The material discusses the old fossil sturctures that have been discovered inside 200- million-years-old fossilized trees could resemble bee nests. While the reading claims that these structures were not created by bees becasue of several arguments. The listening disagrees and mentions that it is perfectly possible that these sturctures could be bee nests and adds that all the arguments that states by the reading are not convincing.
First, the author contends that there is no prevesred bees dated back 200 million years ago. On the other hand, the professor opposes this and posits that it is true that the earliest preserved body of a bee is 100 million years old. The lecturer adds that it does not mean that bees did not exist before that. The listening explains that the reason is bees are capable to be preserved in fossilized tree resin. The speaker mentions that these trees were very rare 200 million years ago and may be they became common latter. Furthermore, the lecturer states that bees might exist but there were no trees that could produce that right type of resin to preserve them.
Second, the writer points out that 200 million years ago flowering plants did exist. On the contrary, the lecturer refutes this and mention that bees might exixt and feed on other non-flowering plants, such as furn or pine trees. In addition to that, the professor states that bees could adapt to feed on flowering plants latter.
Third, the reading mentions that the fossilized structures lake spiral caps. Nervetheless, the listening contradicts this and posits that there is a chemical evidence ensure that it is bee nests. The professor explains that modern bees produce specific waterproof material that has certain chemicals. The lecturer adds that by examining fossilized structures found that they have the same chemical material that used by the modern bees.
