Evolution of penguins :: essays research papers

Evolution of penguinsFor this developing project, I choose to look into Penguins. The assortment for this animal is as follows K Neornithes, P Palaeognathae, C Neognathae, O Pelecaniformes, F Procellariformes, G Graviidae, S Spheniscidae. The send-off fossil penguin that was entrap, 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 contempt the fact that the species was located far past from Antarctica. Since that discovery many more fossils were found and were go out back to the Miocene sequence and three others from the Pliocene era. Several fossils were dated to the Late Pliocene era and others from the Recent era. The soonest avian fossil found in the southern hemisphere is verbalize to have existed in the Eocene cartridge clip about 38-54 one jillion million historic period ago. in that location is evidence that at least(prenominal) three of the modern penguins (Aptenodytes, Spheniscus and Pygoscelis) went dead within the last 4-5 million years. The re importantder 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 rear from an ascendant that flew rough 40 million years ago. The common ancestor is assumed to have been somewhat akin to a modern-day descend petrel or auk in appearance and behavior. The main evolutionary advantage of braggy up aerial flight is the better swimming ability in particular being able to swim quickly helps in contracting lean and being able to nosedive to great depths (studies show that some modern penguins can dive up to 300meters) which greatly increases the range of forage which is available to hunt. Another major specify in the evolution of penguins is probable to have been the availability of vas t amounts of nutrient in the ocean. The beak up of the Proto- genuine, Gondwanaland, was completed around 200,000,000 years ago and left the Antarctic continent completely surrounded by an ocean. The resulting ice-cold currents established in the southern ocean (once the polar ice strong-armer had formed) made them rich in nutrients and then led to the huge 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 classification for this animal is as follows K Neornithes, P Palaeognathae, C Neognathae, O Pelecaniformes, F Procellariformes, G Graviidae, S Spheniscidae. The first fossil penguin that was found, is today being held in the British Museum of Natural History.

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 a bility 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.
