TPO 45 Integrated Writing TaskDid 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 ye

Both the passage and the lecture discuss fossils that have been found 200 million years ago and their resemblance to bee nests. The author presents some problems with those fossils and states that they did not belong to bees. On the other hand, the professor argues that those problems are unconvincing, and those fossils were related to bees 200 million years ago.
First, the passage states that no bee fossils have been found from 200 million years ago. Nevertheless, the lecturer rejects the author's view and illustrates that there is no bee fossil date back then because the fossils have not been preserved. She states that bee fossils preserve in tree resins, and in that time, those kinds of trees were rare and became common millions of years later.
Second, the reading claims that bees feed on flowers of flowering plants, and in that time, the flowering plants did not exist. Nonetheless, the professor opposes this view and states that then, bees fed on non-flowering plants, such as ferns and pine trees. She mentions that after the flowering plants evolved, bees adapted to them and have been dependent on them since then.
Finally, the author argues that those fossils lack some specific details about bee nests, and therefore, they are not bee nests. However, the speaker refutes this idea, saying that there is chemical evidence that supports the idea that bees made those nests. She says that modern bees use some particular chemicals to waterproof their nests. The evidence shows that those fossils have the same kind of chemicals.
