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 reading passage states three theories about the fossilized bee neet that paleaontologists found in the State of Arizona in the United States which they cast doubts about its relation to modern day bee nests. Whereas, the lecturer points out that these hypopheses are not convincing, and it is pretty possible that the nest have been made by bees back then.
Firstly, the author insists that scientists did not find any bee fossils dated to 200 million years ago. The professor, however, argues that this is because the ancient bees were not be able to be preserved. She says that a especial secreat of tree called Reson is responsible for bees preservation, and trees with that feature were pretty rare at that time, but now there are lots of trees with Reson. As a result, we can not deny the presence of bees because of that, maybe there were bees but because of the lack of Reson they did not became fossil.
Secondly, the article says that bee's food which were flowering plants appeared on earth 125 million years ago. In contrast, the speaker reckons that eventhogh there is a close mutual relationship between bees and flowering plants, but flowers are not their only source of food. She mentiones that bees feed on none flowering plants such as fern and pine trees, and through time they adopted themselves to flowering plants.
Lastly, the writer deems that the lack of some fine details in that fossil reject it's belongness to bees nest. On the contrary, the lecturer refutes it by saying that bees back then used special material to water proof their nest and they did not need that spiral shape to be pr
