“The glue is not one thing; it is a variety of different molecules that connect and lie between our cells” (123). This glue and molecular structure gives each cell and tissue their distinct functions. What makes many different body parts different is how the materials like cells and tissues are arranged and attached to each other, like the eye and leg. This indicates that every tissue alignment is different in it’s own way and can be identified with it’s organism. The author had his students try to identify each tissue under a slide and it is possible, but very…
Kelly seweyn Per;5 Is the Norway Rat an Invasive species that is what we going to be learning about in this paper including other non-invasive and invasive species but first we need to know what they are so you can talk away your best view from this paper. A invasive species have few natural predators, have high reproduction rates, are long lived, are pioneer species (meaning they were brought here from other places ) , They are generalists, they kill native species, produce abundant seeds, tend to flower early and spread rapidly. But today we are learning about the Norway Rat and if that is a non- invasive specie. The Norway Rat and the rattus norvegicus are the most common rat in the U.S.A, they are covered in shaggy fur and are either a brown or gray color.…
Why do we look the way we do? What does the human hand have in common with the wing of a fly? Are breasts, sweat glands, and scales connected in some way? To better understand the inner workings of our bodies and to trace the origins of many of today's most common diseases; we have to turn to unexpected sources: worms, flies, and even fish. In Your Inner Fish, Neil Shubin clears up the questions previously asked.…
In a book titled “Lone Survivors” by Chris Stringer, Stringer presents to us his interpretations of the origin of modern humans. Previously, there were two fossils including a tooth and a finger of a female and male, found in the Denisova cave of Siberia which revealed a species that was perhaps indirectly related to both the Neanderthals as well as Homo Sapiens. In addition, they have unique features that are enough to separate them to their own distinct species. These fossils convinced Stringer that perhaps modern humans today are not a pure species but rather a mixture of other hominid groups. Neanderthal genes may still be in us.…
Explaining Evolution Evolution has always been a relevant topic, whether being explained in learning environments or thoroughly investigated by scientists, why is it so important? Evolution tells the story of how humans, as well as other species, came to be. The articles “12 Examples of Evolution Today” by Erin Brodwin and “A Possible Break in One of Evolution’s Biggest Mysteries” by Peter Brannen are both compelling with the information they provide, and contain insights into the world of evolution. Brannen’s article is specifically focused on the whale and studying the barnacles on their bodies to gain more knowledge on the story of their evolution, whereas Brodwin’s article is broader and shares information on different species that evolved…
I was awarded the opportunity to attend an event hosted by the University of Vermont Medical School. It was held in recognition of the Anatomical Gift Program. In celebration and expression of gratitude towards organ donors and their families, the medical school courteously organized a day of education appealed to students who exemplify an interest in medicine. The experience comprised of a demonstrative and informative exploration of the cadaver lab.…
Chapter VII: Miscellaneous Objections To The Theory Of Natural Selection Chapter VIII: Instinct Chapter IX: Sterility In these chapters, Darwin continues to disprove objections to his theory. In Chapter VII, Charles Darwin rejects an enormous amount of minute insignificant objections to his theory. He disproves each small objection with what reads as him being insulted by the lack of intelligence of his persecutors.…
Who would of know that the discovery of a small fragment of a human cranium parietal bone would be so controversial to the understanding of human evolution? Even though we had already found human ancestral remains that contributed to the thoughts of modern humans this new piece of the puzzle created a ripple not only in the way schools were taught but also the way humans saw religion. But it wasn’t till the connection between primates and humans that flipped the world upside down. This discovery posed a conflict with the biblical timeline that most religions believe in; do we suddenly change our perfectly created understanding of the way we were created just because a small piece of what may be human remains while stifling the growth of science…
I think rat is too small for comparing to human. I have no idea why rat is used to explain to neglect as a child affects the human’s brain. It was interesting for me, and I wondered about it.…
Journalist and author, Elizabeth Kolbert, in her book, The Sixth Extinction: An Unnatural History, argues that we are living in the midst of a man-made sixth extinction. Kolbert’s purpose is to illustrate the ways humans are provoking the sixth extinction. She creates an informative tone in order to appeal to her adult reader’s logical thinking. Kolbert relies massively on the persuasive appeals, Logos and Ethos, to create the argument that man has, in fact, evolved over time. By employing this technique, Kolbert successfully argues that man’s evolution is possible and combats the primitive ideology that man, never has, or will, evolve.…
Since the emergence of the genus Homo, the hominins went through great patterns of evolution over generations. Through series of adaptations, the genus Homo spread in various geographic locations and eventually emerged as anatomically modern humans. With the allele frequency changes that evolved in the genus Homo, there is key evidence that microevolution led to macroevolution. From speciation to extinction, the modern synthesis helps us explain not only the mechanisms of evolution and the reproductive barriers between species, but also the various social adaptations that changed the hominins over time. From 2mya to ca.…
In Neil Shubins’ “Your Inner Fish: A Journey Into the 3.5-Billion-Year History of the Human Body”, he takes the audience on the journey of the discovery and history of how different organisms and adaptations have converged to form a relationship between fish and tetrapods. Shubins first relates the evolutionary fact that humans and other forms of “tetrapods’ major body systems have developed from fish and sharks” (20), through his time on the field as a paleontologist. He describes his multiple experiences of planning, preparing, excavating, and analyzing not only the fossils found by his team, but also where and when in the rock these artifacts were found. His research and expenditures led to discoveries of bones and fossils that he would…
The evolution of human beings has been a major research area with controversy being whether human beings evolved from the chimpanzee. Based on various theories and research reports that have been presented, scientists believe that a common ancestor to humans existed about 5 to 8 million years ago (Drake, 2015). It is believed that humans evolved from the modern apes such as the gorillas and the chimpanzees more than the monkeys. In the quest to find out the real answers regarding the origin of humans, I decided to find out through research.…
In the movie I, Robot we are introduced to a long debated philosophical question: “What makes a human being human?”. Is the essence of mankind the fact that we are biologically unique among the myriad of different species on this planet? Is it the fact that we seem to have transcended our baser needs in order to try and make the world fit us as opposed to us fitting into the world around us? Is it perhaps that we have what people would call a “soul”? Or is it possibly that we were said to have either evolved from our animal counterparts, the primates, in order to be what we consider better?…
Potions, pills, mystery ointments. All of these have and are being used to prolong human life. The need to stay young and alive has been around since the birth of mankind. From the ancient alchemists of medieval times, to today’s most specialized doctors, humans are always working towards the next miracle to keep them alive. Mankind will always strive to survive, no matter the circumstances, because they are hard wired to make choices which will give the best chance of survival.…
