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 lecture are both about the existence of bees on earth as early as 200 millions years ago. Whereas the reading passage states that bees cannot be present such long time ago and put forward three arguments to support, the lecturer believes that these arguments can be proved wrong. She believes bees do exist 200 years ago
Firstly, the author points out that there is no fossils of actual bees, thus cannot believe that bees exist that long years ago. This point is challenged by the lecturer. She says that it is because of the lack of trees producing certain sticky resins which is required for preserving fossil of bees o those early days. Furthermore, she argues these types of trees later came into existence which made it possible to keep fossils of bees later.
Secondly, the author contends that the absence of flowering plants where bees feed on normally can be another possible reason for rejecting this theory. The lecturer rebuts this argument. She suggests that earlier days bees might have fed on no flowering plants like pines and ferns.She elaborated on this by mentioning that bees later adapted to feed on flowering plants.
Thirdly, the author states that lack of some details on the structures found in Arizona can be another reason to refuse the bees existence 200 years ago. The article establishes that fossilized structures were made by other insects. The lecturer, on the other hand, posits that even though the fossilized chambers lack caps, which is used to close the bee nest, chemical evidence of the structures supports that it is made up of a water resistant material found on modern bee's nests.
