Did bees (a type of insect) exist on Earth as early as 200 million years ago? Such a theory is supported by the discovery of very old fossil structures that resemble bee nests. The structures have been found inside 200- million-year-old fossilized trees in the state of Arizona in the southwestern United States. However, many skeptics doubt that the structures were created by bees. The skeptics support their view with several arguments.
No Fossils of Actual Bees
First, no fossil remains of actual bees have ever been found that date to 200 million years ago. The earliest preserved body of a bee is 100 million years old—only half as old as the fossilized structures discovered in Arizona.
Absence of Flowering Plants.
A second reason to doubt that bees existed 200 million years ago is the absence of flowering plants in that period. Today's bees feed almost exclusively on the flowers of flowering plants; in fact, bees and flowering plants have evolved a close, mutually dependent biological relationship. Flowering plants, however, first appeared on Earth 125 million years ago. Given the bees’ close association with flowering plants, it is unlikely bees could have existed before that time.
Structures Lack Some Details
Third, while the fossilized structures found in Arizona are somewhat similar to nest chambers made by modern bees, they lack some of the finer details of bees’ nests. For example, chambers of modern bee nests are closed by caps that have a spiral pattern, but the fossilized chambers lack such caps. That suggests the fossilized structures were made by other insects, such as wood-boring beetles
The reading passage and lecture have conflicting opinions about whether or not bees would have existed before 200 million years. The article strongly postulates that there are remains of bees nest found inside tree fossils. although the skeptics cast doubt about the origin of the nest structure. On the other hand, the listening adamantly delinates that there is possibility that the structure found inside the fossilized trees would have made by bees owing to the fact that none of the three arguments are convincing.
First and foremost, according to the author of the excerpt, the first fossil belongs for a body of the bee is 100 million years old. Therefore, there are no remains of bees would have preserved before that. Nonetheless, the lecture offsets these points by declaring that the kind of trees that would have preserved the body of bee didn't exist at that time. Furthermore, this kind of trees that produce a special resin to preserve the bee was very scarce at that time. which means the bees might have existed 200 million years ago.
On top of this, the speaker in lecture further points out that it's really possible that could have fed on nonflowering plants, for instance, urine and pine trees. Moreover, the bees may have adapted to feed on flowering plants when they existed. These claims refute the writer implications of how bees wouldn't have existed without flowering plants 200 million years ago.
The article lastly asserts that the nest structure that has been found in Arizona looks like the nest structure of bees in present days. However, fossilized nest lacks comprehensive details, such as caps that have a spiral shape. The speaker in lecture counters these points by insisting that there is a clue that has been found in structure fossils, which is the nest have a chemical substance that would make it waterproof. Plus, modern bees nests have the same kind of waterproof.
