth is to break down food before it enters the esophagus, the different shapes of teeth can represent many different things about the organism it belongs to including what type of eater it was (carnivore, herbivore, or omnivore). Teeth are the hardest tissue (not bone) in the human body and therefore fossilize well. As Dr. Shubin stated in chapter one, there must be many points that permit a fossil to make any kind of scientific conclusion. Obviously, the state of their presence is important, so the fact that teeth preserve well allows for them to be great specimens for analysis. Dr. Shubin and his team analyzed fossilized teeth in areas as different as Nova Scotia and the Arizona desert. Studying different fossils in these diverse regions allowed the team to see that mammalian and reptilian teeth are very different. For example, mammalian teeth differ from organism to organism to fit with the organisms need (Cheetahs that eat only meat will have different teeth than deer who are herbivores) and are replaced only once in the lifetime of the organism while reptilian teeth are usually sharp and are constantly replaced if damaged. These differences allowed scientists to characterize fossils as either a reptile or a mammal. Similar to Tiktaalik discussed in chapter one, the discovery of fossils that were part reptile and part mammal allowed the researchers to see that mammals evolved from reptiles, and further supported the theory of evolution. Further studies yielded even more
Second, the author thinks that business in selling the fossils, reduce the access of scientists to these fossils as a great source of scientific evidence, but the professor explains that all fossils need scientific evaluation by scientists for price marking, so all fossils are
Chinese immigration to America began as early as 1838 and continues on to this date. The time period of Chinese immigration is broken up into three periods, 1849-1882, 1882-1965, and 1965- present. 1848 was when the first mass immigration of Chinese citizens to the Unites States came about . Immigrants flooding to Northern California for the same reason why thousands of other American born citizens were flooding to California, the thought of striking it rich in gold. However, because of the large number of laborers entering the country the U.S. government passed the Chinese Exclusion Act in 1882 which prohibited the entrance of Chinese laborer into the country for ten years. Due the second world war and the bombing
Although the Ediacaran period was well before the first appearance of dinosaurs it shows that there were fossils many years ago. When dinosaurs first appeared things had changed there was still shallow water which meant that bones could be fossilized.
Every so often a discovery is made that attempts to shake up pre-conceived notions of how the dinosaurs actually lived or how they came to be. On June 22, 2000, in Oregon, scientists announced the discovery of the oldest known animal to have feathers. Though no records indicate how the age of the animal was determined, the
The article that I chose for this assignment is about the recent discovery/confirmation of the first known dinosaur which lived and thrived in the water. The Spinosaurus aegyptiacus was found and collected by Dr. Nizar Ibrahim from the University of Chicago. Ibrahim along with his colleague Dr. Paul Sereno determined that based on the fossil discovered that the specimen was a swimming dinosaur. Technically, the bones of Spinosaurs were first discovered 100 years ago by a German paleontologist in Egypt. However, these bones were only a sample of the full skeleton and they were stored in a museum in Munich, Germany which was later bombed by the Allies during World War II; thus
What is reality? The answer to that question can vary depending on the person asked. The phrase "perception is reality" means that the way someone interprets or understands something can affect the way they view the world as it really exists. The film Inception greatly proves this phrase to be true through its characters. The film is about a man and his team on a mission to implant an idea into a strangers mind while in a dream.
Jurassic Park by Michael Crichton demonstrated many dinosaur characteristics and behaviors. The dinosaurs were fictionally characterized to appeal to the readers. By examining the dinosaur’s appearance and behaviors of dinosaurs such as the duckbilled dinosaur, velociraptor, hypsilophodontids, dilophosaurs, Triceratops, apatosaurs, Tyrannosaurus rex, stegosaurs, and maiasaurs distinguished whether the evidence existed in the field of paleontology. The behaviors and characteristics of the dinosaur are divided into three factors as behaviors that were supported, not supported, and no evidence to support or refute the behavior.
Collaboration involves working together with others as members of a team with the intention to achieve a common goal. For example, in the nursing profession, the various departments in the health care organizations collaborate to ensure that long and the short term patient outcomes are met within the required time frames. Goals are stated and particular projects introduced to achieve the goals so that the members remain focused on the goals until the objectives are achieved (Carryer, et al 2007). Cooperation involves allowing the mutual actions without any form of obstruction. For example, if an investigation is introduced regarding the particular behavior of the nursing staff, such employees would
Nuclear power. It's the cheapest form of energy, but it is nonrenewable. Nuclear power doesn’t release carbon dioxide in the air, although, it pollutes water, and the air. These are many reasons to build a nuclear power plant, and to not build one. I say, you shouldn’t build one. This is why you should not build a nuclear power plant in our area.
Based on color, the cartilage was whitish in color while the bone was cream colored. The cartilage was relatively more flexible than the bone. On composition, bone is made up of calcium while cartilage is made up of hyaline materials. Upon piercing with a knife, the bone is resistant to piercing. On application of more force, it cracks and breaks unevenly as compared to the cartilage that is less resistant to piercing and was cut clean through upon application of a relatively lesser
In the science of paleontology, the history of life is studied. Paleontologists study fossils to learn the past ecologies, evolution, and the origins of humans. In order to understand the processes that have led to both the origination and destruction of organisms since life began, paleontologists incorporate both scientific knowledge and studies. Fossil findings are critically important for confirming predictions of evolution theory. Of the many discoveries that are made yearly to add depth to the understanding of evolution, an example is a recent discovery of a creature they named Tiktaalik. The Tiktaalik was uncovered to be a transitional animal between shallow-water fishes and limbed animals. The creature supports the idea that it emerged from both mammals and reptiles, suggesting that the two are related. These findings support prediction of evolution, contradicting the belief that God
