Summarize the points made in the lecture, being sure to explain how they challenge specific points made in the reading passage.
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.
Points made in the lecture contends contrarily to the reading that bees might actually be existent 200 million years ago. The lecturer provided explanations to counter each of the three reasons why critics in the passage doubt the existence of bees at that time.
First, the lecturer suggested that no fossil of actual bees around 200 million years ago does not directly translate to the absence of bees during that period. During that time, she explained, the common means of bees fossilization, certain type of resin from trees, may not be present. Therefore, bees could have still existed 200 million years ago. There just happen to be no "container" to hold the bees for us to discover until much later.
After refuting the first point in the reading, the professor explained that bees survival might not depend solely on flowering plants. Before the advent of flowering plants, bees might have been feeding off other types to food sources, such as ferns and pines. This invalidates the claim in the passage that bees could not exist 200 million years ago because there were no flowering plants in the period.
Finally, a last piece of evidence supporting the existence of bees 200 million years ago was provided in the lecture. Chemical analysis of the fossilized structures found in Arizona indicated that these ancient structures contain waterproofing material analogous to those of their modern bee hive counterparts. This nullifies the doubt cast by the passage dictating that these structures did not belong to bees.
Points made in the passage explains that bees' existence 200 million years ago is plausible. The lecture explained how it was possible for bees to be present at that time without being fossilized and without food support from flowering plants. It also mentions how the fossilized structures found in Arizona may actually be made by bees according to the chemical formulation. These information put the conclusion drawn in the reading in doubt.
