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.
In the reading passage, the author discusses three kinds of the reasons to illustrate that existing bees 200 million years ago is impossible, while the lecturer claims that what the reading passage states is not convincing and disputes those reasons presented in the reading passage by several proofs.
First, the reading passage states that there is no bee fossil remains dated to 200 million years ago and the oldest one was dated to the 100 million ago. Therefore, it is impossible bees exist before the 100 million years ago. By contrast, the lecturer opposes this view point by saying that bees fossils observed in the resin of the some trees besides this like of trees exhibit 115 million years age, so it is possible bees live before that.
Second, the writer makes point that todays bees need flower and flowering plants and the first flower in the world appears 125 year age. However, the speaker demonstrate a different idea that early bees was used some trees and after the first flower appears they adapting to feed flowers.
Third, the belief in the reading passage is that the fossilized structures found is lack of some of the finer details of the bees' nest, while the speaker views to this issue from an opposite angle. According to the speaker, chemical analysis shows the same water and chemical evidence. Consequently, this structure can be attributed to the bees.
