TPO 40
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 states that it is unlikely that bees lived on the earth 200 million years ago because of three main reasons. The speaker, however, finds the idea dubouse and casts doubt on those reasons.
First of all, the reading claims that since no fossils of real bees have not been found from 200 million years ago, there were not existed then. Conversely, the lecturer brings up the idea that for fossilizing the body of bees, the liquid is necessary which is produced by a kind of tree. there is the possibility that those tree were rare in that period of time, therefore, maybe bees existed that time but could not been fossilized.
Another issue that the reading maintains is that due to the fact that bees feed on flowering plants, and no flowering plants have been found from that time, bees have not existed before 125 million years ago. On the contrary, the speaker underlines the fact that bees could use non-flowering plants as food source then, and after the flowering plants were evolved enough, bees adapted to consuming them. Moreover, this relationship between bees and flowering plants were stabled.
Finally, the writer if the passage argues that although fossilized structures found in arizona are similar to modern bees' nests, there are some details that do not match. In contrast, the lecturer mentions that a chemical evidence have been found in the modern nest material which is waterproof. Additionally, the same chemical exists in the fossilized structurs of arizona nests. As a result, because both nests contain same content, we could say that bees have lived on the earth 200 million years ago.
