Revise evolution for Edexcel with BBC Bitesize. Charles Darwin developed the theory of evolution by natural selection. All living species are classified using the system developed by Linnaeus.

Abstract. Penguins are a remarkable group of birds, with the 18 extant species living in diverse climatic zones from the tropics to Antarctica. The timing of the origin of these extant penguins remains controversial. Previous studies based on DNA sequences and fossil records have suggested widely differing times for the origin of the group.

The nervous system also can allow the penguin to gain extra heat from muscle movement e.g shivering. Keeping cool: During summer (December to February) Emperor Penguins are at risk of overheating. Penguins temperature may rise above 39 degrees Celsius. Penguins can lose heat through many means to help maintain thermoregulation and homeostasis.

Penguins Natural Selection, Survival Of The Fittest and Adaptation Survival of the Fittest Genes are passed down from generation to generation the one that fit most to their environment will survive and therefore evolution will occur due to these adaptations. In present day the.

Reading and writing about penguins is a great seasonal activity to do in January or December to kick off your informational writing unit.Here is how we studied penguins, extracted information from on-level text, constructed our introductory sentence, and wrote a paragraph about what we learned about penguins.

Now, evolution applies to many aspects of animal and human life from the speciation of finches to human health and disease. In this review, I have summarised origins and evolution of penguins. Due to the incomplete fossil records, the precise evolution of penguins is not yet understood.

Evolution: loss of aviation Penguins are birds which, during their evolution, have forgotten to fly. They're not the only birds, because emus, nandus, the well-known ostriches and coursers such as kiwis and wekas, and the flightless cormorants of the Galapagos too, aren't able to fly too.

This study provides additional support for a scenario of penguin evolution characterized by an origin of flightlessness near the K-T boundary, dispersal throughout the Southern Hemisphere during the early Paleogene, and a late Cenozoic origin for the crown clade Spheniscidae.

Slang and Contractions-you should not use slang or contractions in your essay either. Keep the paper in the formal style.

The difference (if any) in the rate of evolution between penguin and non-penguin outgroups might affect the age estimation. Therefore, we estimated the age of crown penguins after excluding all outgroup species and using only the penguin sequences and three internal fossil calibrations (nodes 6, 7 and 8).
