Magellanic Penguins Evolution

The Emperor Penguin lives in Antarctica on the Antarctic ice surrounded by very cold water. They are the largest Penguin to live with an average height of 45 and weigh on an average of 66lb. They are also considered the most beautiful of all penguins that live right now. The Emperor Penguin has big heads, thick necks, wedged shaped tail, and tiny flipper-like wings. They feed on fish, squid, krill, and cephalopods where they catch it by diving into the ocean up to 700 feet. They remain under the water for about 18 minutes while finding food. Both male and female penguins look very much alike with the same colors and same size. To identify them, you would have to check their behavior to see which one is a male or female. The female

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,

Over the last several years, evolution has been playing an increasingly important role in determining how various species are evolving. This is because ecology will have an impact on how quickly a particular organism is able to adapt (with: the unique challenges for a particular environment). To determine the effect that this is having requires carefully examining different species over the course of many years. This will be accomplished by comparing these changes on Darwin and Wallace Islands. Once this occurs, is when specific insights will be provided that are highlighting the underlying challenges affecting the development of organisms. This is the point that these transformations will be evident among the various life forms. (Fasolo, 2011, pp. 53 68)

The Beak of the Finch by Jonathan Weiner explores evolution through the most famous examples in history—the finches of the Galápagos Islands. Charles Darwin’s theory of natural selection and the process of evolution are applied directly to what scientists refer to as Darwin’s Finches. Weiner follows scientists Peter and Rosemary Grant as they study the finches in real time on the Galápagos. Years of previous work, study and data is collected and analyzed. Different species of animals are observed and explained throughout history. The Grants have one goal, and that is to find the origin of the species, how organisms first began. They find that it really is about the “survival of the

The Evolution Lab simulates environmental situations to determine effects on evolution over periods of time. This lab experiments with the evolution of finches on two different islands over 100, 200, and 300 years. By manipulating parameters that influence natural selection, the effects that natural selection have on the evolution process can be studied.

The Avis Papyrus, more commonly known as the Carmel Origami Bird, native to the sparsely spaced Cool Creek Islands, was subject to a study of its evolutionary success. These birds must travel long distances to get between the islands they inhabit in order to survive long enough to produce offspring; meaning that being able to fly long distances aids in their fitness. The development of these beneficial characteristics are possible because of something called natural selection. Natural selection is the gradual process over the course of generations where a species gradually develops and excludes traits and characteristics (Fukuyama, 2004). This is to help increase reproductive success of an organism and increase the animals fitness. The experiment looked at how natural selection led to their evolution and it’s raw data shows evidence that the Origami Birds have met evolutionary success due to natural selection.

The Galapagos Penguin (scientifically known as Spheniscus Mendiculus), is one of the smallest types of penguin on the planet and is the easiest to distinguish as it lives the furthest north than any other penguin species. It has distinctive white marks on its face, beak and chest as well as a “C” shaped line that stretches across its upper body. The Galapagos Penguins are native to the Galapagos islands, they live in colonies and are sedentary meaning that they only venture as far as 3 miles away. Sadly, they are currently listed as endangered by many sources such as WWF (Worldwide Fund) with numbers fewer than 2000.

The Galapagos Islands consists of thirteen major islands and over a hundred smaller islands located along the Ecuadorian coast. The islands are home to a variety of unique species such as sea lions, sharks, rays, and 26 different species of native birds. Thirteen of these birds are Darwin’s finches. These finches are known to be the “world’s fastest-evolving vertebrates” due to their bodies quickly adapting to the rapidly changing environment (Robertson, N.D. , para.1). Their DNA chemical makeup causes these adaptations to occur. The finch’s most noticeable feature is their evolutionary adaptations, due to the briskly changing environments.

Emperor penguins are majestic creatures; their life cycle portrayed in the film "March of the Penguins" shows a lifecycle fraught with dangers, including exposure to extreme environmental conditions and aggressive predators. Despite the challenges, the breed has survived. It may be argued that survival is the result of natural selection and the adaptations which have developed, but it is also argued luck plays a role.

Emperor penguins (Aptenodytes forsteri) in the Antarctic are fascinating flightless birds that are able to withstand incredibly harsh environments, where wind chills can reach to -76°F. Even though these penguins are able to survive the freezing temperatures, their breeding success and mortality rates are based primarily on the sea ice concentration (SIC) and sea ice extent (SIE) throughout the seasons. Sea ice concentration is a variable for climate scientists and nautical navigators to find the area of sea ice compared to the total at a given point in the ocean, whereas sea ice extent refers to a region as “ice-covered” or “not ice-covered.” During the late 1970s, there was an elongated atypical warm period with reduced

More than 20 football fields of trees are removed each minute. Logging can affect plants and animals by losing their homes. Predator - prey relationships will alter which can then cause a trophic cascade by overpopulation from the prey or extinction of predators. Also keystone species could be removed by these factors. So these living and nonliving factors could affect an ecosystem in many ways. Changes affect the ecosystem strongly in ways which population could boost in biodiversity or severely diminish the population of both plants and animals.

The king penguins favorite food is fish and some squid. In colonies in the open they have territories but no nest. The male penguins size is 16.0 kg ,and a female size is 14.3 kg. The scientific name is the aptenodytes patagonicus. No other penguins have a longer breeding cycle then the King penguins.

Emperor Penguins are my favorite animals to this day. This is because in 2nd grade my teacher made us write essays on animals from Antarctica such as Polar Bears and Sea Lions. When my teacher assigned me the Emperor Penguin I didn’t think much of it at the time, but when I began my research about the animal, it slowly caught my interest.

To swim past looming icebergs, avoid the predatory sea lions, and travel in sync with a colony of penguins proves how

Another is the mom penguins go through a lot for 2 months and sacrificing their lives from getting getting eaten by predators or masking sure there little ones are also safe. Also the parents have to be responsible to bring enough food back and to bring it back on time for the little ones.
