Both reading and lecture discuss whether bees where exist 200 million years ago. While the passage casts doubt on their existence, the professor disagrees and states some points that show bees can be alive such long years ago.
First, the article claims that actually there is no fossil of bees to ensure this theory. The speaker point outs that although it is a true fact, but this is because there was not a substantial material required for fossilization in that era. The trees which produce these materials were pretty rare back then.

Second, based on the passage bees need flowers to feed on, but there were not any flowers 200 million years ago. Again, the professor supports that bees could feed on other nonflowering plants. these nonflowering plants could be the antecedent of the flowers which are known in the modern era.

Third, the reading mentions that the structure found lacks some details in which there is no caps in the nest. In contrast, the lecturer reveals that there is some chemical evident that shows some similarities between the old and the modern nest. Modern nests use some waterproof material to prevent damages may cause be rain. These chemical materials have also been found in the old structure as well.

In conclusion, we can see that although the reading mentions some points rejecting the theory, the professors states some reasons reinforcing the idea that bees existed 200 million years ago.
