Some fossil structures looking like bee nests have been found in Arizona, and now both the reading passage and the lecture discuss the possibility of bees existing 200 million years ago. Albeit the reading passage proposes three reasons to prove that these insects didn't exist at that time, the lecturer challenges all of them, and believes none of the skeptics are conceiving.
First of all, based on the reading passage, there is no fossil available from 200 million years ago, as the earliest fossil found dues to 100 million years before. However, the lecturer states that a sticky liquid produced by trees is needed to preserve bodies of bees which was rare about 200 million years ago, thus it's probable that bees just couldn't be preserved. Therefore, since trees didn't have the right substance to preserve bees, there's no foundation of fossils. And although it's true, it's not a plausible reason for refuting bees’ existence.
Moreover, in accordance with the author, bees and flowers have a close evolutionary history. Thus, due to the fact that flowers appeared 125 years ago, it's not possible that bees existed prior to flowers. The lecturer claims that bees are mutually dependent, and it's true, yet it's likely that bees used to feed on none flowering plants in evolutionary period, and then after flowers came to existence, bees adapted their feeding habits.
Finally, according to the reading passage, fossilized structures have some differences with the modern ones, and thus it's likely that the structure belongs to another insect, like wood-boring beetles. However, the lecturer states that even though the fossilized chambers lack caps, in chemical analysis scientists discovered that both the fossilized chambers and the modern ones are built from a water proof substance. In conclusion, the structures found in Arizona would be a good evidence of bees' existence 200 million years ago.
