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.
The lecture and the reading are about the existence of bees 200 million years ago. the reading states that, bees were not available during that time and provides three main reasons ti support this theory. The lecturer casts doubt on what is presented in the text and refutes every of the reasons given on the text . She does not feel that bees were not present 200 million years ago.
First of all, the lecturer argues the first reason that fossil remains of actual bees are not present because bees could not be preserved at that time. A sticky liquid is secreted by trees to preserve the bees, but such trees were not originated earlier, instead they become common much later. It might happened that the bees had exhausted in the absence of these sticky liquids.
Secondly, with regard to the second reason, absence of flowering plants, the lecturer explains that when flowering plants were not present, bees might be feeding on non flowering plants such as ferns and pine trees. They might have adapted feeding on flowering plants later. Therefore the lecture argues the claim that bees could not exist in absence on flowering plants.
Finally, the lecturer objects the third reason - structures lack some details, She points out that chemical evidences support that these structures are made by earlier bees. Earlier bees had special water proofing substance to preserve the nest, so they might not require structures like to preserve their nests. This is in direct contradiction with the claim in the reading passage that the fossilized nests are made by another kind of insects.
