Cephalopods, such as limpets and octopuses, played a significant role to help us understand how animals build their own civilizations. Martin Wells, the author of “Civilization and Limpet”, provided a series of factors throughout the essay to guide the readers, also presented the core of how civilization works by the contrasting the human to the cephalopods. Wells first investigated about limpets, finding a probable answer to explain how limpets could return to the exact spot after several hours through the mucus tracking method. He then went in detail of how animals like other insects, birds, and octopuses, use different navigation methods to track and communicate. He went on and provided the readers with more informations about octopuses …show more content…
Wells made a few focus points shifts during his process of explaining, so that the readers could find similarities throughout the essay. From the beginning of the essay, Wells discussed about the mucus tracking method of how limpets are able to return to its original location, but he suddenly shifted to what methods limpet do not use. It seemed pretty odd at first, especially later on when the readers encountered the exact same situation. Wells digged deep discussing about octopuses and how they were taught to pause through shocking. After having a good understanding of touch learning and octopuses, Wells jumped and focused on what the octopuses cannot discriminate using touch learning. The reason why he structured it this way is to show the similarities of what these cephalopods are bad at, and helped to understand and identify what disadvantages they have to struggle with. Disadvantage such as simply having the lack of joints could make them lose informations on what they are touching, which could potentially present as a danger to these soft-bodied …show more content…
Wells stated,” Yet we are both here in our millions, and only one of us is bashing the ozone layer” (Wells 17). Wells brought up an interesting opinion for the readers to reflect on. As our technology becoming more advance, human are able to alter the surroundings to fit to our best needs, but not these soft-bodied animals. There are just as much of these cephalopods who are living in the ocean as the human who live on land, yet we single-sidedly creating harmful disadvantages for the cephalopods by polluting the planet. Wells referred the consequences of our actions as “bashing the ozone layer” to emphasize how impactful and critical our actions are endangering the Earth. We should look at limpets not only as a cephalopod, but also in the ways we are indirectly affecting them. In conclusion, “Civilization and the Limpet” by Martin Wells reminded us all about how our joints is the backbone to our way of process informations that hold up a civilization. At the same time, we have to also respect and recognize the cephalopods that do not have joints and still successfully living their lives. Wells presented a handful of informations, which I learned more than just limpets from this informative yet organized essay. Wells truly wanted the readers to comprehend and understand the importance of knowing what is one capable of doing, and improve from
The author fails to make compelling arguments on the environment since he does not use sufficient academic references for his information; and misunderstands the generalization issue. McKitrick
70 common limpets were identified in the 40m bracket identified as the littoral zone, between 0m to 40m. The common limpet employs a range of adaptations to survive the abiotic and biotic conditions associated with the littoral zone. Firstly, the limpet uses a structural adaptation to overcome the harsh wave action in the tidal zone, by using their radula to grip on to imperfections in the rock. Furthermore, they employ a behavioural adaptation of grinding their shells down into the rock, to further ensure they are not swept away by the tide. Additionally, the limpet utilises a behavioural adaptation regarding its tough shell and powerful radula, to defend against predators.
David Foster Wallace's article "Consider the Lobster" analyzes the agony that Lobsters feel when they are being bubbled invigorated to be devoured by Humans. He utilizes the lobster for instance to grow his examination, drawing out the relationship amongst people and the creatures that we devour. Wallace begins of his paper by saying the Maine Lobster Festival and its colossal horde of more than 80,000 individuals that devour more than 25,000 pounds of lobster amid the 5 days that the celebration keeps going. He begins off the paper with esteem in his tone as he depicts the Maine Lobster Festival to his perusers. After he's done lauding the celebration, Wallace uncovers
There is a common misconception about the field of paleontology. Many people believe it’s boring, that it’s irrelevant, and that it’s even a waste of time. However, as award winning paleontologist and author Neil Shubin argues in his novel, Your Inner Fish, the field of paleontology has the potential to change the way we view our bodies. Shubin rose to fame in the mid ‘00s after discovering a brand new fossil on the coast of Ellesmere Island. This fossil was of a creature that was part land animal and part fish, containing the flat head and joints of a land animal and the fins and webbing of a fish.
This is not particularly surprising as many of the chapters are written without a meaningful timeline and describe previous extinctions we no longer have control over. For instance, the sections dealing with the ammonites, dinosaurs, and mastodons have limited social commentary because of their general irrelevance to the modern world. However, Kolbert still refrains from voicing immediate action even when discussing the acidification of the oceans and coral bleaching. In the “Welcome to the Anthropocene” chapter, several statistics are rattled off including, “Fisheries remove more than a third of the primary production of the oceans’ coastal waters [and] Humans use more than half of the world’s readily accessible fresh water runoff” (108). Despite these seemingly worrisome conditions, Kolbert does not provide any direct opinion or action for us to follow.
