Recommended: Ancient penguin evolution
A flightless bird that has flippers that are used to help the bird swim and can be found in regions that have extremely cold climate. These are characteristics that describe a penguin. For millions of years, penguins have been known as one of the many flightless birds on Earth. However, scientist believe that penguins were once birds that flew high in the sky. It is known that about 55 million years ago, penguins were already completely adapted to the life in water, in a warmer environment than today. The penguin's ancestors have undergone many physical changes throughout the years, for the penguin to arrive at its current state. The benefits that penguins once had from flying was that penguins were easily able to escape from predators. As
The four-pointed forkbird has the best suited evolutionary fitness. By the end of the activity, there were only two two-pointed forkbirds, one one-pointed forkbirds, and seventeen four-pointed forkbirds. This shows that four-pointed forkbirds have a better chance of surviving and passing on their traits.
After watching March of the Penguins I was browsing the internet while I was trying to figure out which direction to take the essay in, because there were too many possibilities for the topic. Soon I found myself watching Monty Python, when the perfect sketch to start this paper on comes on. A newspaper reporter comes on saying "Penguins, yes penguins what relevance do penguins have with the furtherance of medical science? Well strangely enough quite a lot" He moves into a joke about research not being accidental. Then he picks up of the penguins "Nevertheless scientists believe that these penguins, these comic flightless web-footed little b@$#ards are un-wittingly helping man to fathom the uncharted depths of the human mind." The news cast flips to the scientist who introduces himself then states "...having been working on the theory postulated by the late Dr. Kramer that the penguin in intrinsically more intelligent than the human being." From there a multitude of science spoofs lead to the confirmation of this theory of penguins being smarter, even though it is clearly pointed out that the penguin's brain is smaller than of a human being. This causes the penguins to rise up and take over the roles of humans. After careful consideration I decided to discuss this clip as there really is no better way to introduce how animals are used in film as entertainment. Whether it is a crazy Monty Python sketch or the heartwarming love story that is March of the Penguins both were created for many reasons, but the most influential was the desire to earn money. For now just keep Monty Python on the back burner it will have significance later, lets shift to dealing with the questions being posed about March of the Penguins. How did March o...
The population of the whooping cranes most definitely gets affected from precipitation, because the population gets affected negatively with high precipitation levels present, while positively with low precipitation levels. The population of the whooping cranes gets affected this way because if there were high precipitation levels for a year, the hatching success rate drastically decreases from the precipitation, who damages the eggs laid by the cranes. By either breaking the eggs, making the cranes not be present to incubate their eggs, or actually destroying the birds’ nests. Also, the high precipitation levels may even cause a few fatalities, which is a very serious problem involving this particular endangered species. While with low precipitation

If puffins are disturbed by humans they will leave their nests and will not come back. This has led to the extinction of puffin colonies in parts of the European coastline.
Like I said moments ago, the penguin is known to be witty, meticulous, inscrutable and they of course live on ice! First of all, I can be witty if I want to, and I spend half of my time on the ice. By that, I mean at the arena playing or practicing ringette. Ringette is a part of me and it always will be. I love the sound of my skate edge cutting into the ice. In addition to that, I love the way snow sprays off my skate when I make a quick stop as well. These are just some of the way that I can relate to a penguin. In conclusion to this paragraph, I am most like a penguin because I often enjoy the cold
These penguins lived after the Castastrophic event “Cretaceuous” that demolished the dinosaurs and many other species. Based on the DNA analyses and avaiable evidence of modern birds, we think the modern bird- lineages, including penguins, some how managed to survive through the Cretaceuous. Also it’s not shocking these fossils were found in New Zeland. The South Pacific and Southern oceans were free of predatory mammals, had abundant food, and had space for Penguins to breed. But the Southern Pacific is not the only area where Penguins inhabit. Many of modern penguins “Aptrenodytes” are located in the Antarctic. Recenelty it was discovered that there was a over looked feature on the surface of the fossil penguins flipper bone. These grooves were easily missed because the look was similar to tendons and muscles in the same area. It was discovered that these grooves were blood vessels that make up a counter current heat exchanger called “humeral arterial plexus” which allows penguins to limit the heat loss through the flippers. Also it helped Penguins maintain their core body temperature in cold water allowing them to survive long journeys in the cold waters. Although Penguins have luckily been able develop these traits to survive the dramatic shifts in climate, the world population can not mistake their success as resilience towards global warming.

The endangerment of penguins is being perpetuated by human actions and these actions must cease for penguins to stay alive. Simply saying penguins are endangered is not suffice. There are many kinds of penguins, each having its own status of vulnerability and danger. Just like all other living things, penguins have a Scientific Classification. Theirs is as follows.

The penguins’ habitat is ocean and rocky beaches. They live near the Cromwell Current to obtain food, because many fish swim on that current. They utilize the beaches, especially when they are nesting, and lay their eggs in holes or caves on the islands. Their diet consists of eating small fish that are found less than 30 meters deep in the water, because they don’t like to swim farther down than that (Animal Diversity Web).
Throughout the various phyla discussed evolutionary advancements are relevant. Starting from the basic, simplistic life forms of a sponge, up to the intelligence of an octopus and advance organ systems of Annelida the changes have only improved. Some species changed and evolved because as populations grow, they spread out farther and different conditions begin to affect their life. Why some species haven’t changed is because their body plan and system works for the environment they inhabit. Evolution has helped animals spread out all over the world and adapt to various conditions, seen in the habitats Aschelminthes can prosper in.
Penguins are one of my favorite species of birds. They look like a bunch of men in tuxedos at the beach. Although they are considered birds, none of them are capable of flying. They live in climates and locations that range from the warm Equator to the freezing Antarctic. Penguins are so cool that they have become the stars of many television commercials. Of the seventeen species, it is the Emperor penguin that is the most interesting penguin. After all, how many fathers can go without food for two months, so that they can protect their off-spring twenty four hours a day?
