These fossils are said to be related to the carnivorous theropods, such as tyrannosaurs and velociraptors. Theropods have been related with birds and this new fossil’s feet as well as teeth relate it to the extinct carnivores. Also, due to the size and shape of the foot and leg bones, the animal is said to be a running dinosaur about six to eight feet tall. Thousands of miles away from this excavation sight and during the same week, William Hammer and his research team were in the mountains of Antarctica, about thirteen thousand feet, specifically near the Beardmore Glacier. The pelvis to a plant-eating dinosaur was found buried in solid rock.
There was a time when man existed, during the era of the Wooly Mammoths, now the African Elephant and the Wooly Mammoth both have highly similar bone structures which means they could have evolved from one another but the Elephant that is indicated with the similar bone structure is the African Elephant the Wooly Mammoths survived in the ice age. In Conclusion, as of today evolution is still a theory and will continue in that state until society builds advanced machines that are proven to be accurate which can either correct or incorrect theories. But the question is if evolution is ever proven false how did life form on planet earth in the beginning.
The woolly Mammoth was an herbivorous mammal that lived in the cool and dry open steppe-tundra of the Northern Hemisphere from late Middle Pleistocene or earlier. The woolly mammoth is said to have been about the same height and weight as the Indian elephants, but its overall shape was clearly different. The hind legs were much shorter than the forelegs, which resulted in a distinct slope to the back. The skull was narrower from front to back than those of modern elephants and there was a large dome on the top. As specified by its name, the woolly mammoth had a dense coat of hair and its outer layer consisted of long, coarse guard hairs, while a dense layer of fine wool lay underneath.
Recently, scientists studied Jurassic Park to calculate the actual speed (using the length of the dinosaur's strides) of T. Rex in the movie. They found that it was actually moving at a walking speed of about 12-mph (the jeep in the movie was supposed to be moving at about 40mph)! Many scientists familiar with the principles of biomechanics (physics applied to living organisms) think that tyrannosaurs could move fairly fast, maybe 10-20 mph, but not as fast as the smaller theropod dinosaurs. Smaller tyrannosaurs like Albertosaurus may have moved faster than the bigger ones like T. Rex. Some think that this was probably true for young tyrannosaurs, too.
The Warm and Cold Blooded Nature of Dinosaurs The debate of whether dinosaurs were cold blooded or warm blooded has been ongoing since the beginning of the century. At the turn of the century scientists believed that dinosaurs had long limbs and were fairly slim, supporting the idea of a cold blooded reptile. Recently, however, the bone structure, number or predators to prey, and limb position have suggested a warm blooded species. In addition, the recent discovery of a fossilized dinosaur heart has supported the idea that dinosaurs were a warm blooded species. In this essay, I am going to give supporting evidence of dinosaurs being both warm and cold blooded.
The evolution of the elephant specie initiates the modification in the genetic traits of an elephant through sequential generations; hence the independent species divided into separate divisions. The subspecies therefore evolved and developed independently, and ultimately expanded and branched out to form advanced species, resulting in the formation and evolution of the modern elephant specie. The current elephant is a large herbivorous mammal, native in Southern Asia and Africa. The elephant species is the largest existing land animal, belonging to the family Elephantidae, and the order of Probiscidea. The elephant is characterised by the possession of a versatile trunk, capable of grasping objects and ivory tusks.
This order includes the placental mammals; most of which are land animals. Carnivora first appeared about 55 million years ago in the late Paleocene. The Order is split up traditionally into to suborders, the Pinnipedia and the Fissipedia. Although Fissipedia includes all land animals it is paraphyletic and therefor is not considered a valid taxon. Pinnipedia is interesting in the fact that it seems they have evolved from a bear-like land-living ancestor.
In fact, a nature preserve covering a sixty-square-mile area has already been established in Siberia in the hopes that it will one day soon be inhabited by mammoths . While society may not currently be ready for the revival of creatures that went extinct thousands of years ago, technology certainly has that goal in its sights. Since cloning and genome sequencing techniques are still in need of refinement, it will give naysayers time to come to terms with researchers aspirations. After all, it seems that sooner or later, mammoths will walk the Earth again.
Along with other colleges, Bernard successfully excavated a frozen, fully in tact, woolly mammoth that is said to be over 20,000 years old. (Head scientist: Bernard Buigues) What is a woolly mammoth? A woolly mammoth is a similar ancestor of the African and Asian elephants of today. It belongs to the same mammal classification known as proboscidenas, or mammals with long trunk like noses. Both of these breeds come from the same family tree but are distinct cousins.
Were Neanderthals the same as modern humans, or were they an entirely different species? This is a major topic of debate among Anthropologists, and many people strongly argue each view, backing their opinion with evidence from physical remains and inferred ideas about behavior. The proponents of the separate species hypothesis believe that they had a common ancestor, but Neanderthals and modern humans were separate species. They argue that the Neanderthal line was a dead end, and that for some reason Homo sapiens thrived while they went extinct. Most of their evidence comes from the fossilized bones of Neanderthals and Cro- Magnons, or modern man’s ancestors (Shreeve, 150).
