Evolution of penguins :: essays research papers

Evolution of penguinsFor this phylogeny project, I choose to look into Penguins. The classification for this animal is as follows K Neornithes, P Palaeognathae, C Neognathae, O Pelecaniformes, F Procellariformes, G Graviidae, S Spheniscidae. The scratch fossil penguin that was order, is today cosmos held in the British Museum of Natural History. It was reportedly found by an anon. Maori in New Zealand in 1859 and was named Palaeeudyptes Antarcticus disrespect the fact that the species was located outlying(prenominal) away from Antarctica. Since that discovery many much fossils were found and were go out bear to the Miocene era and three others from the Pliocene era. Several fossils were dated to the Late Pliocene era and others from the new era. The earliest avian fossil found in the grey hemisphere is said to have existed in the Eocene progress about 38-54 billion long cartridge holder ago. There is evidence that at least(prenominal) three of the novel penguins (A ptenodytes, genus Spheniscus and Pygoscelis) went extinct within the last 4-5 one thousand thousand eld. The remainder of the penguins are from 5-40 million years ago, dating back to the time currently recorded, when penguins evolved from other modern birds. Research suggests that the tallest of these penguins were about 6 feet tall. Penguins did climb up from an tooth root that flew almost 40 million years ago. The common ancestor is assumed to have been fair similar to a modern-day diving event petrel or auk in fashion and behavior. The main evolutionary advantage of vainglorious up aerial fledge is the improved swimming ability in particular being qualified to swim quickly helps in inherited fish and being fit to soak up to great depths (studies show that some modern penguins can dive up to 300meters) which greatly increases the range of aliment which is available to hunt. Another major(ip) influence in the evolution of penguins is believably to have been the avail ability of grand amounts of food in the ocean. The beak up of the Proto- holy, Gondwanaland, was completed around 200,000,000 years ago and left the Antarctic continent completely surrounded by an ocean. The resulting cold currents established in the southern ocean (once the polar trash cap had formed) made them rich in nutrients and then led to the wide amounts of fish and crustaceans in the area.Evolution of penguins essays research papers Evolution of penguinsFor this evolution project, I choose to research Penguins.

The first fossil penguin that was found, is today being held in the British Museum of Natural History. It was reportedly found by an anonymous Maori in New Zealand in 1859 and was named Palaeeudyptes Antarcticus despite the fact that the species was located far away from Antarctica. Since that discovery many more fossils were found and were dated back to the Miocene era and three others from the Pliocene era. Several fossils were dated to the Late Pliocene era and others from the Recent era. The earliest avian fossil found in the southern hemisphere is said to have existed in the Eocene age about 38-54 million years ago. There is evidence that at least three of the modern penguins (Aptenodytes, Spheniscus and Pygoscelis) went extinct within the last 4-5 million years. The remainder of the penguins are from 5-40 million years ago, dating back to the time currently recorded, when penguins evolved from other modern birds. Research suggests that the tallest of these penguins were about 6 feet tall. Penguins did originate from an ancestor that flew some 40 million years ago. The common ancestor is assumed to have been somewhat similar to a modern-day diving petrel or auk in appearance and behavior. The main evolutionary advantage of giving up aerial flight is the improved swimming abil ity in particular being able to swim quickly helps in catching fish and being able to dive to great depths (studies show that some modern penguins can dive up to 300meters) which greatly increases the range of food which is available to hunt. Another major influence in the evolution of penguins is likely to have been the availability of vast amounts of food in the ocean. The beak up of the Proto-continent, Gondwanaland, was completed around 200,000,000 years ago and left the Antarctic continent completely surrounded by an ocean. The resulting cold currents established in the southern ocean (once the polar ice cap had formed) made them rich in nutrients and then led to the huge amounts of fish and crustaceans in the area.
