Ancient Penguin Discoveries and Evolution

Discovery and evolution of ancient penguins In a recent BBC news article, Ivan Noble discussed the key to the mystery behind the era of complex molecular evolution of ancient penguins. Even though animals are unlikely to do research, prehistoric penguins are still the foundation for research, research, and discussion in the Antarctic modern scientific community. Cute and beautiful prehistoric relatives of contemporary birds have colonies of "high density and high mortality characteristics", so the mass sedimentation of the subfossil skeleton is continuously preserved in the cold Antarctic environment I have done it. "

For the question "How can a penguin not be able to fly?" The simplest answer is the word evolution. The modern penguins are the descendants of Weimanu Penguin, which existed about 62 million years ago. Wyman Penguin is already flying birds, and they are adapted to the ability to swim in the water. Wimanu Penguin's ancestor is unknown, and scientists are not sure at what point the penguins lost their ability to fly and got the ability to swim in the water. Why Penguin decided to abandon its ability to fly scientists who had been captured for a long time. The reason is that the emperor penguin needs a journey of up to 60 kilometers, if the penguin can fly, the same thing can be done in hours. In addition, although penguins are excellent swimmers, they are prey to other creatures and can swim underwater like seals. So then why do penguins lose their ability to fly? That's why

Penguins are aquatic birds that can not fly, mainly residents of the Southern Hemisphere. There are 17 kinds of penguins. Most penguin species can be found on Antarctica and its surrounding islands. Only the Galapagos Penguins live in the Galapagos Islands closest to the equator. Over time, the penguins experienced a cycle of evolution and lost their ability to fly. Penguin gave up the ankle feathers used to help the penguins swim. The evolution of penguins is a very hot topic for researchers. Many research papers and articles on the evolution of penguins have been published

A fossil of "gigantic ancient penguin" was discovered. They stood about 5 feet. (Think about the Crazy Mountains penguin: "A huge and unknown species is bigger than the biggest species of the known emperor penguin." The mountainous area is a mammal fossil PBS documentary ("Bone Digger") Recommended for discovery There is no mention of HPL (For books on Long see Criticaster 31 (2001).)