Hannah Ton Mrs. Braun Honors American Literature 1 November 2015 SeaWorld Orca Breeding Should Not Be Continued When Dr. Heather Rally, a veterinarian who specializes with marine mammals, visited SeaWorld, she witnessed an orca with a severely collapsed fin and asked an “educational” guide why its fin was bent. The guide replied that it was a genetic trait just like curly or straight hair. However, Rally knows the truth, scientific evidence suggests that the high rate of dorsal fin collapse in captive orcas is due to conditions of captivity. These include spending an abnormally long time at the surface in direct sunlight and continuously swimming in tight circles.
Vertebrates are known to be animals with backbones. Tooth reduction is one of the major evolutionary trends that developed among major vertebrate groups that allowed for the transition from aquatic to terrestrial life. Evolution of limbs and being able to breath air are other evolutionary trends that took placeThese trends include improved respiration and protective and insulating body coverings. More over the transition from water to land also included changing to more efficient reproductive methods like having a placenta for some animals or egg layers for other animals. Lastly, the morphology of organisms evolved such that for land they would have paired, muscular appendages used for crawling and
One example of humans unknowingly killing our own planet was the invention of plastics. “The age of plastic” began as early as 1909 and the low cost of plastic made it easy to mass produce and distribute. About a century later, studies have proved that as much as eight million tons of plastic waste has been found in the ocean. An amount of waste of this proportion being dumped into the ocean has lead to the extinction of numerous species and the potential extinction of many more in the future. David believes that we as humans are extremely fantasized with planets and creatures that only exist behind a computer screen and that we should be more fantasized with learning about our own planet and what lies within it before it is too late to do so.
here is Ean 's writing: The Electric Eel Story Electric eels are related to catfish. Electric eels are mammals. They need to come up to the water surface to breathe in air. They live in murky streams around the Amazon river.
It said that a lobster’s nervous system is quite simple and it is ill-equipped to feel pain; however, Wallace explains that the claim is “incorrect in about nine different ways”(pg60). He convinces the reader by first of all displaying the information in an easy to read and unbiased way. Wallace then explains the anatomy of a lobster and shows the reader that lobsters have a centralized nervous system. Then, he uses a mixture of logical and pathetic appeal to demonstrate that lobster’s can sense the scorching hot water, by saying “Lobsters have pain receptors sensitive to potentially damaging extremes of temperature,”(pg63). While saying that, he reports the “struggling, thrashing, and lid-clattering” which occurs when the lobsters’ are in a boiling kettle, Wallace asserts that due to the lobsters’ behavior and neurological build-up show that a lobster can perceive pain, by saying that a lobster’s action show a preference to not get boiled alive, and this preference leads to the lobster suffering.
By this I mean, the gases that many people use every day, are harming the air. In the anchor text, “Nobel Speech,” written by Al Gore, he talks about the effects of climate that many people use every day, are harming the air. In the anchor text, “Nobel Speech,” written by Al Gore, he talks about the effects of climate change and how we affect it. In the text, he states, “So today we dumped another 70 million tons of global warming pollution into the thin shell of atmosphere surrounding our planet as if it were an open sewer.” (paragraph 11, pg. 374).
Gould and Lewontin finally come to the conclusions that the constraints placed on natural selection are possibly the most important part of evolution because these constraints restrict the pathways of natural selection so severely. One category of constraints is phyletic constraints, which affect how a species can evolve based on it’s history. One important example of these is developmental constraints in which the early stages of development are both highly conserved and strongly restrictive, allowing for only a few possible adaptations to occur. The other kind of constraint discussed is architectural constraints, which arise as architectural restrictions that never were adaptations, but rather the necessary consequences of material and designs selected to build the basic body plan. This is where the concepts about architecture from the introduction come into contact with and highly relate to the body plans traits of modern organisms.
BIOLOGY RESEARCH ESSAY There is great speculation around evolution. As we are continually in the process of discovering the history of human beings, there are many questions surrounding this topic. One very interesting question is why ancient ancestors of homo-sapiens evolved to walk upright like we do today. An apes’ DNA is astonishingly similar to that of a humans, (97% the same) and yet, our bones’ shapes and structure are very different.
Dolphins are mammals, breath air, give birth and nurse their young ones. The ancestors of dolphins were animals that once lived on land but turned to the sea about 50 million years ago and never returned to land hence the dolphin’s ancestor had to slowly adapt to its new environment. Its front legs became flippers and its tail became flukes that it uses for swimming and steering respectively. The same bone structure is shared by bats, flying mammals in the order Chiroptera. While the trait for them was inherited from a common ancestor, the bones that form flippers in dolphins form a bat’s wings (homologous trait, example of divergent evolution) Its back legs diminished completely into the body.
They are very unique in many different ways and a crucial support for human life. They play also a very important role in the marine life such as giving shelter and food for millions of species including fishes, crabs, or shrimps. They support 33% of marine fish species. They also have specific and certain conditions to be formed, and to survive. They are also known as the “rainforest of the oceans” because of its huge diversity.
