TPO 45 Task 1
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 passage states that a fossil found in nectar of an ancient tree which is very similar too Did bees. The fossil history has been estimated to 200 million years ago. Researchers are skeptical that the structure has been created by bees and they provide three reasons of support. On the other hand, the professor has an opposite notion and claims and refutes each the reasons.
First, the passage explains that the founded fossil is very old in comparison to the previous bees’ fossil which had been found. it is two times older. The professor challenges this reason by saying that the fossil has remained in a especial resin of an ancient tree which had been very rare 200 million years ago. Maybe this fossil of bees has remained by chance.
Second, the article states that no blossoming plants lived on earth 200 million years ago and the bees and flowering plant has a mutual relationship. The lecturer does not adopt this explanation and says that it is likely that earlier bees fed on the other plants such as firns or pine trees and after advent of flowers, an adaptation has occurred.
Third, the passage avers that the structure of the chambers has some deficiencies such as spiral caps so this structure is not similar to bees’ pattern. The professor refutes this reason as well. She said that bees protect their nest by an especial water proof substance which consists of a distinctive chemical component and this component is existed in the ancient fossil.
