Over the past few years, fragmentary remains of an extinct member of the bear family called the giant short-faced bear have been discovered at sites across North America. Because the remains of this creature are incomplete, there has been extensive argument over the nature of this bear's lifestyle, and particularly over its diet. While some researchers have suggested that the short-faced bear was an omnivore, like modern black and brown bears, there is substantial evidence that the giant short-faced bear was probably a carnivore that almost exclusively ate meat.
First, it is the animal's bones that give us the clearest proof of the short-faced bear's carnivorous nature. The most recent bone remains have been dated to 13,000 years ago, and testing of those bones has shown that they contain a very high ratio of nitrogen-15 to nitrogen-14. This ratio of isotopes is a chemical signature which indicates that the animal those bones belonged to was a carnivore.
Second, the sheer size of the bear is a clue to its diet. The short-faced bear would have stood over eleven feet tall on its hind legs and was one of the largest bear species of all time. The largest bear species today is the polar bear, a species which is almost exclusively carnivorous. Given that today's largest bear is a carnivore, it is likely that the largest bear of the recent ice age shared similar dietary preferences.
Third, the legs of the short-faced bear were ideally suited to running down fleeing prey animals. The short-faced bear had the longest legs of any bear species and claws that aligned forward, rather than in the spread out formation we see on bears today. The structure of its bones and claws would have enabled it to maintain a carnivorous diet by allowing it to run down and catch a wide variety of fast-moving ice-age prey species including elk, caribou, and horses.
Both the reading passage and the lecture discusss about the nature of diet regarding giant short-faced bear. While the reading passage suggests that the bears are carnivore, the lecture contradicts this, the lecture explains that the bears are omnivore.
First of all, the reading states that giant short-faced bears bone indicate that they are carnivore, because of the nitrogen-15 which the scientists found in their bones. On the other hands, the lecture mentions that the notrogen-15 is not a hundred percent conclusive test, It does not exclude the presence of other diet. Not only this but, other omnivores contain nitrogen in their bone too.
Secondly, the reading passage states that the huge size of short-face bears is a clear indicator of their diet. and the closest bears to their size are polars bear, which are also a carnivore creatures. This contradicts directly with the lectures. The professors points out that evey bears have different enviroment. For the polar bear they secure their food from the ocean therefore, meat is the only option they have. While the short-faced bears eat plants to supplement their diet.
Finally, the reading passage mentions that giant short-faced bears compraed to any other bears type have the longest legs and claws that aligend in specific way to to help them to run and hunt preys. Again this contradicts with the lecures. The speaker states that it is true that they have long bones, but they are thin, and this would be dangerous for them attack other large preys. That will aquire them high effeorts to run in these legs. At the end he mentions that the short-faced bears run over large area to provides variety of food not only animals.
