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 passage discusses that researchers discovered a very old fossil structures that resembled bee nests. However, the passage states that there are many doubt the structure were created by bees and provides three reasons to support this. In contrast, the professor in the talk explains what said in the reading is incinvincing and rejects all these three reasons
Firs,t the text claims there are no remains of actuall bees that dated to 200 million years ago. While the professor exoplains that may be it is because 200 million years ago there were not trees with especial resin that it was necessary for fosilizing. So, because of the lacking of the resin the condition for fosilizing was not available. As a result, it is not a good reason to reject that these fosils are not related to actual bees.
Second, the reasing asserts that there is no sign of flowering plants 200 million years ago. Furthermore, the text explains that the mainly food for bees are available along side with flowering plants. However, the teacher rebuts this idea by describing that there is a chance that ancient bees used unflowering plantts to feed but after a lot of years by flourishing flower plants they have adapted to use flowering plants. So, the reason that mentioned in the text is impractical.
Third, the passaged believes while the fossilized structure that found in Arizona is similar to bee's nest, but also there are differences between them. The professor in the lecture rejects this by illustrating that researcher after many analysis detected a chemical ingridient that there are in fossils and also in modern bees. So, this similarity proves that these fossils are really related to ancient bees.
