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 and the lecture are both about the bees existence on Earth as early as 200million years ago on the basis of very old fossil structure that resemble bee nest. whereas the reading states that the structure is doubtful to assure the presence of the bee at that time, the lecturer suggests the possibilty of the presence of the bee in the mean time. The lecturer puts forward several compelling reasons which cast doubt in the points made in the passage.

First of all, according to the reading, the unavialability of concrete bee fossil before 200 years ago by the people proving the bee's existence in question before that time. However, the lecturer refutes the argument. he says that the fossil may have not been found today due to an absence of the tree, which produce resins to preserve fossil of bee, during the time. So, the presence of fossil of bee may not be found today, but it doesnot mean that they had not existed at that time.

Secondly, the reading claims that flowering and bees have mutually dependent relationship; while flower evolved about 150 millions year ago, the presence of bees before that is impossible. Nevertheless, the lecturer disputes this claim. he believes that the bees used to survive in the environment before flowering plant by feeding on non flowering plant like pine. In addition, he points out that after the development of flowering plant, they might establish this obligate relationship with the flowering plant that we see todays.

Lastly, the passage states that the fossils has lack of details to call this as bees fossil. On the other hand, the lecturer dismisses this point by saying that even the fossils have not specialized structre, caps, they were proved as the bee structure with an evident chemical structure. it has serve the evidence of water proofing stucture that modern bee have today.
